We are about to set off for Europe for a couple of months. We usually take 2 x 13kg lpg but can't get any at the moment. So, have decided to change the fridge from a 3-way to compressor all 12v electric. I've ordered an Isotherm 85. The blurb says it uses 368w per 24 hours. I don't know how to work out if the 135 solar panel and the 150 battery will handle it. Any advice please?
