A submersible bore pump sits down the hole and pushes water up to a header tank or straight into a pressure system. Deeper bores need bigger pumps, and those have a hefty start-up surge. A small generator often struggles to start them, which is why so many people find their backup plan does not actually work the first time they need it. When it fails, the house has no water and the stock troughs empty too.
The battery and 15 kW hybrid inverter are designed to supply start-up surges with headroom for peaks, then the steady running load. With UPS mode there is no gap at all, so the pump keeps running through a grid failure and does not hit a low-water cut-out on restart. Most household bore pumps sit well within the system's output. Very deep bores with large pumps, or a bore that also feeds irrigation, would be checked in pilot sizing.
How it works →
The electrolyser needs filtered, de-ionised water, about 9 litres per kilogram of hydrogen, and treatment is part of the system. Bore water with high iron, hardness or other minerals will need that treatment to work properly, which pilot planning would test. The fuel cell gives most of the water back, so the bore's extra load is small. Round-trip efficiency is 30% or less, so it is a reliability system, not cheaper pumping.
The battery and 15 kW inverter are designed to handle start-up surges with headroom. Most household bore pumps fit well. Large or very deep pumps would be checked in pilot sizing before installation.
The electrolyser uses filtered, de-ionised water, and treatment is part of the system. Bore water quality would be tested during pilot planning to make sure treatment suits it. The fuel cell returns most of the water it uses to the loop.
A small garden or stock supply may fit. Large irrigation pumps can be too big for 15 kW alongside a house and may need a larger or multi-unit setup, or may not be a fit.
