I have a 4 x 2.6 kWh system with an AC3.0
When the system reaches 7% charge it stops providing power until 12:30am as I expect. However the LEDs on the 4 batteries do not appear to be consistent.
1 battery with 1 LED flashing
1 battery with 1 LED
2 batteries with 2 LED
To my untrained eye this looks like not all the batteries are anywhere near 7%
Am I expecting too much ? Or does something need sorting ?
I had this on BMS firmware 3002. Upgraded to 3005 they now are better balanced, but still not perfectly equal, especially if I have a few days of less than 100% charge. They begin to drift, but at least now they still charge back up and re-equalize themselves next time we get to 100%
I already have BMS 3005 and I charge to 100% every night. Since install install at start of May things have been the same.
I think this will be a raise with GE support and they might run a calibration. But I would expect all batteries to flash 1 LED personally.
Thanks - I will talk to GE
