The Waterboy 3HR300 is a robust mid-range solar pumping system designed to provide reliable water supply for small to medium-scale rural and off-grid applications. With pumping capability up to 60m total dynamic head (TDH) and daily output of up to 11,160 litres, it is suited to stock watering, tank filling and remote water supply from bores or dams.

The complete system combines a 3" stainless steel helical rotor pump, brushless DC motor and integrated MPPT controller with three 140W monocrystalline solar panels. Soft-start technology, adjustable speed control and low-water protection help provide efficient and reliable operation without requiring a grid connection.
