Solar Panels

[Snowbird]

Whatever amphour the batteries are rated at you can only use half of it or the batteries will die quickly as the volts will drop too low, 12v/240v/gas fridges should never be used on 12v or batteries will die even sooner, and that inverter will hammer them as well if used for any length of time.

I can just about do 3 days on my boat with no power input (I have no solar) but I spent a lot of cash on a efficient compressor fridge a couple of years back which helps and we spend most on the evening in the pub (to save the batteries...honest), we have 3x 100Ah batteries for domestic and a separate battery for engine starting, with pubs being shut for the foreseeable future I have just bought a 12v telly (I don't have an inverter) but may need to take a spare charged battery for that (not yet allowed to actually stop overnight so keeping away for now).

I do have the advantage of if moving I have 2 alternators running and water heating from the cooling system, of course on a boat you lug a lot more weight about, a 6 ton caravan wouldn't be very useful.
