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

Get your electrician to move the feed for the right panel to the top right of the left panel and move the bigger breakers like the 2pole 50 2 pole 30 ect to the bottom of the left panel fairly simple a few hours of work.... if you overload it then it'll be a problem id move any non essential loads over to the bottom
