What it costs to run
A four-person crew using 25 litres a head needs 100 litres a day. On this system that is:
1.5 hrun time per day
1,825 Whenergy per day
1.1×400 W panel-days
$66per L/hr of capacity
This is an AC system, so it needs a generator, shore power or a large inverter. The Wh figure is what the generator has to cover.
Where it sits in the market
Ranked 28 of 30 rated systems on watt-hours per litre, where lower is better.
A conventional high-pressure pump with limited membrane area, so each litre costs comparatively more energy. Fine on a generator, expensive on a battery bank. How the two technologies differ →

Common questions
- How much power does the Rainman Modular AC 75L use?
- It draws 1,250 W and makes 55–82 L/hr, which works out to 18.2 watt-hours per litre. Making 100 litres — four people at 25 litres a head — costs about 1,825 Wh.
- How long does the Modular AC 75L take to make a day's water?
- At its rated 55–82 L/hr, 100 litres takes about 1.5 hours. Output falls in cold or silty water, so treat that as a best case rather than a promise for every anchorage.
- How much does the Rainman Modular AC 75L cost in Australia?
- Our indicative figure is $4,522, taken from the manufacturer's published US list and excluding freight, duty and installation. Australian dealer pricing is usually all-inclusive and reads higher. Ask a stockist for a landed AUD quote before you budget.
- Who sells the Rainman Modular AC 75L in Australia?
- 20 verified Australian businesses are listed as Rainman dealers or specialists, including Rainman Desalination, The Watermaker Man, M Water Marine & RV. Each entry links to the manufacturer or company page that proves it.
- Is the Modular AC 75L efficient?
- It ranks 28 of 30 rated systems in our table on watt-hours per litre, where lower is better. The best in the table is 3.7 Wh/L. It uses a conventional high-pressure pump, which is the main reason it sits above the energy-recovery systems.
