To create more value for customers is our business philosophy; customer growing is our working chase for 28 Years Factory Surge protective devices-SPD for America Importers, With superb service and quality, and an enterprise of foreign trade featuring validity and competitiveness, that will be trusted and welcomed by its clients and creates happiness to its employees.
- The Surge protective devices(SPDs), suitable for residential,commercial and industrial appications, are designed to limit transient overvoltage and run-off lightning currents.
- It provides reliable protection from the destructive effects of lightning and switching
- are lightning current arrsters, they can handle and divert high energy from lightning.
-they are necessary when the installation is exposed to direct lightning(for example when the buiding is equipped with external lightning protection system or powered by aerial lines).

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.
