Waterboy 3HRH400 Submersible Helical Solar Bore Pump Kit with 4x Solar Panels & 40m Cable

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.
