Looking at new 5th wheel. we want a fridge that is gas and electric. Sales is trying to talk us into a residental fridge (electric only). he wants to install 2 400 watt panels and a 1500 watt inverter. Claims with 5 hrs of sunlight daily that it will run my fridge 24/7. WILL IT ?? any opinions or teck advise would be really helpful.... Thanks Xglassman going fulltime.
