Product Overview

What This Product Is

A 1100W solar DC water pumping system with a permanent magnet brushless pump and a PM solar pumping inverter. The inverter uses a patented dynamic VI MPPT algorithm for fast response and up to 99% MPPT efficiency, with a maximum 98% conversion efficiency. The pump features a rare earth permanent magnet motor without excitation coil or current, delivering higher efficiency and lighter weight than equivalent asynchronous motors. The system supports optional helical rotor for high lift or centrifugal pump for high flow. It includes an installment encryption function for financing. The system is designed for off-grid water supply with a water head of 17 to 25 meters and daily flow of 40 to 70 cubic meters.

Comparison

How It Compares With the Alternatives

AC solar pumping systemNo need for grid or diesel backup, but requires a DC pump and compatible inverter
Diesel-powered pumpNo fuel cost or noise, but requires solar panels and initial system setup
Standard asynchronous motor pumpHigher efficiency and lighter weight, but more complex control and higher initial cost
Grid-tie solar systemWorks without grid, but requires battery or pump storage for off-grid operation
Use Guide

Getting It Working on Site

1

Determine daily water requirement and required lift height before selecting pump type

2

Install solar panels to face south with minimal shading and tilt angle matching latitude

3

Connect PV array to inverter input with correct polarity and ensure MPP voltage within 120–160V

4

Submerge the pump in the well or water source and ensure the outlet is properly sealed

5

Test the system with full solar input to confirm MPPT tracking and pump operation

6

Monitor pump performance and check for blockages or debris in the intake regularly
