solar power for dry camping & cpap machine

And a PITA at 3am in the morning when you suddenly lose campsite power and have to go outside in your jammies to unplug the main service cable from the now dead campsite post and plug it into the inverter. The better solution is to either hardwire the inverter through an automatic transfer switch OR not run the inverter "whole house" at all and instead install a few dedicated receptacles inside the camper that are fed directly by the inverter. I did, and now when I lose power in the middle of the night all I have to do is roll over in bed and hit the inverter's remote switch to activate the duplex receptacles it feeds.

YES
But he wants this for dry camping, which means no shore power to lose at 3 A.M.

Being inverter, even with shore power is a safety, no problem if shore power drops out
But not the op question
