I'm not 100% certain, but check the literature on Magnum Energy's Hybrid inverters. I do believe the bigger units have a dual input mode that allow you to run off a renewable source and supplement with grid power as needed. It doesn't back-feed the grid, instead it uses battery power (and power from the sun/wind), and only uses metered grid power when you demand more than your renewable source can provide.
Thanks, that was more about what I was thinking.
Because we live full time with a family in the Rv, dry camping kinda sucks. But I liked my 240w of power we had on the motor home (sold it), and I thought having solar again for when we do dry camp would be nice, then it would also be nice to be able to put it to use at the campground, even if the "break even" investment wasn't worth it.
