Product Overview

What This Product Is

A solar pumping inverter system from 400W to 1800W designed to control and regulate solar water pumping operations. It converts DC power from the solar array into AC power and adjusts output frequency in real time based on solar radiation to perform maximum power point tracking (MPPT). The system includes a full aluminum alloy shell with IP52 protection, operates in ambient temperatures from -20℃ to +60℃, and supports pumps with high-efficiency permanent magnet DC brushless motors. The kit is delivered as a matched set with inverter, solar panels, mounting bracket, and optional battery, all packed in wooden boxes for export.

Quality Control

Checked Before Packing

Customisation

What Can Be Changed at Order Stage

  • Choose between 400W, 600W, 1200W or 1800W inverter models
  • Select solar panel type: mono, poly, blue, black, or PERC
  • Choose battery type: 2V/12V GEL/AGM or 48V lithium battery
  • Custom mounting structure designed with CAD drawings for roof or ground
  • Adjust output voltage to 24V, 36V, 48V or 110V AC based on pump requirement
Comparison

How It Compares With the Alternatives

Grid-powered water pumpNo grid connection required, but needs solar array and inverter for operation
Diesel-powered pumpNo fuel cost or logistics, but initial solar system cost is higher
Basic solar pump controllerIncludes MPPT and soft start, but basic controllers lack real-time frequency adjustment
AC inverter with no MPPTLess efficient under variable sunlight, but simpler and lower cost
Use Guide

Getting It Working on Site

1

Match the inverter model to the solar array’s max DC input voltage and MPP voltage range

2

Install the solar array so all panels receive uniform irradiance and shading is minimal

3

Connect the inverter to the pump using the correct AC output voltage and frequency

4

Install the water level switch if used to prevent dry running and overflow

5

Ensure the inverter is mounted in a ventilated, shaded area to avoid overheating

6

Check the pump and inverter operation regularly, especially after prolonged sun exposure
