1.Adopt MPPT control method, with fast response and good stability; no destructive water hammer effect will be caused due to poor tracking, unstable operation or fast changes of light intensity;

2. Applicable to all of pump driven by the three-phase asynchronous motor pumps;

3 Wide voltage range design;

4 Automatic frequency conversion control;

5 With protections against overvoltage,undervoltage,overcurrent, and overload;

6.Prevent to pump all the well water out , and prevent to overflow the tank water.

7. DC power supply input for solar panel, or AC power supply inputs for grid ,diesel generator and inverter etc. For any power source input.
