Help with checking AS after power surge at the house

[Steamguy]

Well, never say 'never', right?

We built this house 30 years ago, and we live so very far out that we 'never' get power surges. The last one I can recall was about twenty or so years ago when a kid hit the pole at the end of our little dirt road. (That took real talent to do.)

Brownouts, sure. Power outages, often enough. But usually, surges are dissipated by the length of the power lines out here and any that do get through are pretty minor.

But the one we got a couple days ago was a real doozie. It felt and sounded like a truck hit the house. It fried our new HVAC but at least left the water pump alone. (That would be a chore, to pull it from 300 feet down...)

I would be remiss if I didn't register my disappointment with the team that designed this new intelligent HVAC; that they didn't take internal measures to protect it from surges - there's only twin 40 A breakers between it and the mains, after all. I have done my share of electronics technical work along with systems analyst work in the past, and I'd sure like to get a look at their schematics...

I have Tripp-Lite suppressors on everything here, and everything else rode through it just fine. Whole-house suppressors weren't available when we built, but I have calls in for estimates now! (Yup, closing the barn door after the horse...)

The AS has been left set to "Use" since we parked it a year and a half ago. I leave it that way because I keep a standalone heater up there. I keep the AS plugged in to 15A shore power all the time, as I have all our other trailers. We tend to keep everything 'ready to go' at short notice as my wife's health is up and down. But unfortunately she hasn't been up for camping for a while.

Okay, now you have the background, and now my question:

How can I check the converter to make sure it didn't get hit? The wrinkle is that we have solar on the AS (Zamp controller) so I'm looking for advice here.

And is there anything else I should be checking?

My own mobility is rather less than perfect, so there will be some delays in doing the physical stuff.

Thanks in advance.
