JK BMS reading negative amps with no load and PV's on

[tjstepanian]

So I have a LV6548, using a JK BMS B2A20S20P with LIFepo4 16s config battery. After going through botched updates last week on my BMS (IOS phone), I now noticed under NO load with the PV's on (3S2P 250 watt) panels...when viewing my bms app, I see -16 amps while voltage climbs to full SOC. My Ah reading begins to drop as well

If I shut off breakers to PV's... Amps go to +1.2 Amps. Or at night when there is no sun the BMS will read positive Amps as well

Not sure if this is another botched reading from the BMS or do I have an issue with my PV connections ? I made sure I have correct polarities from the panels to the SCC. I believe SCC is configured correctly.

Anybody experience this ??

Need to calibrate the current to zero in the BMS settings

Need to calibrate the current to zero in the BMS settings

Thanks ! The issue has been solved. I ended up re-installing after the latest update, things back to normal.

Hello, I believe I am having the same issue. Is there a particular page in the manual with the instructions to calibrate the current to zero in the BMS settings?
