Battery light flashing?

2 x 5.2 kWh batteries with AC3 inverter.

I am sure the charge indicator lights on the two batteries have always moved in unison...

Right now:

Slave: Status green, two charge lights on steady
Master: Status green, only first charge light on and that is flashing.

Is this a cause for concern?!

Thanks

You have one battery SoC drifted down below 5%. Hence its flashing.
If you've BMS 3005 or 3007 it will charge fine once you have surplus solar.
If it charged to 100% it will reset the SoC internally.

A fix for this is in testing. See other posts relating to SoC drops

Thanks for the reassurance!

I was due to go from BMS 3005 to 3007 and decided to do that as it would force batteries to full SoC.

Slave shot up to all SoC lights on - Master seems "stuck" and first SoC light flashing again!

See this graph: 

(If that works - not tried to link an image before)

hi i have set my battery to charge 0100 through to 1700hrs for some reason its not charging at all ,any thoughts

GribinIsaf Did you perform a Soc Calibration after the firmware update?

Full discharge to 0 followed by a full charge to 100%

Did not ask it to but looks like it did it by itself - see this graph:

All seems fine now

Thanks for your help
