Product Description

Fully automatic system using variable speed drive compatible with AC, *-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.
How does it work ?
An arrays of solar panels generates the power and voltage required for the SG**0/**0 solar inverter to drive the motor. The solar pump inverter converts the DC voltage to a *-phase AC output with variable voltage and frequency. The MPPT algorithm of solar pump inverter extracts maximum power available from the solar panels during the day and operates the motor at variable speed based on the power to the inverter. The frequency range in which the inverter operates depends upon the motor speed, hydraulic system and the power available from the solar panel. As the sunshine varies during the day, power to the inverter varies and generates variable V/F ratio thus controlling the speed of the motor, which in turn regulates the pump impeller speed. 
It is no need install battery for investment saving.
It is very suitable for **0VAC/**0VAC induction motor pumps and PMSM high efficiency pumps.
We also provide 1.5kw solor voltage booster to increase your solar panel voltage for saving solar panels invest.
