The solar water pump system comprises solar panels, solar water pump inverter, AC water pump, and water storage devices. The solar pump inverter converts the DC electricity generated by the solar panels into AC power to drive the water pump to operate. A built-in microprocessor continuously monitors the solar power output and adjusts the pump's operating frequency to optimize solar energy utilization. Additionally, input modules or AC power sources—such as the electrical grid or diesel generators—can be integrated as supplementary or backup power, enabling the system to operate continuously, 24 hours a day.
