What is a VEICHI Solar Drive?

What is a Solar Drive?

Solar drives (solar inverters) convert DC energy generated by solar panels into AC power required by pump motors while also controlling motor operation.

In agricultural irrigation systems, a solar drive is responsible for:

* Operating the motor at optimal frequency

* Tracking maximum power point (MPPT)

* Protecting the system against voltage fluctuations

* Preventing dry run, overcurrent and phase errors

Incorrect drive selection reduces system efficiency and shortens equipment lifespan.
