We have learned that in addition to power surges that low voltage can damage both the AC and refrigerator.

Its always smart to check the voltage upon arrival before unhooking or plugging in. You can do that with a cheap multi meter. I use one off Amazon that is AC/DC with a Hertz mode. While your there you could just have a voltage meter plugged into a wall outlet, that way you have an idea if your getting enough volts.
Progressive Industries EMS hard wired in is best if you want good protection from high or low voltage, bad grounds and surges.
My minimum is something like this for checking out AC outlets and DC batteries:

I used to think the same thing about Progressive. So much so that I bought a hard wire 30a. I didn’t know I had a problem from a surge until I smelled wires burning on the ac out side of the unit. To make matters worse, when I called Progressive they not only were of no help but cut communication on the first call. The tech checked to see if they would warrant the unit, his idea not mine since I never mentioned warranty, and when he discovered there was no warranty available he cut the chat off and would not return additional emails. When I called there was no additional help available. I was hugely
disappointed from a company that had such good reviews.
Just my experience.
