Enhance the solar generator capacity of photovoltaic power plants, I have a coup

Renewable energy is an important energy resource in meeting energy needs, change the energy structure, reduce environmental pollution and promote economic development plays an important role.

As one of the main representatives of renewable energy, solar generator photovoltaic power is by far the most ideal human new energy, renewable resources is the best, clean, low-carbon, environmental protection, no noise pollution and light pollution are characterized by other solar energy storage sources can’t match is an important part of the restructuring of the energy, the fight against global warming and haze powerful "weapon". PV policy from the "Golden Sun" to the distributed along the way, power stations of solar backup power has been a key measure of the value of energy saving, and investment income is directly linked to the value. How to get the best effect power generation has become the focus of everyone's attention.

PV solar generator operation and maintenance (O & M for short) is to ensure that the most direct and effective way of generating capacity, thereby shortening back this time and improve revenue generation. And many users never clean los solar panel comprehensive also not aware of its importance. Therefore, the surface area of the solar panels thick dust hinder part of the sunlight into the cells, reducing the generating capacity.

And hire some professional solar storage energy operation and maintenance service personnel about a week to complete the cleaning work 6400 assembly. After cleaning the glow component life, bright as new, with blue sky and reflect the same color. All panels after thorough cleansing, photovoltaic solar power backup generator  plant is expected to increase by about 10%, bringing environmental and economic benefits can’t be ignored!

Finally, it summarizes the considerations for solar backup generator panels cleaning of photovoltaic power plants:

1.    Must be cleaned to work under irradiation intensity is weak, it is recommended before and after sunrise or sunset period;

2.    Cleaning personnel should wear personal protective equipment, such as rubber gloves, to prevent accidents;

3.    You must use a neutral cleaning solution, do not use aggressive solvents or wipe the battery with a hard object;

4.    It’s strictly prohibited in high winds, heavy rain washing.

Advantages and disadvantages of solar generator

7. The photoelectric conversion by means of the solar energy storage directly into electricity.

The disadvantage of solar generator

1. Although solar generator is huge, but it was too decentralized, open to large-scale use of solar energy storage must be set large pet collection and energy conversion equipment, the cost of solar off grid system is still too high, affecting the promotion.

2. Due to the Earth's rotation and climate, season and other reasons, a large solar power kit off grid change, instability, cause difficulties to the normal continuous use.

3. The current solar generator conversion efficiency is not high, need further material Hard high conversion rates.

Solar generator electricity is green low-carbon energy

Photovoltaic solar backup generator has significant energy, environmental and economic benefits, is one of the best green energy, has become a common concern of all countries of the world focus on the development of technology and industry. Solar energy storage resources is extremely rich, widely distributed, and convenient. Develop photovoltaic power generation, including renewable energy strategic emerging industries, accelerate the adjustment of energy structure, the establishment of "independent, self-reliance, clean and sustainable" energy system, is our response to the dual problem of fossil energy shortage and air pollution fundamental way.

Solar generator electricity is green low-carbon energy

US National Renewable Energy Laboratory NREL, based on 13 different types of polycrystalline silicon photovoltaic system - Emissions (Europe 2005 2006 manufacturing level) of the full life cycle carbon dioxide, in the amount of solar solar backup power radiation per year to 1700 kwh/square meter, the system life 30 years, module efficiency of 13.2% -14.0%, the system power generation efficiency of 75% -80%, the average value obtained for each kilowatt generated within the polycrystalline silicon photovoltaic system life cycle carbon dioxide was 45g, the average value per kilowatt generated in thermal coal as a raw material for the whole life cycle of 1000 grams of carbon dioxide.

According to the World Wildlife Fund (WWF) statistics, in China's average sunshine condition, install one kilowatt photovoltaic system, can be made 1200 a year of electricity, can reduce coal (coal) uses about 400 kilograms, reducing carbon dioxide emissions about one ton, figuratively speaking, to install the equivalent of one square meter of solar photovoltaic modules of about 100 square meters of afforestation.

