Solar water pumping system consists of four parts: solar panels, solar pumping inverter, three-phase ac pump, and water storage. The solar pumping inverter converts DC power produced by the solar panels to ac power which drives AC pump to pump water from the borehole, river or lake to the storage.
The inverter applies high efficiency MPPT algorithm to maximize the
utilization of the power harvested from the solar panels. It will make the
system to maximize efficiency; highest output of water. The solar pumping
system fulfills concept of low carbon emission, energy conservation,
environmental protection aiming at improving the supply of water in areas of
low insufficient supply.
Accessories will be added in solar pump system to realize more functions. AC input function, high voltage solar charger to charge battery and to save power, ac filter to protect the pump.
Solar pumping systems can be applied in areas with high solar irradiation and that have no electricity or the electricity supply is insufficient; such as:
PV combiner box shall be used for solar pumping system from 2.2kW to 132 kW, in order to reduce connecting cables for easy maintenance and low cost to keep safety and reliability.
The combiner box has the current counter-attack, over current, over voltage function, and lighting protection as well. Customized design possible.
Mechanically activated device for dry run protection in applications
with solar pump systems.
The switch can be used to detect the water level within a well. When water level in the well dropped below the level of the well probe, the solar pump inverter will stop the pump to protect. It is also used for
overflow protection, once the water in the tank reaches the highest level
which water level sensor set, the solar pump inverter will stop to save
energy and water.
The outlet filter connected between solar pump inverter and pump. It is used once the cable between the inverter and pump is too long
