First time posting answer .I am setting up a solar backup system to backfeed my home during power outages or emergencies. Of course I have to have the main breaker turned off to prevent backfeed to the grid, but is there a switch/relay I could install between my electric panel and my inverter to prevent accidental backfeed voltage damaging my inverter? My system is attached to a subpanel out in my barn. I want to make it idiot proof for the wife and teenage kids to be able to turn on if I am not home. With not being located at the main panel, a typical transfer bar system won’t work. I have seen magnetic relay systems in the past. What is the name of the switch that I need to install between the inverter and my subpanel? Of course there is the breaker in the subpanel connected to the inverter that would need to be switched on/off but I want to have additional safety features to not damage the inverter in case somebody does not follow the directions properly.
Thanks

Your thinking is off just a little. My answer . Leave maine panel alone. Do not try to switch 200amp sevice. [ ats ] instead pull from main panel 50a double pull breaker . To 6000w or larger. inverter with pass through. from inverter, Feed sub panel with a 25a double maine breaker 25a L1 25a L2 . Put all lights, frige, plugs of house. Keeping all large , high wattage items on maine. Barn same thing. In doing so everything is powered by mains through pass-through of inverter. If power goes out mains off. Internal 50a ats will switch to inverter and power all the things on sub panel. NO MANUAL SWITCHING. But please do reasize you are not trying to power whole house power. That requires 100a , or 200a services and a shit ton of power storage. (Batterys) its call back up. In this way your stake stay frozen, your coffee perks. Your favorite tv show plays.
It is a fairly simple straightforward install
