So as I've said in past been looking, researching this RV solar. This is what I'm going to do. 1st, 12v system, 24 volt waste money on rv, they are meant for residential sending power back to electrical grid. 4 6volt batteries and 4 160 watt panels. Magnus MS2012 2,000 pure sine inverter, Magnus remote MARC50 remote, magnus battery maintain kit, Trace C40 Controller, 4 Carmanah 160 watt solar panels. Tilt-able solar panel brackets (45°). On something like this I'm not DIY. So total with installation is $4163.
