Hi

I've been looking at a few meets that are EHU-free, and as i like my luxuries and hate warm beer, i was wondering how long would i be able to run my 90W beer fridge off my 85Ah leisure battery through an inverter.

The battery is only 18 months old and doesn't lose charge over winter, it's was remover from my van when i traded it in.

What size inverter am i best off getting, one just big enough for the job (or is this liable to overheat) or the biggest i can afford (is bigger more efficient).

I usually do weekend meets, so 48hrs would do before a recherge is needed.

Am i dreaming or is this a possibility.

  Anythings possible, but this is unlikely to work for two days,.  Everytime you open the door you let heat in.

 how do you plan to charge the battery on site.?

If that's a proper fridge (compressor) then an invertor rated at 150w is not going to run it. The start up on a compressor requires a much bigger invertor.

even if its a peltier fridge and the 90w is the max, at 7.5 amps if you get 5 hours out of the battery you will be doing extremely well.

There is a bus out there with 10 x 110 Ah batteries and a full domestic fridge, that could be run all week just from the batteries, depends how much you want to spend and carry...

Hi Teardrop

Yes it is a compressor fridge, i did know about the start-up surge, but i presumed inverters were rated continuously (and could handle the surge).

Hmmmmm.............. 10 x 110Ah batteries, NOT......LOL
