How Solar Pump Variable Frequency Drive is Different from Solar Pump Inverter

The Solar pump variable frequency drive (VFD) is an integral part of electric components across industries. Also called as AC drive, VFD electricity is supplied by gird or generator directly; it means standard VFD is either using AC power, 3PH or 1PH. Solar pump VFD gets input from PV module and change it to AC output for pump controlling and pump functioning.

Hardware is 100% same as regular VFD, the difference between typical VFD and solar pump controller is of MPPT Algorithm SOFTWARE. It can be said Solar Pump VFD is VFD based MPPT pump controller. VFD doesn’t have specific MPPT control unit. It can be obtained by customized software without any hardware substitute.

A solar inverter converts the DC (Direct Current) output of a PV solar panel into a utility frequency AC (alternating current) that can be fed into a commercial electrical grid (or) used by a local, off-line electrical n/w. Solar pumping inverter acquires the electricity directly from PV module and transfers it to AC for pump controlling and other functioning. Its formidable MPPR control card inside ensures system’s energy reliability and efficiency. This upgraded technology is based on the solar inverter and adding more needed hardware for optimizing water pump control solution. There is special individual MPPT control unit inside. It is easy to install and doesn’t need much maintenance. Ingress Protection level is similar to international solar inverter standard.

Few advantages of high-frequency solar inverter:

When buying variable frequency drive from trustworthy VFD drive manufacturers, it's necessary to pay attention to its application. When distinguishing a VFD to run a motor, a buyer requires considering the application, the motor nameplate data, how it is being monitored and the environment in which it will be operating. It should have the potential of bearing the overload of specific applications. There are several reasons to ensure that you have the correct overload rating on your VFD. Sizing too big might produce added costs and perhaps even end up damaging the motor. If you do not want to face any worst case scenarios, then consider these points.

In the above article, the author has written about the solar pump controller and high-frequency solar pumo inverter. She has also written about the thing you need to consider before buying a VFD drive from a relibale VFD drive manufacturers.
