Solar Pumping System consists of 3 main parts, PV Module, PV Pump Inverter, and Pump.

The Pump Inverter converts DC Power generated by the Solar panel into AC Power required by the pump. A DSP inside continuously monitors available energy levels and adjusts pump speed, matching energy required to energy available. This enables the system to operate under varying solar insolation levels, and provide water throughout the day and through different seasons. Our CEHE Inverter also utilizes a high efficiency MPPT algorithm to maximize power harvested from the solar PV panels.
The output of our Solar Pumping Inverter have two different kinds:
1. L series: 3 phase, 220V~240VAC, 50Hz/60Hz;
2. H series: 3 phase, 380V~460VAC, 50Hz.

More features, different from common Off-grid PV Inverter:
1. MPP tracking, with wide range, Static & Dynamic MPPT control;
2. DC-AC conversion to drive 3 phase AC pump;
3. Variable Frequency Drive to match speed of pump to available power;
4. Full set of protection mechanism, lengthen the lifespan, 15-20 years;
5. Auto/Manual settable start-stop model;
6. LED screen for fault and status display;
7. IP65 for outdoor use, with anti-thief design;
8. Remote monitoring and communication function.

A. Sensor-less dry run protection;
B. Short-circuit protection;
C. Phase lose protection;
