12v Dehumidifier

[AndrewPalmer]

My boat has a good array of solar panels but I tend to turn off the batteries at the main isolator when I leave to ensure no accidental discharge.
I would prefer however to set up a 12v dehumidifier on a timer and install a device to isolate the batteries automatically if they fall below a certain charge, which would also mean that I would also not need to worry about turning the batteries off. It seems a shame not to make use of some of the power I could be generating whilst the boat is left on its mooring and help the condition of the batteries by working them harder.

Does anyone else have experience of setting up something like this? Whic equipment to buy? One problem I notice so far is that the 12v timers tend to be the electronic type so if the battery isolates I guess it will zero unless there is a battery powered version.

to be of any value, a dehumidifier should be capable of gathering >5l of condensed water a day, and that is going to take a lot of 12v power.

Typically, a 350W dehumiddy will achieve 5 - 10l/day, and that means a 30 amp 12v line.

You are probably better off with lots and lots of ventilation.


To help with more detail, it would be handy to have tech info about your solar array, volume of the boat, and location.

I've no personal experience but what about a Fridgemate ?