Photovoltaic solar electric generator generation system is running without fuel and water

As long as the place to get the light, you can use solar photovoltaic systems, unchecked altitude, geographical and other factors, the wide range of applications.

Simple photovoltaic system construction, operation and maintenance operations

Simple solar cell module structure, small size and light weight, easy to transport; easy installation of the construction, demolition migration; capacity according to different systems, modular installation, and easy to expand generation capacity at any time, greatly shorten the construction period. PV systems no mechanical moving parts, no noise, and more importantly, easy operation and maintenance, system reliability is improved operational stability. With the development of automatic control technology, the photovoltaic grid solar system can run unattended, operation and maintenance costs are significantly reduced.

PV system performance, stability, reliability, long life

The world generally believe that the life of crystalline silicon photovoltaic modules is 25-30 years. Here, the 25-year life of the component, refers to the power module warranty period, namely 25 years after the power components not less than 80% of the initial power, but does not mean completely without power components with little or electricity. Indeed PV module efficiency decay is a slow process, so more time can PV modules provide clean electricity within 30 years, even as humans continue.

Photovoltaic solar generator is to improve the climate bring positive energy bureau

PV systems in the power generation process itself, not only will not adversely impact on the surrounding environment, it can also play a game to the micro-climate improvement. Cover PV modules, PV power plant makes the venue shallow soil temperature remains stable, and the soil temperature is lower than the power off, so that reduce soil moisture evaporation, soil moisture has improved, near-surface air temperature difference between day and night narrow, these air, soil temperature and humidity conditions combined, help conserve soil moisture and nourish the microbes and vegetation, to improve the local ecological environment of photovoltaic power plants play a positive role.

How the new lithium solar energy storage technology to enhance the efficiency of the PV system

University of Southampton and REA Psystems collaborative research discovered a new type of lithium battery as the solar energy storage device PV systems, solar energy storage efficiency can be increased to 95%, can greatly reduce the cost of solar power.

Most current PV system also uses lead-acid batteries as the solar backup generator device, there is far, lithium iron phosphate battery replacement can give full play to its advantages, including improved storage efficiency, long life, low unit cost, and so on. The type lithium is used as an solar energy storage device, the energy efficiency can be increased to 95%, far more than 80% of the traditional lead-acid batteries, and has 1,600 charge-discharge life.

Lead-acid battery of solar generator energy storage device is used in most traditional photovoltaic systems. However, as the energy storage device, lithium batteries, especially the LiFePO4 batteries we use, have more favorable characteristics.

Collect these data, it is necessary to connect the lithium iron phosphate battery and off grid Solar System，PV systems installed in the building at the University of use provided by the REA Psystems specially designed battery management system. someone added, "Research shows that 95% of the lithium battery energy efficiency, and the most commonly used lead-acid batteries, only about 80 percent, while the lithium battery lighter and has a longer use than lead-acid batteries life. charge and discharge times can reach 1600 cycles, which means they do not need regular replacement.” 

Although before commercial photovoltaic systems, batteries need further testing. But studies have shown that, LiFePO4 battery is expected to improve the efficiency of solar power kit off grid generation system, and helps reduce installation and maintenance costs.

For a variety of energy sources (renewable or non-renewable), solar energy storage devices, such as batteries, plays an important role in terms of energy solar backup generator use, with the traditional lead compared acid batteries, LiFePO4 battery has a higher efficiency, longer life, lighter weight, cost less. we expect to be able to see such batteries are widely used in photovoltaic systems and other renewable energy off grid solar systems.

Solar energy storage green investments between those crisis years

Although the world has not yet come out from the bottom of the financial crisis, liquidity dried up, the recession, but for energy saving, environmental protection, investment and construction technology, venture capital enthusiastic, government gearing up. Crisis is to promote economic restructuring and industrial upgrading, the best time, but the direction is the transformation of solar energy storage system technology, which is the consensus of all investors. They may be from the IT, Internet transition from the field, "I hope the bottom up, the popular spirit of the Internet and methods have been introduced in the field of energy and environmental protection by the government and big business monopolies, release large amounts of innovation and wealth-creating opportunities. Financial Crisis Europe can make the financial system on the verge of collapse, but also a serious blow to the venture.

