The three phase solar water pump inverter directly obtains DC power from the solar panel and converts it into AC power to supply the water pump. The maximum power point tracking (MPPT) and the maximum use of solar energy can be obtained by adjusting the real-time output frequency according to the intensity of sunlight. Solar photovoltaic water pump system consists of 3 parts: 1. Solar panels, 2. Solar water pump inverter, 3. Water pump.
1.The system automatically starts in the morning and stops in the evening. It can run perfectly whenever there is sunshine, with no need of back-up battery.
2.Applicable to and suits all applications require water pumps.
3.Compatible with all types of solar panels and Ac pumps.
4.Remote monitoring for real time operation status and switching on/off by GPRS.
5.Good performance even in cloudy weather.
6.In the long run, the return on investment is much higher than diesel generators.
7.Equipment with perfect protection, requires no man to be on duty, runs fully automatically.

The three phase solar water pump inverter system uses the durable energy from the sun, works at sunrise, and rests in the sun, without personnel care, without fossil energy, without comprehensive power grid, independent operation, safe and reliable. It can be used with drip irrigation, sprinkler irrigation, seepage irrigation and other irrigation facilities to effectively solve the problem of cultivated land irrigation, improve production, water saving and energy saving, and greatly reduce the input cost of traditional energy and electricity. Therefore, it has become the most effective way to use clean energy to replace fossil energy, and has become a new energy and new technology application product of the global "food problem" and "energy problem" comprehensive solution.
