hey, similar question from me,
we have a dometic CRX50 fridge, 110A leisure battery. the fridge states 3.6A usage on 12V. so that means if the fridge is constantly running for 24 hours it would use 86A, and drain the leisure battery .
The only other things we'll be using from the leisure battery would be the LED lights, tap (~2-3 minutes a day) and the usb sockets to charge phones.
Based on this, we were looking at 150W panels, I calculated that should add about 90A a day? So would take a whle to drain, ie far longer than a full weekend, and if we were away longer I'm sure we'd drive somewhere at least once that would top it up.
Does that sound about right, or would more / much less be required?
