Expanding AC distribution panel

The 75 amp converter will pull approx. 1690VA from 120 input when doing 75 amps/14.x output. (that converter has PF of 0.73) So sharing a circuit with the fridge on electric is dubious. It would work if the converter were only doing regular 13.6v work at low amps output.

14.075 amps? I would need to ask how often is a 75 watt converter going to pull ~14 amps from AC when connect to no batteries and only used for 12 volt lighting and an absorption refrigerator?

If you ever go off-grid on whole house inverter, you want to shut off the converter and have the fridge on gas, so that would be easy if they shared. OTOH if the converter has its own breaker it is easy and you can just unplug the fridge 120 outside if it won't stay on gas by itself instead of auto to 120.

If I were to go off-grid for an extended length of time (months or longer) because of the climates where I'm at there would be little or no solar and I would mainly use a genny and most likely have a battery bank to maintain for off-grid. So the genny would be used part time for AC and to maintain a battery bank. I'm not certain if I would want to rely on a battery bank and inverter when compared to a genny

With the 7300 converter sharing with receptacles and you want the receptacles to stay live, you can insert a switch on the converter's black wire on its way to the breaker before where it joins the receptacles' black wire at the breaker.

The MW/WH one or the other switch (like in our 5er) trick can be used with anything that shares. Just means "power management" by the "operator". Lots of that when RVing anyway when using high draw appliances (shut off fridge 120 for a couple minutes while making toast eg) if on limited shore power. The more you do that, the fewer extra breakers needed.

I have a couple of modified sine wave inverters an Xantrex 1750 plus and a Trip-Lite PV2000FC is described as PWM sine wave. However for off grid true sine wave inverters are preferred and more efficient.

When I go off-grid in the past it's been mainly in the wilderness, so I more or less camp out and use the frig to preserve food. It's better than using a tent as you have a toilet, running, water, gas catalytic heater, etc. However I have several canvas tents I sometimes used as the RV can't really go off-road same as a Jeep. Though some RVers do get back in the woods quite a ways ans will stay out the entire summer in wilderness areas. Hunters use RV off-road in the winter months. I often go past their camps in up to a few feet of snow when it's very cold out. They set of hunting camps that are comprised of tents and rvs. Often they have large tarps where they have fires going for keeping warm, cooking etc. One problem with some RVs is there not rugged enough for off-road use unless they've been modified as are some 4x4 motorhomes that can go nearly anywhere and built for off-road use.
