solar photovoltaic pumping system consists of three components: solar panels, PV pump inverters and three-phase AC pump. Solar arrays have several in-parallel solar cell components, absorbing solar energy and convert it into electricity for the entire system power. PV pump inverter can control and adjust for the system. It can convert DC produced by solar panels into AC to drive the water pump. According to changes in sunlight intensity to adjust the output frequency, the pump inverter can get the maximum power point tracking, and make the maximal use of solar energy
1.PV power system fully automatic operate, without on duty. Solar Water Pumping System is composed of solar cell arrays, pump inverter and water pump. Water storage replaces battery and directly drives pumping, with high reliability, at the same time, it can reduce system cost and maintenance costs.
2.According to the sunlight intensity to adjust pump speed, the output power close to the solar array maximum power; when the sunshine is sufficient, pump speed does not exceed the rated speed; when sunlight is insufficient, it will automatic stop working according to the minimum operating frequency.
3.Water pump is driven by three phase AC inverter. Pumping water from the deep well or rivers and lakes is poured into the water tank/pool, or directly connect irrigation system and fountain systems. To choose water pump depends on actual demands and installation conditions
