Solar Water Pumping Solution is a fully automatic system designed to provide water at affordable cost for people with limited or no access to electricity. It uses the most advanced SG300/320 variable speed drive to regulate the speed of a 3-phase AC motor depending upon the solar energy available from the solar panel.


Fully automatic system using variable speed drive compatible with AC, 1 /3-phase, submersible and surface mount pumps, and high efficiency PMSM Pumps.

The system is composed of a PV generator, a pump and a solar pump drive. Based on the design philosophy that it is more efficient to store water rather than electricity, there is no energy storing device such as storage battery in the system. The system is prepared to be combined with a elevated water storage, e.g. water tower or an uphill tank installation.


Advantages of SG600 solar pump inverter

♢ Maximum power point tracking (MPPT) with fast response speed and stable operation

♢ Enable to drive for 1 phase AC pumps or 3 phase AC pumps

♢ Enable to drive for PMSM high speed and high efficiency pumps without motor ID auto tuning

♢ Dry run (under load ) protection, lowest speed auto tuning , Pumps maximum current protection, Minimum power input protection...

♢ The PQ (power/flow) performance curve enables to calculate the flow output from the pump

♢ Dual mode AC and DC power supply input is available

♢ Digital signal of water level sensor and analog signal of water level sensor for water tank fulling detect.

♢ Dedicated hardware design with dual CPU, independent air duct design

♢ Import IGBT module such as Infineon, Fuji,TYCO to ensure good quality

♢ Enhanced lightning protection module

♢ GPRS remote control module for distance monitoring, control, parameters modification, and history data record..

♢ Efficiency is higher than 99.6%, power factory not less than 0.96 for below 15kw inverter.
