Chris,
I strongly suspect that William is correct. It is a power quality issue
caused by the charger section of the inverter/charger. I encountered a
similar situation with a customer's OutBack VFX inverter several years
ago. He purchased a new electronically controlled propane range and a
couple of UPS units to back-up his computer. Both worked fine with just
the generator or just the inverter, but if the charger started up to
charge his batteries then all would go off-line. No amount of tweaking
the charge rate down would eliminate the drop-out. A low-pass
power-line filter for each appliance might cure the problem. My
customer just learned to live with the issue.

G'day All,
I recently got pulled into someone else's mess on a twin xw-pro 6848 with a
Generac 20kw air cooled genny. A little back story. The client is currently
off grid with basically an all electric house. I know, I know, lol. The
intent is to bring the grid in but that has been slowed for various
reasons. On to the issue. So the electric appliances do well until the
genny is running/charging and then certain items like the electric dryer
don't like to operate at this time. Turn the genny off and it runs fine.
The genny only has 900 hours on it and is serviced by a local genny
company. The client has no internet or InsightHome, only the SCP along
wiith a Schneider AGS module.
Admittedly I'm not overly familiar with the Schneider product line. I've
reviewed every screen on the SCP looking for further genny settings but see
no detailed adjustment that might be able to be made, to "smooth" things
out so that the genny will play nice with the XW Pro and the dryer.
I have reached out to Schneider directly but still no response after 5
days. Looking for any insight (no pun intended) from the Schneider users
out there.
Sincerely,
Christopher-

Chris:
I have little Schneider experience but I will describe a problem with an
Outback system that might be relevant: When the Outback Radian inverters
would charge from the generator, in certain modes (there are a several
generator utilization settings) the charging circuits would inject large
amounts of THD onto the inverter output circuit. This would cause breaker
tripping and other problems.
To track this down we had to rent a pricey power quality analyzer. Here is
a link

to a write-up I did.
Hope this helps.
