My application is a Mobile 20 foot travel trailer that I will travel & l live in full time. I would like to run everything on battery, re-charged by solar Photo Voltaic cells. I will have a generator (Honda EU2000i) for back up. I will have a fixed, non-expandable physical space for the battery bank in the trailer. The wire run between battery bank and 3000 watt inverter will be less than a foot long and wires from solar panels to the battery will be relatively short also, but the longest less than 15 feet long.
Short wire runs from the battery bank to the inverter is a BIG WIN ! Stick with a 12V battery bank, but I would go UP one wire size just for peace of mind.
Depending on how many hours a day you are running in the A/C off of the battery bank will be the deciding factor on how many solar panels you will need. That and the "fixed, non-expandable physical space for the battery bank". You may only get a couple of hours (at best) of A/C usage after the sun goes down !
Check into getting a "soft start" for the A/C.
The restricted battery bank space is likely going to kill all of your plans.