According to the survey, the global investment in technology of solar energy storage system in 2009 with a total investment of about $ 1 billion in funds under the crisis the solar solar backup power system technology has not dried up, government investment body. Solar energy storage system into the world $ 436 billion. United States, Britain, Germany, France and other countries will invest a lot of money to invest in solar energy storage field, focusing on energy-efficient buildings, low-carbon car and public transport and renewable energy. Local governments are also planning to use legislation to further increase the green industry policy tilt and encouragement. Especially notable is the US President Barack Obama vigorously promote "green New Deal" to revive the economy to find a new growth point. He proposed an ambitious investment plans revival, the core is to improve energy efficiency and accelerate the development of renewable energy, renewable energy total to double by 2025, renewable backup power generator accounted for 25% of the total generating capacity.

Another referred to the United States to the 2050 greenhouse gas emissions in 2005 based on 83% of the market space and opportunities detonated make global venture capital and PE flocking to invest too much energy to the solar generator storage system technologies. 2008 total investment of $ 1.3 billion. New energy industry into a hot spot for investment, there are 28 Chinese companies listed at home and abroad. The world of mature technology into China, with China's manufacturing cost advantage, materials and processing innovation and speed to combine cost-effectiveness can play in the huge Chinese and overseas markets.

The key solar energy storage technology can reduce costs, how much cost reduction decided whether the market much. In China, generally reduced by 30 to 50% of the cost. When the financial crisis came, it will be further highlighted in green industry looming formation of the "Sino-US co-governed" Pattern: China's manufacturing cost advantage and combine the advantages of American technology, delivered to the two sides a huge market and globally. Benefit wealth suddenly detonated China PV industry hot green investment. We start from the environmental protection, including water, air and waste. Go slowly energy market, further to renewable energy. Renewable solar off grid system energy is developed simultaneously. First, solar and small hydropower mature applications, and wind energy. Then new materials and ecological agriculture. Finally, sustainable transportation, including battery, electric cars and public transport systems this. From the traditional concept of environmental protection, sustainable development, circular economy and fame and then the turning point that solar energy storage, but a lot of people to solar energy storage as "energy of luxury." Polysilicon material costs rise, the economic crisis overseas to reduce government subsidies, coupled with vicious market competition, resulting in short-term 34 100 solar business failures.

Higher technology, higher conversion rates, lower cost, field of electric vehicles, fuel cells and biodegradable material. China's PV industry into a mature manufacturing industry in a few years. US solar storage technology and market leader in the world, Prudent Energy a US technology company founded in 2006 specializing in the development of high-power, long-life green solar energy storage system: vanadium battery. Solar electric generator, wind power is not stable, and will bring pressure on the transmission network; while the traditional electricity grid to cope with peak demand expansion valley often by construction. With this large-scale solar energy storage systems can store electricity, perform clipping Pinggu power side management, reduce electricity costs and improve quality. Those islands dispersed off grid solar power kits vanadium TV can also be used to store electricity, find and enlarge the resource integration mode: the cost advantage of Chinese manufacturing, innovation and speed application development and foreign high-tech combine to produce the most cost-effective products to the global market. Further research and development of large-capacity capacitor, more focus on mining storage, nuclear power, energy-saving materials, and the effective use of recycled energy.

The difference between grid and off grid solar generator system

The difference of Grid solar system and off grid solar power kits are different only the english word initially , now meant in the context of photovoltaics is an existing electricity grid. The two grid and off grid are essential for the photovoltaic.

A.      Grid solar System in photovoltaics

In a grid solar system is a photovoltaic system that produces electricity, this solar energy storage is then fed into an existing to public network. The solar backup power generator is NEBEM (the interconnected modules) an inverter necessary because in public power grids alternating current flows. In the grid solar systems, a distinction is in photovoltaics between different concepts:

1.       Grid Solar systems in which the photovoltaic system is used to supply a load parallel to the public grid. The decentralized solar energy storage is produced close to the consumer, so large transport losses can be excluded.

