I ran across two features when looking over the advanced settings on my SCP. These don't appear to be documented in the materials provided by Xantrex -- at least that I can find. Any clue what they are or what they do? (RPO and Power Save)

Advanced Settings
- Advanced Features
- RPO
- Power Save

I think you will have to call xantrex support on this one .. I have no clue what they do

After some more digging I found the options online in the 230v version manual. (Europe 230v Model / XW6048-230-50) It seems like the RPO function might work on both models, but the Power Save may be limited to the 230v model. My manual only goes to p. 3-28 for the 120/240v model, but this is on p. 3-30 of the 230v one.

Item Description

RPO Remote Power Off.
RPO enables or disables the remote power off function.
Enable this setting if an external shut-off switch has been connected to the
XW Inverter/Charger Aux port. See the Installation Guide for more
information about the Aux port.

Power Save
When enabled, Power Save mode can reduce tare loss from the battery by
reducing output from 230 volts to 210 volts when the loads are less than 100
watts. When the XW Inverter/Charger detects loads higher than 100 watts,
the inverter/charger produces the full 230 volts. Power Save mode is
disabled by default.
