Not for 120/240 split phase.

Whaaat? Can’t you use Multi Unit Config using the SCP Advanced menu to set
additional inverters as Slave?
Thank you,

I just finished a call with Schneider Electric tech support about setting up a
multi-inverter XW Pro system. My complaint was (and is) that despite what the
manual says, you can't set up a XW Pro slave unit in a multi-inverter system
using the system control panel (SCP); that can only be done using the gateway
or the configuration tool. And once a XW Pro is set up to be a slave, the only
path back to being a master is with the gateway or the configuration tool, or
to reset the unit to factory defaults with the SCP. Technician explained that
the 20-year old design of the SCP doesn't have enough memory to allow the
120/240 split phase options. However, it does seem to have enough memory for
120 or 240 single phase and 120/208 three phase, ...
The reason this is a thorn in my side is that Schneider wants to market this
inverter for off grid use and seems to totally ignore what happens when you
have an off grid power system failure. If you have a master inverter failure
and need to reconfigure the system, it needs to be something that can be
corrected easily - in the middle of the night. No ac power, no computer, no
phones, no internet. The only option seems to be to reset a slave unit with the
SCP and then reprogram it.
No longer as enthusiastic about using Schneider for off grid power.
