[C320-list] power outage with fridge on question

[Chris Block ..._/) ....._/)]

I was wondering if anyone had a "work around" for the following scenario:

You're plugged in and running your fridge and the power goes out at the Marina.  How does one prevent running down the batteries past their safe 50% level?

Is there a type of sensor/switch that says, if I'm not connected to 110 at the charger, turn off the batteries?
