Common questions
- How much power does the Rainman Modular 48VDC 140L use?
- It draws 1,250 W and makes 100–140 L/hr, which works out to 10.4 watt-hours per litre. Making 100 litres — four people at 25 litres a head — costs about 1,042 Wh, or roughly 87 amp-hours from a 12 V bank.
- How long does the Modular 48VDC 140L take to make a day's water?
- At its rated 100–140 L/hr, 100 litres takes about 0.8 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 48VDC 140L cost in Australia?
- Our indicative figure is $6,421, 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 48VDC 140L 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 48VDC 140L efficient?
- It ranks 18 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.