2.       Grid solar systems in which the photovoltaic system supplies the consumer an alternative to the public network. Here, the consumer is indeed also connected to the public network, the solar power backup generator is decentralized, so the draw-off produced. But instead feed surpluses into the public grid, these are primarily stored in the energy storage. This Grid Solar System provides mainly for a higher security of supply and is often used in weaker supply networks, as so-called backup system.

3.       Grid Solar systems supply consumers in parallel with the public network,the known grid solar  systems, such as are used in Germany and other industrialized countries. Grid systems that exert a so-called backup function are rather used in emerging markets or developing countries.

B.      Off Grid solar System in photovoltaics

In an off grid solar system is a stand-alone system. Such a photovoltaic system is therefore not connected to a public electricity grid and only works with energy storage. Such off grid solar systems or stand-alone systems have greater market share in the early days of Phovoltaik. Today they are primarily in cottages used, which are not connected to a public network because of the distance. Off grid solar power kits photovoltaic systems are also used in boats or caravans. Another application for Off Grid solar system photovoltaic is for example in the operation of desalination plants or water pumps. the market share is growing, especially in developing countries. 

Recommendations on family purchased and installed solar energy storage

Government subsidies to various countries and regions to inspire more people to become electricity producers. With its own solar power system to earn some income. Solar storage entirely suitable for these motives. I'll show you a few simple suggestions on how to experience the solar energy products.

After the installation of solar energy storage products can be added to store solar power can be for new users, the combination of photovoltaic power generation systems and storage systems is wise. In both cases, the experts see as the current use of personal behavior, personal files and creates a set of conditions to the house. "There is due to its compact design, there is no problem of space. Under normal circumstances, the energy stored in the cellar or utility operation.

Home use solar generator energy storage using two batteries (lead acid, lead - gel) or lithium-ion. "Choose what type of storage battery, and ultimately become a problem, depending on your needs and realities on the ground, the main difference lies in memory, energy density, life expectancy and prices in the installation planning to ensure that all components are matched to each other PV systems to power plants, inverters, storage, and charging electronics and a very high rate of self-consumption to achieve.

You can benefit from state subsidies 

Each national bank may provide low-interest financing for storing up to 30% of the cost, as long as the solar electric generator suppliers to meet the qualification criteria. If in doubt, have to learn more about the services and preferential bank loans for funding of your offer. In addition, each country and region has to purchase additional electricity policy. 
Install solar energy storage

Need to correctly choose a professional sales and installation of solar power backup generator provider. If the memory settings, the system is fully automatic. Like all electrical devices should also be checked regularly memory errors, in terms of security, the need to safeguard consumer rights and proper installation procedures. 

Who collects solar power and time offset of use, consumption of solar energy itself and less excess power supply to a large part of the public grid. Peak production and electricity purchases. This saves the new power line, reducing the cost of energy conversion of the general public. The operator must not forget to register at the local network operator of solar power storage. Network operators can assess the demand on the power grid is normal. The operator of photovoltaic power solar generator systems and storage Contact your local distribution network operator federated system.

Composition structure portable solar generator power supply system

The main components of portable solar generator power supply system are: solar charge controller, batteries, inverter, cabinet and structural parts.

1. Solar cell components: the solar cell module is a solar-powered system in the central part of the solar power system, the highest part of the value. Its role is to the sun's radiant energy is converted to electrical energy stored in batteries or sent to, or promote the work load. Quality and cost of the solar cell module will directly determine the quality and cost of the entire system.

2. Solar generator controller: Solar controller's role is to control the working status of the entire system, and played a battery charge protection, over-discharge. In the large temperature difference, the controller should have qualified temperature compensation function. Other additional features such as light control switch, when the switch should be the controller options.

3. Battery: lead-acid batteries, small micro-system, also used nickel metal hydride batteries, nickel cadmium batteries or lithium batteries. Its role is when there is light in the solar cell module confessed energy stored up, and then released when needed.

