I'm looking at an off-grid quad inverter setup for a client, not my
installation. One of the stacked.inverters is extremely hot, sometimes it
goes into F66 and takes down the adjacent inverters with it to F66 probably
because of these Xanbus network is broken.
I disabled charging and discharging o
Going out the door.
If the bad inverter is the master. You will need to assign a new master.
Since this is 1st generation XW you will need to use SCP and probably
use the manual if you are not familiar. Rebuild the xanbus network.
That is alot of loading and the usual warnings about heat kill
Hi Jason,
Have you checked the black removeable air intake filter on the bottom of the
inverter to make sure it’s not clogged up? Check fan operation with a piece of
paper above the inverter – is it blowing air? That’s where I’d start.

Disco 250A breaker on bad XW and remove its xanbus RJ45. Assume the bad
one is not the master?

Yes, I checked the air flow. It seems equal to the others. It's really
strange because after turning off Inverting and Charging, the unit is idle
and does not cool down. That's worrisome.

It has a Combox and I was able to check the system using the web interface
on the local network. There were no faults at the time I was there, but
there was an OverTemp warning. I have not personally observed it with the
F66 error, so I don't know anything else, but it stands to reason that

Yeah, my next step was going to be that. It is the third inverter in the Xanbus
daisy chain, and not the master, so I assume when it faults due to overtemp and
shuts down, the Xanbus network stops there. Because there is no Xanbus
terminator in the #2 inverter, it can't communicate, and the #4 inve
Yes worrisome. The fault log will show possible causes. The
troubleshooting guide will tell you too look for black chunks of mosfet
transistors in the right bay of XW down low. Really rare, but in a hot
environment 10 years is pretty amazing.
All of the docs are on the Schneider site under XW
