PV-based Water Pumping Equipments

Working principle and precautions for use of photovoltaic water pumpsWorking principleThis photovoltaic water pump system uses energy storage batteries as an energy buffer and regulator. When the light is sufficient, the photovoltaic panel converts solar energy into electricity. Part of the electricity is directly supplied to the water pump, and the excess electricity is stored in the energy storage battery. When the light is weakened and the photovoltaic panel power generation is insufficient to meet the needs of the water pump, the energy storage battery automatically discharges and replenishes electricity to ensure that the water pump continues to work stably. Its specific working process is: the photovoltaic panel generates direct current, which first passes through the charging controller. The charging controller controls the electricity to charge the battery or directly supply the water pump according to the battery power and the output of the photovoltaic panel. The water pump a…