4. Inverter: current generated by the solar cell to DC, charging into the battery storage. The inverter will be 220V direct current into alternating current, for a variety of load. Of special note is, under normal circumstances the inverter must be connected to the battery and use, if the direct connection of the solar energy storage cell, sunlight will be due to the instability in the environment does not work properly.

5. Housing and other structural parts of off-grid solar system: the main place to place over the device, according to different products, different box sizes. Meanwhile, according to differences in product functionality, there may be a DC output, power strip, such as different porous structures.

How to use off grid solar system products and get return on investment

Now by the financial market downturn, the stock market is always ups and downs, the real chance to earn from small, most investors only cast money into and be rewarded. If there is a product off grid solar system not only meet our daily needs and can easily earn high fees, over three to five years to be profitable during this period can’t be charged extra electricity costs.

Now all over the world to respond to the needs of environmental protection, encourage the use of solar generator energy storage products, which introduced a series of measures of financial subsidies generally high capacity PV off grid solar system energy storage power station not only for their own use can also be the transmission to the public grid. The each country can subsidize these additional power.

The following I will be in Germany, for example, a table clearly shows that ROI so that we can according to the size of their own area to install solar panels to convert solar compute power, the wider region to install more solar panels, and produce conversion of more power. that we can choose the higher capacity of photovoltaic solar energy storage products. the faster the greater the capacity of our returns generated.

Compared to the uncertainty of the stock, it is not that PV portable solar generator production capacity product is a good choice? Either support our cause, to meet our demand for electricity, and can be recovered in a short time we invested in solar energy storage products before buying costs. why not? As long as we together reduce the demand for traditional non-renewable energy, environmental protection of our road will go farther and farther, farther good. can according to the size of their own area to install solar panels to convert solar compute power, the wider region to install more solar panels, and produce conversion of more power. that we can choose the higher capacity of photovoltaic solar energy storage products. the faster the greater the capacity of our returns generated.

The attention of safety knowledge for installation of photovoltaic solar generator

"Safety " is the basic principle firstly. In order to successfully complete the photovoltaic solar generator installation tasks, you must something as the following.

1. Equipment manufacturers comply with the provisions of installation specifications and the necessary application codes and standards.

2. Prepared completamente

Full preparatory work for construction in remote areas is particularly important, we must ensure that all the materials needed to build power plants, equipment, tools, installation drawings and information brought to the scene. Site for a variety of emergency situations that may arise must have the appropriate preparations. Site construction leaders and key personnel should be familiar with the venue, transportation, topography, climate, and human environment, should know how to injured people evacuated as soon as possible. Be sure to prepare a communication tool with the outside world. Bring enough clothes, food and temporary accommodation appliance, which in the wild is very necessary temporary overnight.

3. Reasonable arrangements and strengthen coordination

The installation site of solar generator must be given ample time to work aside to ask, which is particularly important in inaccessible remote areas. Only in this way can calmly work site staff, to avoid in order to finish the work, the phenomenon appears hectic at work and accidents.

Construction project can not be completed on time may cause a lot of problems, such as increased costs. Inconvenience to local users, but also to the installers trouble. To install work smoothly requires a reasonable time, at the same time pay attention to the coordination of the progress of work solar backup generator . Whenever the next step before installation, all the necessary preparatory work must be done according to the requirements.

4. Prepare construction drawings and technical documents

Site preparation and placement of equipment must be accountable to all construction workers clear the site of all buildings, foundations, cable trenches, pipes, cable laying paths and walls and so must be accurately marked on construction plans and technical detailed log file.

5. Enhanced environmental awareness, the use of new materials and new technology

Stand-alone PV power plant built in remote areas generally untapped, near agricultural areas or water. Unreasonable installation may result in water pollution and damage to crops, livestock and even affect wildlife survival. The installer of off grid solar system should have the basic knowledge and understanding of environmental protection of certain hazardous substances. Note the use of new materials and new technology emerging as an alternative to harmful traditional materials and old craft.

