Frecon Solar VFD is a device that use DC power from solar panel and convert it to AC power that supply to motor or pump, it adopted MPPT technology that ensures all the power that the solar panel generated can be supplied to the motor or pump.
Frecon Dry-run function can protect the solar VFD and the pump when the well doesn’t have water . this function can stops the pump once the tank have enough water as well. Our new technology of Dry-run function even can ensure our VSD detect dry-run (the pump running but no water in well) state without a sensor (only need detect the current by itself).
Frecon power shifting solar function can shift the power supply from solar power to grid power automatically if the solar power is not strong enough, this is a very useful and convenient function for many customers.
This technology enables Frecon solar VFD shift from solar power to grid power if the application is in somewhere that grid power is available and customers want ensure the solar pumping system runs all the time. Beside of that, It can shift back from grid power to solar power once the sunshine is back.
Frecon solar VFD is a perfect choose for solar pumping system because its features of low cost and easy to use (only need connect some solar panels and a pump)
