[RE-wrenches] Outback Charge controllers resetting to default settings

[Zeke Yewdall]

Has anyone else had issues with outback charge controllers resetting to
default settings?  I just had a FM100 do this (and shut the whole system
down because the default settings were too high of voltage for a 15 cell
LFP, so the battery turned itself off for protection).  The logs show that
the values were set to 0 from the proper settings, then to the default
settings from 0, on site.  But no one was on site.  I changed them back
remotely via opticsRE, and it logged me as changing them back, as it should
have.

Occasionally in the past I've had similar things happen, and always kind of
chalked it up to the customer perhaps messing with the system, but this
time I know that no one was there to adjust it locally at the time that it
says it was changed.

I have another site this week that does not have opticsRE, that the FM100
may have reset to default settings as well.  Same thing -- lithium
batteries shutting off from overvoltage all of a sudden.  I am still
investigating that one.
