Product Overview

What This Product Is

A 15KW three-phase solar pump inverter system designed for continuous water pumping in off-grid or unstable-grid areas. It uses MPPT technology to maximise solar power extraction and automatically switches to AC grid or generator input when solar power is insufficient. The system includes the inverter, solar panels, mounting structure, and all necessary accessories for immediate commissioning. The inverter supports both solar and AC input, enabling 24-hour operation without manual intervention.

  • Power up the system and verify auto-switch function between solar and AC input
Quality Control

Checked Before Packing

Customisation

What Can Be Changed at Order Stage

  • Pump voltage and phase selected from single-phase 220V or three-phase 220V/380V
  • Boost module added for low-voltage operation in models 2.2kW and below
  • Solar panel count adjusted based on site irradiance and pump load

Comparison

How It Compares With the Alternatives

Grid-tie pump systemOperates without grid, but requires battery or generator backup during low solar
Diesel pump systemNo fuel cost or noise, but requires solar array and inverter for initial setup
Simple solar pump with no inverterNo auto-switch or protection, leading to pump damage during low sun or dry run
Single-phase inverter systemSupports three-phase pumps for higher power and efficiency, but requires three-phase input
Use Guide

Getting It Working on Site

1

Confirm the pump is three-phase 220V/380V and matches the inverter output

2

Install solar panels with uniform orientation and minimal shading

3

Connect the inverter to the pump motor and ensure correct phase sequence

4

Enable GPRS module and verify remote monitoring via APP

5

Test auto-switch function by blocking solar input and verifying AC backup activation

6

Keep the inverter cabinet clean and dry to maintain IP54 protection
