Whether you’re installing a solar inverter for a 10 hp water pump, a vfd solar pump for commercial irrigation, or a 3 phase solar water pump on a livestock ranch, the Hober 7.5kW handles it all.
☀️ More Water from the Same Sun
With its advanced MPPT controller, this mppt solar pump inverter pulls maximum power even when panels are shaded, dirty, or poorly oriented.
According to the NREL, solar MPPT systems produce up to 30% more output compared to fixed-input setups.
Result? Earlier starts, later stops, and more water pumped—every single day.
🌀 Smart Pumping with Integrated VFD
Instead of simple ON/OFF behavior, the VFD for solar pump function ramps the motor speed up gradually, preventing pressure shocks (water hammer), extending pump lifespan, and enabling flow adjustment on the fly.
-
Ideal for high-head systems and long pipe runs
-
Compatible with all standard 3-phase AC water pumps
-
Allows variable output even during cloudy weather
🔌 Solar + AC = Zero Downtime
The hybrid solar pump inverter mode gives you uninterrupted operation:
-
Use solar energy as the primary source
-
Automatically fall back to grid or generator
-
Return to solar once sunlight returns
-
No manual switching needed
You’ll never have to pause watering because clouds rolled in or night fell.
