Product Description

Solar Pumping Inverter with MPPT

 

1.solar pumping system consists of 3 components:

1.solar panels

2.solar pump inverter

3.AC 3 phase 380V water pump

 

Solar Pumping System Introduction:

Sandi Solar pump system consists of the specialized pump inverter for PV, water pump and solar panels. This device widely used in domestic water, irrigation water, control of desert, animal husbandry, water supply for Sea Island, water treatment projects, etc. Water storage replaces battery and directly drives pumping, with high reliability, at the same time, it can reduce system cost and maintenance costs.

 

Product Features

1, Adopting the proposed dynamic VI maximum power point tracking (MPPT) control method & optimized SVPWM; fast response and stable operation; and the conversion efficiency achieves of 99.6%.

2, Adopting high-efficiency IPM (intelligent power module) from Mitsubishi with high reliability and high efficiency.

3, Designed with variable frequency driver (VFD), can be used in variable frequency speed regulation technology,greatly improves efficiency, and better to protect water pump and maximum utilization of solar panels.

4, LCD display operating panel, can setting various parameters through LCD, easy to operation.

5, Complete protection function for PV input under voltage, PV input over voltage, input connection Reverse Polarity, DC over current, output, over load, short circuit, dry Well, overflow, dry running, and blocking protection.
