Off – grid photovoltaic power is a solar application system which is independent from public electricity operation.
● It has no interaction with external grid system.
● It has battery storage which can provide electricity load independently.
 | Solar Panels Solar panel can transform solar energy into direct current electricity. |
 | Photovoltaic Control The photovoltaic controller is mainly used to regulate and control the DC power from the solar cell module, and to charge and discharge the battery intelligently. ● According to the grade of current voltage and the capacity of the solar cell module , u can configured appropriate photovoltaic controller. ● Common sizes: DC12V、24V、48V、110V、220V |
 | Battery Group Batteries is mainly use for electricity storage in order to store electricity load at night or rainy days. ● According to the requirements of DC voltage grade of the system, u can configured out of the number of batteries in series and parallel systerm. ● Try to configure1 or 2 sets of batteries , u can select the large capacity of batteries. The common size of batteries are 12V and 2V. ● The following principles shall be followed when the battery is connected in series and parallel: the same specification, manufacturer. It should install and use at the same time. |
 | Inverter Inverter is a transform machine which can transform DC electricity to AC electricity. ● The selection of inverter is based on the characteristics of load (such as resistance, inductive or capacitive) and the size of power. ● The inverter is classified according to the output waveform: sinusoidal wave and non sine wave (square wave, step wave) |
