How it Works?

Solar pumping system offer smarter and viable ways to deliver reliable water supply for farm, households, Schools and Communities. In addition to reducing energy costs to zero, operating costs are also extremely low. This, ultimately, is what keeps the solar pumping solution economically sustainable and in operation long term.

MPPT/PID-algorithm

MPPT algorithm for submersible pump , PID algorithm for surface pump.

MPPT algorithm

Hober Technology MPPT multi criteria method is a patent algorithm of dynamic VI maximum power point tracking, which has fast response speed and good operation stability. It can make full use of solar energy to solve the problem of poor tracking effect and unstable operation of the traditional MPPT method when the sunlight intensity changes rapidly, even causing water hammer danger, and prolonging the service life of the system.

PID  algorithm 

The controller’s PID algorithm restores the measured speed to the desired speed with minimal delay and overshoot by increasing the power output of the engine.

Hybrid DC and AC input , solar priority

Solar power and AC power hybrid input at the same time , and the solar power is priority. When the solar power insufficient, AC power will be supplement rest power automatically , and inverter shows hybrid on; when the solar power recovery, the inverter will automatically only take power from solar power, and LCD screen shows hybrid off..

The hybrid function is to solve the situations that solar power insufficient or no output in the early morning, evening and rainy days, but required the pump output rated water.

Solar pump inverter protection

The best protection of solar pumping inverter by ARM cpu: Solar input + ,- reverse input,  ac output wire disconnect/ pump  disconnect, pump coil or Pump Wire short Circuit, Pump Over Current (blocked running or Check value stopped by hurge pressure)or Over Rated Power of Inverter,  no water input to the pump(pump dry run), Solar low power output at morning and Evening .,etc

Comprehensive Protections:

Soft start

DC Input Anti-reverse

AC Input/Output Phase lost(3Phase)

AC Output Short Circuit

AC Output Unbalance (3Phase)

Pump Dry run protection By sensor/ software

Water Over Flow of Tank

Solar Low power

Over Load

AC Output Over Current
