When staying for an extended period of time, is the setting I should have the inverter/charger set to is "stand-by"

If you're talking about the Inverter/Charger to run the Residential Fridge, I leave ours on (been on for a year now), it cycles to the proper mode and then I don't have to remember to turn it on when we start moving again.

This is the same as I do... I turned it off the first time , and forgot to turn it back on...
