But the two inverters are logically separate.  I.e. it might
be a single board but the "common failure" would be something
on the upstream side -- power supply, decoupling, etc.

I like seeing what has failed so I know what else to look for.
E.g., has the power supply gone out of regulation and fried
the inverter board (if so, it's going to fry the replacement!).
