Forgive me, I wasn't clear. In my example there were multiple code violations. The big one is backfeeding a panel without a lockout system to keep a systematic way to keep current for zapping line workers. A variety of switches would allow a truck or generator to not kill line workers.
No problem. I mentioned a transfer switch though. That negates the backfeeding issue, right? Others? I'm not trying to be at all confrontational. I just need an education.
But I also intended to convey the idea in the post title that our house has very limited electrical needs for just an old, relatively inactive couple, not a big, young family, in domicile. One thing about wanting to back up our house, a lot of our use is scattered throughout the house, e.g., a security company alarm system powered by an upstairs outlet, security cameras powered by outlets, or doorbell wiring on our front and back porches, our living room, etc., all areas that we'd have no other reason to back up but well within the capacity of the truck to handle since there's nothing else but these low-powered devices on these circuits that Sunrun would probably want us to leave out of their BUP sub-sub-panel scheme.
I did give Qmerit a call. At the time, I didn't have the $3,350 additional quote for "home improvement." They said they couldn't match the $8,900 price for the basic home FCSP and HIS installation. The person I spoke to said that most other quotes that he'd heard of ran at least $14K to $15K with all modifications necessary, and the part that beat me(!) was that the guy said that Qmerit was a Ford partner, too (with the Mach-E), and they didn't want to be encroaching on another Ford partner's territory!
. I checked with our electric utility, and they confirmed that both the proximity to the gas meter and the rust in the main panel (a safety issue, they said) needed to be addressed.
I completely missed the transfer switch part of the question. Yes, that's the point of the switch. There are different ways to skin the cat but a manual transfer switch like the Generac 6752 - which apparently handles the bonded neutral of the Pro Power Onboard system - is probably the best way to do it.
That would be great if it were true. But, for instance, here's a Delta circuit schematic for the whole shebang with photovoltaic input. The "critical load panel" is essentially the backup panel (BUP) or restricted loads panel. I don't see any provision for returning unused residual power to the main panel or any subpanel connected to it (but then I'm not very good at reading wiring diagrams or schematics). I imagine any other subpanels in a house are in parallel to the MID device and come off the main panel. They would not be backed up.

A little Nextdoor story. A woman posted pictures on Nextdoor of linemen standing around 'doing nothing with their fingers up their a$$es' during a recent power outage. "WHILE HER POWER WAS OUT!" It didn't take long to find out that they were waiting for the circuit to be isolated from a backfeed.
Slightly off topic but what exactly happened when you backfeed the grid with a generator? Won't it immediately trip the breaker when it attempts to power all of your neighbors houses?
Yep seems odd.
