I did this when I lived on my sailboat in San Diego and it worked GREAT! 1200 watt inverter with a charge control/monitor and two 75 watt panels with six,6 volt golf cart batteries.On my westy only one panel. One more panel just adds more amp charge. I have one deep cycle marine under the bunk with one 75 watt panel,two would be better but no room. This will run a coffee maker or toaster. Now I just need to find a very small, low wattage draw microwave and then you have instant junk food.My rear heater core was leaking so I got rid of it and that's where I placed the inverter.
