Description

The Nastec Solar Inverter is able to convert DC voltage coming from solar panels into AC voltage for powering any pump driven by a three-phase motor.
Pump speed is constantly adapted to available solar irradiation thus maximising the amount of pumped water and making possible operation even in conditions of low sunlight.
The device also offers complete pump protection against surges, overloads and dry running.
Change your existing Three Phase pumping system into a solar powered pump system.
