Analysis of main parameters of photovoltaic controller The photovoltaic controller is the key equipment in the photovoltaic power generation system, which is mainly responsible for the management of the electric energy generated by the solar panels, ensuring the safe charging and discharging of the battery pack, and improving the overall efficiency of the system. When choosing a photovoltaic controller, it…

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…

Type of photovoltaic controller Parallel controller When the battery is full, the output of the photovoltaic array is shunt to the internal parallel resistor or power module using electronic components, and then consumed in the form of heat. Because this method consumes heat energy, it is generally used for small, low-power systems, such as voltage within 12V, 20A systems. This…

Photovoltaic controller functions high voltage (HVD) disconnect and recovery function The controller should have the function of input high voltage disconnect and recovery connection. undervoltage (LVG) alarm and recovery function When the battery voltage drops to the undervoltage alarm point, the controller should be able to automatically emit sound and light A warning signal. low voltage (LVD) disconnect and recovery…
