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

[Jason Lerner]

This system was 9 years old and I was called in to put in a new battery bank.  We added a Combox,  but did not update the firmware on the XW’s since there had only been one update, it did not add any functionality that the customer needed,  and I didn’t want to introduce any new problems (exactly like you and others have mentioned) with a new firmware update.  

The Combox had the most recent Firmware,  is there a possibility it doesn’t play nice with the older firmware of the inverters??

Thanks very much,

Jason