All the people must remember that, in the power engineering construction, there is always the potential danger and insecurity, time can’t be taken lightly. Throughout the installation of photovoltaic solar energy storage and the installation is completed to ask the inspection process, we must carefully check each part of the system to ensure the safe operation of power plants and the safety of nearby residents or pedestrians construction workers.

Stand-alone photovoltaic systems are often located in remote areas, so the design and installation work will encounter difficulties such as transport, installation materials and other aspects. When designers or installers in planning the installation of photovoltaic systems in remote, should be planned and ready to install the tools and materials needed. It may not have specialized electrical shop near the remote installation site, so well-planned pre-construction is necessary. Due to the specific circumstances of each construction site is different, the installer should first examine the site before construction, detailed study should be required to list the tools and materials of off grid solar system.

Notice of the using solar generator energy

Solar generator photovoltaic cell matrix of light surface should be kept clean, such as lighting the surface of dust or other dirt falling objects, should be washed with water, and then clean gauze to gently wipe away traces of water, do not wipe with a hard object or rinse with corrosive solvents.

Mounted frame, junction box and the cleaning process

After module lamination is completed, loaded into the frame, junction box and module loading washing step. Install border, is to give a good assembly is mounted on a laminated aluminum frame, increase the mechanical strength of the components, further sealing photovoltaic modules de solar generator energy, extended battery life, and the battery pack leads to positive and negative busbars lead solder and junction box the corresponding terminal pin or plug welding, assembly and then cleaned.

The module junction box of solar backup generator should be checked regularly to prevent weathering. Package should be inspected once every quarter and wiring connectors each of the solar cell module, if there is a plastic package water, battery discoloration and loose fitting, off-line, corrosion, etc., should be cleared up.

corrosive solvents.

1.Consider installing an array of solar panels required azimuth, tilt angle.

2.Between the panels need to avoid blocking. It includes surrounding buildings (poles, house eaves, etc.)

3.Stent placement stability and robustness (considering the local meteorological data, such as hours of sunshine, severe weather, storm, etc.)

4.Trace distance and combiner box location. Try to walk the line and the average distance is short

5.Related accessories to meet the system requirements (such as terminals, with wire diameter, etc.)

6.Terminals should be strong, to prevent false or disconnection

7.Battery terminals should firmly (do not be short-circuited) Note polarity installation, to avoid explosions and fires    

These are the issues when installing solar energy storage must be noted that in order to achieve security and long life.

The applicability of new energy product portable solar generator

The technology of solar energy storage systems as the key to new energy development and the new energy era, it will change the energy landscape of the whole world. As long as solar energy storage system technology is more economical, it will open a gateway to a new era of global energy. Effective integration of electric vehicles, energy storage technologies and wind power, solar energy, can form an effective substitute for petroleum, energy security, and therefore the development of solar energy storage technology is more and more important and urgent, so its importance is self-evident.

With the continuous development of portable solar generator energy storage system technology, diversification and cost reduction, in line with the more different needs of families so as to be accepted by all, such off grid solar system is completely independent of the public grid system, Any place is very suitable for non-grid areas or travel, light and easy to carry portable solar power system. the networking system can be connected to the public grid system in order to achieve complementarity electricity, and even delivered to the grid system. system capacity to be based on each family or individual's own electricity consumption demand, personalized design.

Portable solar generator storage systems or solar off grid  kit system installation is very easy, you only need to connect solar panels can charge while and net system by simply connecting the public grid for charging. Convenient and flexible, simple to apply in line with the requirements of each consumer.

How to choose a solar generator kit for home accurately

When customers choosing a solar generator system, first of all according to their own needs that for pure lighting or household electric appliances, in addition installed off-grid or grid. If you are living without electricity shortage areas, you can only choose off-grid power systems and 1000 watts of small portable solar generator; en the area with electricity easily grid system and optional 2000W or more, so as to achieve the purpose of saving electricity costs.

