What it costs to run

A four-person crew using 25 litres a head needs 100 litres a day. On this system that is:

0.8 hrun time per day
984 Whenergy per day
0.6×400 W panel-days
$43per 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.

Common questions

How much power does the Rainman Modular AC 140L use?
It draws 1,250 W and makes 100–154 L/hr, which works out to 9.8 watt-hours per litre. Making 100 litres — four people at 25 litres a head — costs about 984 Wh.
How long does the Modular AC 140L take to make a day's water?
At its rated 100–154 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 AC 140L cost in Australia?

Is the Modular AC 140L efficient?
It ranks 12 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.
