Waterboy 3HR200 0.50kW Submersible Helical Rotor Solar Bore Pump Complete Kit with 140W x2 Solar Panels

The WaterBoy 3HR200 is a premium entry-level solar-powered submersible pumping system, purpose-built for rural and off-grid water supply applications where reliability, simplicity, and energy efficiency are essential. Designed and manufactured by a trusted Australian family business, this 3” helical rotor pump is powered by a highly efficient brushless DC motor and intelligent MPPT controller, making it capable of lifting water up to 30 metres vertically with flow rates of up to 6,120 litres per day. 

Despite its compact size, the 3HR200 delivers outstanding performance for small-scale tank filling, livestock watering, or domestic garden irrigation. Whether you're replacing a windmill, upgrading an old diesel system, or installing a new water source in a remote area, the 3HR200 offers a plug-and-play solar solution that’s easy to install, operates silently, and requires no ongoing maintenance. It’s a reliable, self-sufficient system designed to work straight out of the box—even in tough Australian conditions.
