The system will auto reset when IT thinks there is enough voltage. I finally realized that WRV put 8 GC2 batteries with 960 amp/hr in there for a reason. Previous coaches I have had did not need anywhere near that much power and only had 4 or 6 12v deep cycle batteries.
I went up to the 2300 UTL Interstates for even more AH. My Aquahot thermostat is happier too.
