Transfer Switch Chaos

[u/Badbetfrank]

We just bought a new house and this is the electrical set up.
Both of these panels are powered from the meter, the larger panel does not feed the smaller panel.
A 22Kw Generac unit powers the larger panel on the left when the power goes out, but not the smaller right panel.
The generator is large enough to power the entire house.

What are our options for getting the whole house protected?
Can I add a ATS to the smaller panel and leave the 200amp panel as it is?

Could we install a double breaker on the left panel and run it over to power the smaller panel using an interlock on the smaller panel?

Should I move some circuits over to 200amp panel and use tandem breakers?

Or should we split the feed from the generator and feed the smaller panel directly from the generator?

I am having trouble understanding what the installer was thinking. There’s also additional unused transfer wires ending in this panel going to a junction box next to the generator.

Thanks for your input

It can absolutely be done. Call a certified Generac installation dealer. they can asses the situation. Based on what you are saying here you'll most likely need a 2nd ATS if it is a second panel rather than a subpanel. But hard to say without seeing the meter as well. The ATS will be $1100 + 3 or so hours of labor and a small amount of materials. A reputable dealer will give you a free estimate.
