Ip65 High Protection Mppt Solar Hybrid Inverter Solar Pump Inverter For 1hp 2hp 3hp 4hp 5hp Water Pump

Short Description:

Solar water pump inverter known as solar variable frequency(VFD) is used to control the operation of solar water pump system. It allows you to adjust output frequency as per intensity of the sunlight to achieve the maximum power point tracking(mppt). It is an off-grid type inverter. The solar water pump inverter does not depend on the power grid. It works with a water level control system. Solar water pump inverter can help save ample energy, with improve control, and require less maintenance due to nearly no wear and tear, offering reliable protection to the motor, and reducing stress on valves, pipework and other related systems.

With the maximum power point tracking, you get the best output power possible from solar panel, which increases the performance of the pump while auto start/stop can save your investment.
