Waterboy 3HRH400 0.50kW Submersible Helical Rotor Solar Bore Pump Complete Kit with x4 140W Solar Panels

The WaterBoy 3HRH400 is the most powerful model in the 3” Helical Rotor solar pump series, delivering impressive performance for higher-lift applications. Engineered for reliable water delivery at heads up to 70 metres, it’s ideal for remote livestock watering, high-set tank filling, and off-grid pumping where strong vertical lift is required. This complete solar pump kit provides a daily output of up to 11,520 litres—making it a trusted solution for farmers and property owners seeking solar independence without sacrificing performance.

With a high-efficiency stainless steel pump, a 500W brushless DC motor, and an integrated MPPT controller, the 3HRH400 is built for the Australian outback. The system comes with 4 x 140W mono crystalline solar panels, 40 metres of prewired cabling, and either a bore cap or dam float depending on your installation. It’s a plug-and-play, low-maintenance setup designed to work where grid power can’t.
