Dc Ac Hybrid Solar Water Pump Inverter Off-grid 220v 380v Mppt

Short Description:

Solar pump system, consisting of solar array, solar pump inverter, Ac water pump and tank, uses solar cell as power supply to directly take water from deep well, rivers, lakes and other water sources through the water pump.

The solar array absorbs solar radiation and converts it into electric energy to provide power supply for the whole system. The solar pump inverter converts the Dc output by the solar array into Ac and drives the water pump ; in addition, it adjusts the output voltage and frequency according to the sunshine intensity in real time to realize maximum power point tracking and to maximize the use of solar energy. When the sunshine intensity is low, the solar pump system can switch to grid power for complementary power supply.

Features

The hybrid 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.

Application

The hybrid 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.
