Common questions
- How many 240 V AC watermakers are sold in Australia?
- We currently table 12 240 V AC systems, the most efficient being the Rainman Portable AC 140L at 9.8 watt-hours per litre. The list grows as we verify more brands.
- What size 240 V AC watermaker do I need?
- Start from daily litres, not boat length. Four people at 25 litres a head is 100 litres a day. Divide by a candidate's rated output for run time, and multiply by its Wh per litre for the energy it takes out of your day. Our sizing calculator does both against your own battery bank.
- Will a 240 V AC watermaker flatten my batteries?
- Only if you run it off an inverter without the engine or generator going. These systems draw 1,250 W and up, so they are designed around a genset or shore power.
