I have a so called duty 600WATT PURE SINE WAVE INVERTER off my battery bank. I went the simple way and run two extension cords from the 600WATT INVERTER with one multi-head receptacle going to the home entertainment area and the other multi-head receptacle going to the bedroom area. This is always ON when we are camping.
When I finally get my SOLAR PANELS installed they are only considered to just charge my batteries in high sun to keep me from having to run my 2KW Generator so much doing the morning re-charge of the batteries.
I went the baby steps way learning how to live off the batteries and how much capacity I really need to do our style of camping off the power grid.
Now that we are very successful now doing this I am ready to add solar panels to improve on it. Solar Panels and Generators here on the East side of the USA has to be considered differently than what the West Side of US folks have to deal with. We generally have less HIGH SUN and definitely have to deal with GENERATOR RUN TIME restrictions just about everywhere we go... Not that many DISPERSED camping areas near us...
