[RE-wrenches] Xantrex XW 6048A unregulated during charging

[Tump]

As with anything these days I would make damn sure that the firmware OF ALL components in the system have been updated w/ the latest firmware prior to changing anything. I personally am not a big fan of the com box and I have the “Con fig” tool and I find after the learning curve its the best method of addressing info & updating. Mis matched firmware seems to be the # 1 issue w/ all the manufactures today. Tump

When charging from AC 2 - generator, the battery Voltage rises above 62 VDC,  but not every single time.  All the settings are correct, EQ is turned off, and if it accidentally got turned on is set at the same Voltage as the absorption setting.  Customer has a brand new 33 kWh AGM battery bank,  that I would rather not fry.  This is a battery backup system with no PV.
