Nastec MIDA Solar Pump Inverter
A compact solar pump inverter for single-phase and three-phase pumps up to 4 kW. Use it for a new solar system, or to convert a pump you already own to run on solar power.
Why choose the MIDA Solar
Convert your existing pump
Runs standard single-phase and three-phase pumps from solar, with no start capacitors or relays needed.
Fewer panels
Automatic voltage boost means your solar array is sized to the pump's power, not its voltage. That can mean fewer panels.
MPPT
Pump speed and flow follow the available sunlight to get the most from your panels.
Built for tough conditions
IP66 rated enclosure, suited to humid and dusty sites. Works from -10°C to 60°C.
Full protection
Protects your pump against over and under voltage, overcurrent, dry running and overheating.
Set up from your phone
Program and update it with the Nastec NOW app over Bluetooth. Optional remote monitoring with email alerts.
Solar by day, backup when you need it
The MIDA Solar MP version can run on solar or on mains or generator power. Pair it with the Nastec HMA and it switches between sources automatically, so your pump keeps running on cloudy days.
For bigger systems, several smaller pumps can run in parallel, each with its own MIDA Solar. That gives you backup if one pump needs servicing, and keeps water moving in low light.
