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. Zeke -- Zeke Yewdall PV Engineer NABCEP #031508-89 [email protected] 303-523-3592
