Inverter Settings When Disconnected

For the next 2 days the coach will be disconnected from AC power in the driveway. 640 watts solar and Outback 80 controller and Xantrex 3012 inverter.  Not sure settings to minimize power loss. Although coach will only be "unplugged" for 2 days in this scenario I'm also interested, generally, in how to preserve batteries when unplugged for longer periods.

Here's what I've done. Suggestions welcome.

1.  Left Outback as is. Still don't understand settings but assume it will do what it can with available sun.
2.  Victron 700 battery monitor showed 99.3% and  13.0 v as I left the coach outside
3.  Turned Xantrex inverter "disabled", charger "disabled" and System "standby"
 4.  Salesman switch "off"

Anything else tonight?

Anything else in the morning? Should be sunny day.

In this case we'll need to be able to crank and leave Wednesday morning 6am, but what about longer periods as well.

Thanks

Randy,
If I were going to leave unplugged for a couple of weeks I would disconnect the Chassis batteries.  The parasitic drain is such that the batteries would probably be dead or close in a couple of weeks.
Just a suggestion.

Randy has a battery combiner, so any time he has a solar charge, house and coach batteries are charged at the same time. With inverter off and salesman switch off, solar should be able to handle the small parasitic loads of detectors and alarms and ecm's with no problem.
