I want to build a 2-bedroom cottage in a remote area where sun is aplenty (Siem Reap region in Cambodia), but where I cannot count on a reliable utility company. Therefore, I need to put together a self-sustainable source of electricity (110V-50Hz) for the lighting, fridge and some electronic devices (TV, radio, computer, etc.). I estimate my needs to require at least a battery storage capacity of 3KW battery storage (looking at the newly-announced Tesla Powerwall, but a bank of gel deep cycle (200Ah) batteries could also do the job.

I need suggestions / answers immediately. Once I get the circuit to work from your guidance, I can award / pay. I am hoping to find a power expert that has seen and fought this fight before, not just anyone who is tossing out random suggestions (although I would take that now)
