CAUTION!!!
All good comments from everyone. The bottom line is: 1) There has to be a way to insure that when your brother-in-law connects the shore power while the inverter is on the inverter automaticaly disconnects itself. Some inverters do this internally, some do not and need an AC interupt switch. 2) There needs to be circut protection. 3) There are circuts that you do not want to energize when the inverter is powering the circut. AKA water heater, battery charger and other BIG power users. There needs to be some positive way to keep these circuts from being energized when the inverter is powering the circut. Leaving it up to your brouther-in-law to figure out which circut breakers to turn on/off to keep from blowing the inveter or killing your batteries is not a solution I'd recommend to anyone. My Hunter 37.5 has an AC interupt switch and two seperate circut breakers (dbl poll) that control the inverter and the shore power supplies that physically cannot both be on or off at the same time. These circut breakers also control the water heater and battery charger circuts so that when the inverter is powering the system those circuts do not receive power. It is complex electricaly but simple for the user. You can't get bad things to happen no matter how hard you try. The worst that can happen is the circut does not get power. My brouther-in-law figured it out on his first try.
