The working principle of photovoltaic controller
Collection and monitoring
The photovoltaic controller collects the output current and voltage in real time by connecting the positive and negative terminals of the photovoltaic cell pack. These data are an important basis for judging the charging and discharging state of the battery energy storage system.
Judge the status
Based on the collected current and voltage data, the photovoltaic controller can determine whether the battery needs to be charged or discharged. When the battery needs to be charged, the controller will open the output channel of the photovoltaic cell pack to convert the photovoltaic power into battery power; When the battery needs to discharge, the controller will close the output channel of the photovoltaic cell pack, and the electric energy stored in the battery is converted into AC power output through the DC-AC inverter.
Control output
In order to ensure the safety and stability of the battery energy storage system, the photovoltaic controller will adjust the output power of the photovoltaic cell pack according to the charging and discharging state of the battery, climate and other factors. In addition, the photovoltaic controller also provides a variety of protection functions, such as over-charge protection, over-discharge protection, over-temperature protection, short circuit protection, etc., to ensure that the system can operate safely under abnormal conditions.
