I don't know a lot about these things, and a lot of the stuff I've been looking at on the web is so wide and varied it's getting a bit confusing. I would like a system just big enough to power my furnace & fridge plus maybe a few lights if the power goes out for more than a couple hours up to a couple days, I'm thinking in the 1.5 - 2Kw range. I would like one of those all in one kits so that a guy that grew up in the lego generation can just follow the simple directions and snap parts together and plug stuff in. It look like I could get better stuff cheaper by buying pieces separately but then I'm afraid I'd be lost trying to get it all put together. Anyone recommend a system or know of the best parts to try and put together that are fairly simple to install?
