With the promotion of theutilization of renewable energy resources, solar pumping system are more and more used in municipal engineering, city center squares, parks,tourist sites, resorts and hotels, and fountain systems in residential ares.

The PV generator, an aggregation of PV modules connectedin series and in parallel, absorbs solar irradiation and converts it into electrical energy, providing power for the whole system. The pump drive controls and adjust the system operation and converts the DC produces by the PV module into AC to drive the pump, and adjust the output frequency in real-time according to the variation of sunlightintensity to realize the maximum power point tracking(MPPT). The pump driven by 1/3 phase AC motor, can draw water from deep wells, rivers and lakes and pour it into storage tanks or reservoirs, or be connected directly to the irrigation system, fountain system, etc.

According to the actual system demand and installation condition, different types of pump can be used, for example, centrifugal pump, axial flow pump, mixed flow pump and deep well pump.
