1,Specification

The HSPL/HXXXXL/HA/B series products are convert the DC output of the PV array to AC and drives the pump, according to the PV array output power (caused by sunshine intensity change) regulates output frequency to achieve the maximum power point tracking. 

Solar pumping system is composed by Solar array, the equipment, and pump ,it is mainly used for agricultural irrigation, desertification control, grassland animal husbandry, city water, living water and other fields; with low carbon, energy saving, play an active role in improve the water shortage area people's living standard and the ecological environment.

2. Performance characteristics

1.          applies to the use of three-phase asynchronous motor pump;

2.          with maximum power point tracking algorithm for dynamic VI, fast response speed, good stability, the efficiency of MPPT 99%;

3.          fully automatic operation, can according to the actual situation to set free the speed range of pumps

4.          using efficient SVPWM algorithm, the main circuit and high reliability, the highest conversion efficiency up to 98% ;

5.          intelligent recognition of input voltage range, without the need to manually adjust the open circuit voltage, maximum power point voltage

6.          no button set to run automatically, only a switch control stop and boot;

7.          the maximum flow support manually controlled, prevent  stop and boot repeatedly when water less or less needs of water

8.          The function of protecting the motor complete, can choose the upper and lower water level monitoring and control circuit, to prevent dry or over flow's pumping;

9.          aluminum alloy shell, protection grade IP52, use environment temperature: -20 ℃ ~ +50 ℃;

10.       allows a wide range of input voltage, L type 200-450Vdc, H type of 460-750V

11.       with over-voltage, over-current, over temperature protection

12.       input anti reverse function

13.       small size and lower weight
