PRODUCT Work Principle
Off-grid PV systems are widely used in remote mountainous areas without electricity, islands, communication base stations and street lamps and other application areas. PV array in the case under solar light into electricity through solar charge controller to power the load, while giving the battery pack; in the absence of light, through the solar charge controller powered by a battery pack to the DC load, while also directly to the independent battery power inverters, inverter through independent reverse into AC power to the AC load.
PV off-grid PV systems are generally composed of solar modules square, solar charge controller, battery pack, off-grid inverter, DC load and AC load and the like.
( 1 ) a solar cell module
Solar modules solar power system is a major part , but also the value of the highest solar power system components , its role is to convert the sun's radiant energy to DC power ;
( 2 ) Solar Charge Controller
Solar Charge Controller , also known as "PV Controller" , whose role is issued by the solar cell module to adjust and control power , maximize battery charge , and played a battery charge protection , over- discharge protection effect. Place in a large temperature difference, solar controller should have temperature compensation function.
( 3 ) battery pack
Its main task is battery energy storage in order to ensure that the load -day electricity at night or rainy.
( 4 ) off-grid inverters
Off-grid inverter is the core component of off -grid power system, is responsible for converting direct current to alternating current for AC load use . In order to improve the overall performance of photovoltaic power generation system to ensure long-term stable operation of the power station, the inverter performance is very important.

FAQ
[ Q ] when the network from the solar photovoltaic system installation needs attention ?
[ A ] system works when the specific installation , you should consider the following factors:
1 , consider installing an array of solar panels azimuth , tilt angle .
2 , between the panels need to avoid blocking . Including the surrounding buildings ( poles, house eaves , etc. ) .
3 , stent placement stability and solidity ( considering the local meteorological data , such as hours of sunshine , severe weather , storm , etc. ) .
4 , the alignment distance and combiner box location. Try to walk a short distance and the average line .
5 , related accessories to meet the system requirements ( such as terminals , with wire diameter , etc. ) .
6 , terminals to securely prevent virtual connection or disconnection .
7 , the battery terminal firmly ( do not be short-circuited ) Note polarity when installing to avoid explosion and fire.
8 , the controller general has a corresponding distribution protection measures . But the wiring process should also be taken to prevent reverse polarity, short circuit and so on. Avoid unnecessary trouble. Note placement angle, to avoid the rain immersion (except waterproof controller or enclosure).
9, the system with inverter, the inverter is connected to the battery to be connected to the positive and negative. Not connected to the controller output. General Off-grid controller output is the default DC output, which also comes with protection against DC load. Since the inverter with AC load will be unstable, it is proposed to connect to the battery, in addition to the need to load the necessary distribution protection to safeguard the security of the system.
10 , the construction of the system location must be open during the installation of the solar cell matrix may not have tall buildings or other things block the sun ;
11 , the controller needs to select low loss, good stability , long life controller. Figure out the controller is part of the positive and negative design or the design of the installation, so that the entire system is connected, installation help.
12 , the installation process , pay attention to the protection of electrical switches , to prevent live action , to cause unnecessary losses and troubles.
13 , the controller debugging needs attention to detail, so as not to affect the entire system engineering cycle.
During the installation process, you may also encounter some other temporary situation. As long as the attention to detail, seriously, usually very smooth.
