Now, I DO have a deep cycle and solar setup, but I'm just nuts.
Hmm, nope...not nuts, just smart. It's not THAT complicated. It's way less complex than most people think. Time and patience required, sure.
Third option: go buy a small, ultra quiet gas generator. That is a plug and play solution.
Worst. Advice. Ever. Gas generators are obnoxious, I don't care how quiet they are. We can do better! Certainly not worth annoying your neighbors to run a few xmas lights. Get some LED strings with built in battery packs if you're going for quick and dirty. And I agree with gas for heating things. Much better use of energy.
