Macro Application 3 Phase Solar Pump Inverter With 99% Efficient MPPT And GPRS
1. Features of VEIKONG 3 phase solar pump inverter
1) Veikong VFD with nice ROI(return on investment) against diesel powered pumping, which means it's really economic in the long run.
2) Compact and uniform dirve module design which makes the whole device more reliabe when using it(protection level IP20 standard and IP54 optional)
3) Dual supplu capability with change over switch-solar and grid compatible. Thus when the solar is not strong enough, you can turn to the grid and make sure the whole system is still working.
4) Sensorless vector control of induction motors and permanet magnet motors for more markets.
5) Energy saving function and dry run self learning function
6) GPRS monitoring control lvia PC and mobile