1.The use of pure lighting or using appliances

Solar generator system is divided into two types according to their functions, family of DC lighting system one simple lighting; the second is that is can lighting and can be used for household appliances have 220V / 110V AC output power generation system. Lighting system features a simple and cost-effective, but not for household electric appliances.

2. Which is better the portable solar generator or modular

The portable machine is a portable and free installation features, ideal for outdoor camping, but due to the limited volume, storage capacity is too small, the high cost. Need a simple modular installation, large capacity storage, both practical and affordable more suitable for home users and home use outdoors.

3.Off grid solar system or grid

Current types of solar power generation systems have off-grid and grid, grid energy storage and two types of non-storage devices. Each of the components has the difference and suitable for use not the same place. Cost varies widely, higher cost of off-grid systems and network systems, energy storage devices and network storage devices and those without network system. Off-grid solar power system is suitable for use anywhere, but is only suitable for the grid can be incorporated into the public grid places.

4.About the size of system capacity

System capacity is the size of the solar power system size or the number of solar panels installed, and whether it is in the net or off grid solar power kits power systems for power generation systems from net buyers need to pay attention to distinguish the size of the panel or inverter the size of the output, the inverter output capacity is not associated with the system.

Solar power system is not a standardized product and suitable for all users, to be based on the user's situation to design and configuration, in different places, using the type will be different. To have the intention to install solar power systems in order after the customer must understand clearly the right choice for solar power systems.

Portable Solar generator photovoltaic energy storage system introduced

Portable solar generator photovoltaic energy storage system introduced

In addition to the space station, all other PV systems are subject to sunshine during the day and did not affect the evening sunshine. And we want to use electrical appliances, day or night, we must choose to solve this problem portable solar energy storage battery through the inverter function convert.

Storage and management of electrical energy in photovoltaic system plays a crucial role in the photovoltaic power generation system has been mindful of the solar energy storage device is commonly used lead-acid batteries, but its short life cycle, low power density, volume and other maintenance disadvantages and costs are high, due to the unstable energy, space and other characteristics of large battery can cause premature failure or loss of capacity, and further increase the cost of solar backup generator.

Lead-acid battery charging There are many ways, including the constant current charging, constant voltage charging, constant current limiting charging, charging two stage, three-stage charging, fast charging, intelligent charging, equalizing charging methods. PV systems taking into account the energy, limited investment costs and charging power of special features, and therefore in charge control PV systems has its particularity.

1. The constant current charging is performed with a constant current charging, during charging as the battery voltage changes the current to be adjusted so as to be constant. This method is particularly suitable for the battery of solar generator has a plurality of batteries in series for charging, the battery capacity to make backward easy to be restored, the best time for small current charging mode.

2.The constant voltage charging means at a constant voltage to charge the battery. Therefore, in the initial charge due to low battery voltage, charge current is large, but gradually increased as the battery voltage, current decreases. In the late charge only a small current through the charging process so that it does not have to adjust the current. Constant current charging relatively speaking, this method of charging current is automatically reduced, so little analysis of gas charging process, the charging time is short, low energy consumption and charging efficiency up to 80%, as the charging voltage selector appropriate, within 8 hours charging is completed. Backup power generator capacity to make backward easy to be restored, the best time for small current charging mode.

3.The three-stage charging:

A) constant current charging phase, the charger current is kept constant, a rapid increase in filling power, the battery voltage rises

B) constant voltage charging phase, the charger voltage is kept constant, charge into the electricity continues to increase, the battery voltage to rise slowly, the charge current drops

C) the battery is full, the charge current drops below the float conversion current, the charger voltage is reduced to the float voltage

Charge controller for photovoltaic array output power is controlled based on the actual state of the system, in a certain way back level power supply, including MPPT mode, current limiting mode and constant voltage mode. System configuration certain capacity supercapacitor, except as an energy reserve means, but also on the output of photovoltaic energy for filtering, optimized battery working environment (including the charge and discharge currents). Battery directly connected load, the main energy reserves as a grid solar system device. Parallel controller is super capacitor energy transfer to the battery control link, control its purpose is to make the battery work in an ideal state and the charge-discharge cycles at least.
