KEWO Solar Pump Inverter with MPPT Functions
Solar Pumping system becomes more and more popular, it can be applied to daily ( underground water), agriculture irrigation, forestry irrigation, desert control, pasture animal husbandry, water supply for islands, wastewater treatment engineering , and so on.
In recent years, with the promotion of the utilization of new energy resources, solar pumping systems are more and more used in municipal engineering, city center squares, parks, tourist sites, resorts and hotels, the landscapes and fountain systems in the residential areas. This system is composed of a solar array, a pump and solar pumping inverter, or GPRS remote control model.
Based on the design philosophy that it is better to store water than electricity, there is no energy storing device such as store battery in the system.
