Hi,
Whether you are a flower child or not, if you're searching for plans then google is your best friend, e.g.:

Have never built these so can't guarantee they'll work, but I intend to build the first one some day.
There are much more plans around on the net for solar chargers.
Building an inverter? You must be really ambitious. I don't think I'll bother with it. Plenty of cheap 2nd hand UPS-es around that will do the trick. Store-bought inverters are much cheaper than just buying parts for a DIY project.
There are plans on the net for simple inverters too (two big 2n3055s and a transformer), but I wouldn't connect my expensive electronics to one of these. Your situation/opinion may differ.
Peter.
