I'm looking for small off-grid kits that include a battery for consistent output of about 1000 Watt Hrs per day, and are simple to install by myself

#3This is a great question, I hope we get some good answers in here. Cheap reliable off grid power set ups could provide a huge boost to everyone. Imagine moving to your new place, and just running a few panels up a pole right above the tree line.

#6You can make your own extremely easy.
1kWh is about 85 Amp Hours. You'll need at least a 160Ah battery if you don't want any extra storage. Usually you will need to at least double that for days when you don't have much sun. I would suggest you need at least 400Ah worth of batteries.
Then you have to figure out how much sun your panels are getting to determine if you can fully charge your batteries in that time for the rest of the day.
You'll most likely only need a few 100W panels. This means you'll be looking at Size? Well expect this entire thing to weigh around 500lbs!

I looked at them for RV use, though, and folks seem to be happy with them. Too rich for my blood, I ended up going with AGM for now.
Oh, and they have kits, too. Just add solar panels:

Wow. ~$1k/100ah for those babies. Dang.

Wonder how pricing compares with http://www.jouleboxpower.com/. The batteries seem to be the large cost in these energy storage solutions. Removing them and using hydrogen in propane tanks may reduce costs significantly.
