This article explores in depth the types of solar inverters suitable for small-power water pumps, aiming to provide accurate inverter selection references for agricultural irrigation, small-scale industrial water supply, and home courtyards, and help achieve efficient energy utilization and water pump drive with low-cost investment.
[pdf] DC pump dedicated inverter (also known as DC-DC controller) is directly connected to the solar panel, without the need for batteries or AC conversion, and optimizes the output of the photovoltaic array through the MPPT (maximum power point tracking) algorithm to match the voltage and current requirements of the DC water pump (such as permanent magnet brush less DC motor).
[pdf] The solar pumping inverter converts DC power produced by solar panels to AC power which drives AC pump to pump water from borehole, river, lake etc. to the storage device. The inverter applies high efficiency MPPT algorithm to maximize power harvested from solar panels.
