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)
