2.2kw solar water pumping system without battery for agriculture irrigation

1. Water pump is driven by three-phase AC motor;

2. It adopts dynamic VI maximum power point tracking(MPPT) and optimizes pure sine wave PWM control ,with fast response speed, good stability;

3. Full automatic operation, according to the actual conditions,it can freely set the range of pump speed ;

4. The main circuit uses digital power module,with high reliability, high conversion efficiency of *8%;

5. Have complete electrical protective function, it can choose water level detection and control circuit, to prevent overflow and dry well;

6.Protection grade IP*1, working environment temperature: **0°C ~ + *0°C.

7.No need bettery(water storage replaces battery power storage)

8.Starting box is not required

9. LCD display, simple operation. setting parameters and fault detection

*0.Low voltage drive function( LV****0 special DC - DC converter converts *9V***0V to **0V***0V to drive solar pump system,which reduce the cost of solar panels and danger of DC high voltage)

*1.AC drive fuction.(when sunshine is not enough ,AC city power is switched to work manually)
