Re: Inverter Question
I've got this same stupid feature on a Mastervolt combined charger/inverter. You have to actively shut the inverter off at the panel after removing shore power or it just runs. Who was the engineer who thought this up! Guess someone thought you'd want 110 on the outlets no matter what, automatically. Not a sailor with a limited battery bank.
I've had a yard ruin batteries by running the inverter for weeks without detecting it was on.
The Mastervolt has a switch on the inverter that has 3 positions. On which provides this "wonderful" feature, off, and charge only. I leave it in charge only unless I'm cruising. Plugged in on the dock, if shore power fails, this wonderful system will run down your batteries if you run it in the on position.
