Recall 22V-144 Solar charger wiring

[hondapro87]

I got the letter about this recall and mine is wired wrong. My question is does this only affect the 12 volt system when it is not connected to shore power and the battery is getting charged by the solar panel? Or is the high voltage still present when hooked to shore power? I don't want to be sending 42 volts to the control board of my water heater and refrigerator. Thanks
