If I turn the battery disconnect to on, the voltage drops to a normal level and everything works normally.
There's another sign.
Who's this "someone" who forgets to connect the batteries?
Its used by a few people. Mostly my wife and I together. She will also take it solo at times. My daughter and her BF. My Son. Enough minds involved that there is a high probability one of us will forget and fry the electronics at some point.
If a new converter regulates the house 12V regardless if the battery is connected or not, I’ll get one, problem solved. If not I may eliminate the converter all together and have the 12v isolated and maintained by a separate A/C charger and solar charge controller. I’ll just be careful until the update later this season.

Your system is wired all wrong for circuit isolation. If when plugged in your converter delivers more than 13.5 volts for floating the batteries, it is a battery killer. Old converters are hammer and chisel guesswork on the part of the manufacturer. I would be worrying about solar compatibility, down the road.
I am going solar late summer or fall. The current converter isn’t part of the plan anyway.
Is 16.5V more than 13.5V? JK!
I had thought 14V-15V was what chargers typically charge at the high end, working their way down. When I saw 16.5V, I thought regulator issues, not battery charging. Now knowing the battery IS the regulator in the cheaper converters, yea, it was a regulator problem LOL I didn’t know 12V chargers went as high as 16.5V for SLA or GEL batteries.
