Waterboy 4C48400 0.40kW Submersible Centrifugal Solar Bore Pump Complete Kit with x4 140W Solar Panels

The WaterBoy 4C48400 is the most compact centrifugal solar pump system in the WaterBoy lineup, purpose-built for smaller rural, domestic, or agricultural water supply needs. With a lift range up to 20 metres and a maximum daily output of 15,120 litres, this 4” centrifugal system is ideal for shallow bores, tank filling, or transferring water from dams and holding tanks—especially where high pressure isn’t required.

Powered by a 0.40kW brushless DC motor with built-in MPPT controller, this plug-and-play solar pump kit includes four 140W mono crystalline solar panels (560W total), a cyclone-rated array frame, 40 metres of cabling, and your choice of bore cap or dam float. Simple to install and highly efficient, the 4C48400 offers quiet, low-maintenance operation and delivers water wherever the sun shines.
