Ok my Juntek has been working wonderfully until today, but now fails to do its main job tracking SoC?
Went down to 61%SoC this morning as it didn’t quite reach 100% in the rain the day before, and since it was rainy/overcast and I had an hour drive to Blenheim anyway I linked the alternator/cranking bats after starting the bus and happily saw 48A going in once I pulled off and the revs picked up... problem started when SOC his 65% and didn’t move, even half an hour later. The amps were still tracking 35-45A going in at 27.2V so I just left it and got on with driving that rubbish road... After roughly 45-50 mins the SoC was still 65% and the amps had dropped to 10A going in, so I disconnected the alternator link and left the solar to top it off as the sun made a brief mid afternoon appearance.
When the solar stopped charging at its set 26.6V the meter STILL said 65%, so I power cycled the monitor screen, and when it came back as 65%, I reset it to 100% and though it would pick up and balance out again. Unfortunately by 9pm it was still saying 100% (26.4v now) and I knew it was more like 90% so reset it to this again. Volts and amp use still show correctly, but 2 hours later it’s still showing 90% SoC, so something is definitely gone kooky.
Is there a way to reset the main sensor completely?
Has anyone else come across this issue?
