Year later and still the same issue. Can't find an answer anywhere. Has anyone found a true solution to fix this issue? Or is the battery going back to Hubble?

Noticed tonight that my screen isn't auto dimming. Not sure how long this has been going on. Still looked at something a couple of days ago and it was dimmed. Setting is enabled. Tried to disable & save and then re-enabled and save. No difference. Restarted the inverter as well.

Any further developments here?

That is a mistake i regret a lot. Might just get this one fixed and sell the pair. Replace with something reputable. When I installed everyone was shouting "HUBBLE HUBBLE HUBBLE" Should have listened to installer and gone with Pylons.

Strong suspicion that they didn't do a thorough test on it.

Since July has anyone found a solution to this? One battery still drops from 40% to zero. Both voltage and lithium settings used to see if that bug is still there. Battery was returned to Hubble before and they just said it passed their load test and returned it. Take it back again?

Exact same problem. One battery will drop from 40% to 0% consistently. Unit was taken to Hubble and they did a load test and firmware update. No change. This after a lot of back and forth… Not impressed.

My whole journey with this is documented earlier in this thread. Sunsynk 5k Shutdown is set at 10% They are balancing yes.

Current state of things.

Not too impressed right now. Battery 2 that was dropping to 0% from +- 35% was taken in to Hubble for assessment. Load test showed an equalisation issues and the firmware was updated to 2.07 and the battery was returned to me showing that it passed all the tests. Hooked it up and did some testing last night. At 35% the battery shut down. Not even the on LED was on. Battery 1 continued flawlessly down to 15% SOC until my PV took over this morning. Set the inverter to AGM this morning and disconnected the CAN cable. Will charge both up and let it balance again and test again tonight. Battery 2 is still on 2.05 firmware. Endless begging Hubble to supply me with the latest firmware to update... Does anyone perhaps have the file for me?

Still have the drop from 38% to 0% on the one battery.... Time to log a ticket I guess.

Thank you. I figured as much. Glad to know my batteries are 100% healthy at 286 cycles. Will hopefully not drop from 38% to 0% instantly anymore. My fiance was not happy with the beeping at 2:00 this morning.

Upgrade completed to P1247V110-12290V205T-0316.bin Inverter set back to lithium and updated the charge capacity to 210ah to cater for the 105ah capacity on the batteries. Solar Assistant now reports capacity correctly as 105 per pack. However, Charge Capacity reports as 90ah? huh Interesting observation. Sunsynk logger shows SOC as 100%. Solar Assistant and RIOT shows 85% @ 53.4v and no charging is happening as the Sunsynk reads the batteries as full. Anyone else pick that up? I assume a full cycle will restore this?

Woke up to a beeping Sunsynk this morning. Batteries reporting 0% SOC. Suddenly dropped from 40% to 0% in minutes at around 06:00 this morning. No difference in usage patterns compared to the night before. SA reports both at 100% SOC now but also 45ah capacity left. Time to upgrade the Firmware. Will request the push via RIOT or do a manual flash with the SA cable.

Bottom right corner on the app tap on "me" and enable notification. Right now mine is telling me every 30 minutes that I disconnected from the grid while the grid is perfectly fine. Might be a little sensitive to frequency and voltage fluctuations on Eskom at the moment. LOTS of variations recorded for the past 12 hours.
