Alfa Power Solution manufacturers 3 Phase VFD Inverter’s for Solar Water Pumping Application that include the MPPT Charge Controller, the Inverter and all the circuit breakers and connection points to make installation fast and easy. These Pre-Wired Panel (PWP) systems are modular by design so they can be stacked up to provide power for 1 H.P. to 32 H.P. for a variety of pump sizes. The fact that one size can provide the wide spectrum of needs means that the local distributor need only stock and support a single product.
For high amounts of water, a large AC pump is usually required. These pumps require well regulated 3 phase AC voltage and current.
By using an AC variable speed controller called a Variable Frequency Drive (VFD), the pump motor will have the proper voltage and current. The trick is to supply DC from the PV array directly into the DC bus inside the VFD. The normal AC input is not used. As the sun rises and PV voltage and current increase, some VFD products will accept the input and when the power is high enough, it will start the pump. The PV array must be large enough to provide enough power to start the pump with including the head of water.
