I own a 2008 40-C Mandalay, 50-amp system, ME 2012 Magnum charger/inverter.
About a month ago I changed out the four house and start batteries. I keep the coach plugged in to a 30-amp system at home when not traveling in order to run fridge and one AC due to hot humid weather in south Louisiana.
I noticed today with the fridge running and the one AC running, the VAC had dropped to 105 to 108 on several outlets.I was pulling 22 amps with battery indicating 12.3, charger on and inverter off.
My question is, what is the proper setup for the charger/inverter when connected to shore power? I have been told not turn the inverter on when connected to shore power. The 105/108 vac concerns me.
