Pump Inverter – Off-Grid Solar Installations – HydroController Solar


A range of inverters/variable frequency drives (VFD) for use with off-grid solar power systems. The HydroController Solar adjusts the speed of the pump to match demand, and the speed is varied (if necessary) to match the available power from the solar panels.

No battery storage is required. The HydroController Solar continuously uses all the available solar energy until the required system pressure is reached.
