What to ask them
- What daily litres are you sizing this for, and from what assumption?If the number is not written down, it is not a design. Ask what crew and per-person figure it came from.
- What is the Wh per litre at my voltage, from the rated draw?It is output divided into draw and no brand prints it. A designer who cannot answer is quoting a box, not a system.
- Will this run off solar, or does it need the engine or genset?It changes the boat you end up with. Run it against your own array before agreeing to anything.
- How much does output fall in warm or brackish water?Rated output is at a stated temperature and salinity. Northern Australian water in summer is neither.
What sizing and system design involves
Daily litres, honestly
Crew multiplied by realistic consumption, not the worst week you ever had. Oversizing costs money twice — once at purchase and again in the energy a bigger pump draws every run.
The voltage decision
Voltage does not change efficiency, but it changes what your boat can run without starting something. A 12 V system on a 12 V bank is simpler than a 240 V unit that only lives when the genset does.
The power budget
The number that decides everything: watt-hours per litre times daily litres, against what your solar and bank can spare after the fridge. This is the calculation the whole comparison table exists to make possible.
Space and integration
Modular systems fit around obstructions where a single-frame unit will not. Whether it shares a seacock, how the brine leaves, and where the noise ends up are all design decisions, not install details.

Keep looking
Local means local. A business is listed here when its workshop address or its own stated coverage names this area and its listing claims sizing and system design. Australia-wide suppliers are shown separately and never presented as local. This page exists because two or more providers meet both tests in Sydney and Pittwater; where only one does, the region page is the better answer and no page like this is generated.
