Solar Water Pump Battery System Design: Complete Guide

Solar-powered water pumping is one of the highest-impact applications for solar-battery systems in developing markets, providing reliable water supply for agriculture, livestock, and rural communities without grid access.

System Architecture

A solar water pump system consists of: solar panels → charge controller → battery bank → DC/AC pump controller → pump motor. The battery bank stores energy during peak sun hours for use during early morning and evening pumping cycles.

Sizing Methodology

Battery sizing follows three steps. First, determine daily water demand in litres. Second, calculate energy requirement using pump wattage and hours of operation. Third, apply depth of discharge constraint and temperature correction.

CHISEN Solar Water Pump Batteries

CHISEN offers a dedicated range of deep-cycle batteries rated for solar pumping applications, available in 12V, 24V, and 48V configurations with terminals and cable sets for straightforward installation.
