Jason, This isn’t an AC coupled system is it? There is a very common issue that can occur when you AC couple XWs on lithium batteries.
If this is AC coupled, I’ll go into more detail on what I think your problem might be. Also, let us know if you got it fixed.

The voltage rises too quickly and the battery management systems disconnect the battery. What is the calibration process? I still plan to disable the chargers that are reporting the wrong (lower) voltage and see if the others (individually) still ignore the setpoints. It's a very remote location, so diagnostics are extremely difficult.

However, based on your discovery of different DC voltages from the inverter, my recommendation is to calibrate them.

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.
