25HP Borehole Solar Powered Water Pumping System consists of 4 parts: solar PV modules, PV pump inverter, Three phase AC pump and water storage device. The pump inverter converts DC power produced by PV module to AC power required by the pump. A microprocessor continuously monitors available energy levels and adjust pump speed, matching energy required to energy available. This enables the system to operate under varying solar insolation levels, and provide water throughout the day and through different seasons. The inverter untilize a high efficiency MPPT algorithm to maximize power harvested from PV module
System Working Principle: Compare to traditional AC Pumping System, solar pumping system shall work under variable frequency, as solar source power change over time. With the change of input solar energy, the rotate speed of pump motor is in change, and of course, the water output flow is also in change.
SYSTEM WORKING STATE: STANDBY- - -START- - -LIGHT LOAD- - -FULL LOAD- - -LIGHT LOAD- - -STOP- - -STANDBY- - - POWER OFF
WATER YIELD CONDTION: WATER OUTLET- - -SMALL WATER- - -RATED FLOW- - -SMALL WATER- - -NO FLOW
