Hi Bill,
I looked at the Magnum manuals and the way i understand the fault you are seeing is if the incoming AC power (either the genny or shore) exceeds 150v then the inverter charger will show a fault of High Volts AC. if the fault is a hard fault, it will shut the inverter down.
your inverter and or your auto transfer switch (if it is like mine) monitors the incoming AC power and if there is a problem with it in terms of voltage, frequency that is out of range, it will shut power off to the coach. your inverter if it detects a problem and the transfer switch (with power monitoring) doesnt, only the inverter will shut down ( ithink). if there is a hard fault, the inverter will reset itself. the manual says to leave all AC power off for 15 min and then try it. i suspect it will autoreset much quicker than that and it probably did.
it is very likely NOT due to heat. 105 may be hot to you but really isnt that hot for these things. i ran my genny in my driveway at 115 degrees all day no problem. we ran for constantly while we were on our trip while driving and alot while sitting and it was 105-115 during that.
if your inverter is overheating you will get a different overheat fault, not the high voltage AC fault.
assuming you were running on genny only, i would assume one of the following if everything is working ok now.
1. a glitch of somekind from the genny
2. a false error
if it was me, i would just reset the fault, and run it and see what happens. again i believe you have enough safety systems monitoring the power that if the power is bad that it will just shut you off.
my prosine xantrex got into a fault mode and i had to disconnect power from it and rehook it up and it reset itself.
and no problems after that. (and that was before my last trip)
call me monday if you want me to talk you through it
