Looking at options to build a system for power outages during hurricanes that will run a 5000 btu window AC, small fridge and charge cellphones and tablets. Originally was thinking maybe a delta 2 max with 4 200 watt panels... would that be enough to run a small AC through the night? another option is using 35v/ 200w used panels which I can buy as many as I need locally for $50 each but it seems the delta 2 max wouldn't be able to handle 4 of those because of the voltage so looking for suggestions on a system I could build that would utilize those panels. Thanks!
