yousuf2217 Posted March 6 Share Posted March 6 I have 2 x 8.8kw BSL batteries installed at my place, thats running through a Sunsynk inverter. I've had the system installed in Feb23 with no issues since. However, this past Sunday, one of the batteries have just been stuck on 80% SOC. Its not charging or discharging. (the other battery is working perfectly fine) I've tried the recommended 'shutdown and startup' process that was recommended in another forum, but there's no change. Has anyone experienced anything similar, or can suggest how I can go about troubleshooting this issue? Quote Link to comment Share on other sites More sharing options...
madness_za Posted March 6 Share Posted March 6 Try running one battery at a time? zsde 1 Quote Link to comment Share on other sites More sharing options...
yousuf2217 Posted March 6 Author Share Posted March 6 Not sure why I haven't thought of doing this yet - thanks, will give it a go tonight. Do I need to change any cables/dipswitches before I try to just run the one battery? Quote Link to comment Share on other sites More sharing options...
zsde Posted March 6 Share Posted March 6 (edited) Do those batteries have LED indicator lights for the charge level? If so, is that indication also stuck? 1 hour ago, yousuf2217 said: Do I need to change any cables/dipswitches before I try to just run the one battery? Yes, your slave battery once targeted as primary stand alone will need to be changed to be the primary via the dip switch.
