Information

The photovoltaic controller is an automatic control device used in the photovoltaic power generation system to control the multi-channel solar cell array to charge the battery and the battery to supply power to the solar inverter load. It regulates and controls the charging and discharging conditions of the battery, and controls the power output of the solar cell components and the battery to the load according to the power requirements of the load. It is the core control component of the overall photovoltaic power supply system.

The function of photovoltaic controller:

Output power adjustment function. Communication function: identification function and protocol communication function, such as RS485 Ethernet, wireless network and other types of background management functions. Protection functions: electrical protection, reverse polarity protection, short circuit protection, overcharge protection, overdischarge protection, etc.

Photovoltaic controllers Currently the mainstream photovoltaic controllers on the market mainly include ordinary photovoltaic controllers, PWM photovoltaic controllers and MPPT photovoltaic controllers. The principle of the ordinary photovoltaic controller is to directly connect the output of the solar photovoltaic panel to the battery port, and cut off when the battery is full. Due to the internal resistance of the battery, it is difficult to fully charge the battery, and the solar photovoltaic panel is not fully used. The efficiency is only 70-76%.
