YCB2000PV High-performance vector lnverterSolar pumping system The YCB2000PV solar pumping system serves to provide water in remote applicarions where electrical grid power is either unreliable or unavailable. The system pumps water using a high-voltage DC power source such as aphotovoltaic array of solar panels. Since the sun is only available during certain hours of a day and only in good weather conditions, the water is generally pumped into a storage pool or tank for furher usage. And water sources are t...
