·The system mainly consists of PV array, inverter, controller, submersible pump and water tank.Cables are used for both solar panels and submersible pump to realize the wiring of thesystem.The water pipe applicable to the submersible pump is adopted.

·This system does not have storage batteries, completely powered by solar energy, thus realizing a cost-effective purpose. The customer can prepare an appropriate water tank to store water for later use. High-efficient AC submersible pump is adopted for the system, satisfying different requirements (lift and flow). makes the AC pump outstanding, compared with the DC pump.

·The system is characterized by Maximum Power Point Tracker technology, regulating the working of the pump automatically to realize the maximum generated energy for the system. Meanwhile, the stands for the PV array also has the tracking function (by manual regulating the stands), thus significantly increasing the working time of the system to pump more water.

·Automatic control is adopted for the system such as: automatic start-up and shut-off respectively in the morning and evening, automatic shut-off for full tank and water shortage in the well. Therefore, manual control is not a must. Meanwhile, protection measures are taken for the rotation jam of the pump, 3 phase equilibrium etc. thus prolonging the service lifetime of both the pump and inverter/controller.
