Pure sine wave inverters. 12v /230v

Quite frankly its a bizarre solution for a problem that i solved over 30 years ago. I had Motorhome, needed 240V for phone chargers, nice TV, sat receiver and playstation, so wired an inverter, as you do, BUT it was terminated to a dedicated double socket where all the above were located and next to a double socket which would be powered under hook up conditions. All i needed to do was unplug the stuff from inverter socket to hook up socket. Terminating on a plug and then backfeeding the whole electrical installation was simply not necessary so i do not understand what problem is trying to be solved here.

If the OP was serious, neither do I. Or rather, it's a common problem with a very simple solution - a 3-position DP transfer switch. The OP claimed there was no room for the switch and I appreciate that not every motorhome has a conveniently located engine room like my boat (where my ATS is). OTOH I presume there was still some space at the morgue.
