The photovoltaic array composed of the system mainly converts the sun's light energy into electrical energy to provide working power for the load water pump motor. The photovoltaic water pumping inverter or controller controls and regulates the operation of the solar water pump, uses the electric energy emitted by the solar array to drive the water pump, and adjusts the output frequency in real time according to changes in sunlight intensity, so that the output power is close to the maximum power of the solar cell array.
