Well Damn! Got a battery under voltage alarm (
@Lighthouse Beacon eek!) and an Alarm on battery #2 ... the inverter switched to bypass...
I checked voltage on battery 2 screen 48.4 and param #14 was set to 49.6 so it should have been alarming ages ago... wtf....
Default in the manual for Param 14 is 44 but for some reason mine was set to 49.6...
This is why I asked Sungold for defaults etc but they only gave me the secret 'reset to factory' key.
I reset battery and it cleared on the Battery but not on the inverter.... I then unplugged the BMS Comm Cable....and error cleared, plugged back in and error still clear... but still in Bypass mode...
Turned AC input off and it went back to battery
I then changed param 14 to 44 ... but WTF...I don't know what I'm going with all these charging/under/over/etc params...
(oh also overcast/snowy/batteries SOC dropping - currently at 36% average/aggregate)
I'm tempted to just 'Reset to Factory' and then adjust the battery params as instructed by Sungold for their batteries......but I wanted to get through the month and see the result on my Xcel Electric bill first.
I tried resetting etc. For now I have the battery turned off and disabled.
On the battery display one of the 16 cells is reading 2717 mv all others in the 30XX range.... also the battery display shows a UV error which is what the inverter is complaining about.
Does this battery just need charging/cycling or is it potentially broken?
