For now I would just use one XW to charge. They are 130A chargers so set one to the percentage of charge to get the correct amps. Use the master. Disable the other 3 chargers by deselecting operating. Everything on an XW is DSP controlled and can be set. Maybe the "schneider lady" here can help. I did correct a problem like this and I had to use the "config tool" to do this. I also needed help from engineering and it was a long time ago.
Good Luck!

I have each inverter set to 22A charge rate and 57.6 for bulk and absorb, no equalization (although the eq voltage is also set to 57.6V just in case). No solar at this time (yet!). I do have one other piece of information I just discovered. Two of the four inverters are reporting the battery voltage about 0.8V lower than the other two. I think this might be my issue. At rest two of the inverters show the battery voltage as 53.4V, which is the correct voltage as measured on my meter and on the battery BMS display. The other two inverters show 52.8V and 52.7V in the Combox diagnostics. I'm now thinking these two inverter battery voltage readings are the issue. Is there a way to calibrate the XW battery voltage readings? I suppose I could disable the chargers on these inverters, but that is not a permanent solution if that is found to be the issue.

They are hitting 58.4V and tripping the battery management units on a set of Lithium Batts. Any ideas why this would happen? I can disable chargers on individual units, so I know the settings are getting uploaded via the Combox.
