Double Transfer Switch?

[Wombat Ranger]

Is there such thing as a manual transfer switch, which will simultaneously transfer 2 circuits?

Today I wired in my old MS4448 as a backup for my system while my main inverter is down. My winter project this year is getting my power system all done correctly in the (detached) garage. I have a long ways to go yet, but the old system finally came out of the house last week, and that was a good feeling. I would like to permanently include this "backup" inverter in my system. Seems like a manual transfer switch that would switch both the AC-Out (Main Panel) and AC-In (Genset) would be convenient.

Does it exist?

I would just wire AC-In to both inverters, no real reason to have a transfer switch. If you want to be a bit better you could use a simple breaker panel to turn whichever inverter on that you want on, There is not really a reason for a interlock/transfer switch for this usage.

The point of a transfer switch is to not connect both devices (that could be out of sync) at the same time , for the AC-In from the genset the only real risk is both inverters attempting to heavily use the genset at the same time and worst case that blows the breaker at the generator. And technically if you controlled the power being pulled from the generator for both inverters then both inverters could be connected at the same time.

Makes sense, thanks for the reply!
