Hi All,

Went on holiday in December and my pylontech started discharging fully and cutting all power, not reverting back to utility. Since I got back this has happened more and more often, now nearly every evening. I have set ICC to Utility before I go to bed and the battery is at more than 50% SOC, this should mean that hardly any battery drain through the night. However issue remains and loadshedding hits my house only (self inflicted this time)

I have chatted with Johan and seems that there is a firmware update required on the pylontech, however when i reach out to installers(as Segen doesn't deal with end users) they say that Segen takes forever to possibly upgrade the firmware, they wont let installers or end users do this. Anyone attempted it?

Has anyone else had similar experienced and what works around have you implemented?

I have resorted to now assign the battery management in ICC to the mercy of the inverter to manage SOC  by disabling pylontech and SOC in the settings  

The notion of adding another batter at R20'000 to fix a firmware/comms/software issue is not a viable option, its like using a cannon to kill a mouse

I think your cheapest option will be to add a BMV 702 for around R 2700. This will give you an accurate SOC and ICC reads the BMV SOC.

In the meantime I would recommend that you ignore the inverters SOC and only use the voltage for control. The Axperts voltage reporting is better than the SOC.

Thanks @GVC much appreciated

Do you midn sharing the steps on how I should make these changes on the inverter, its an Axpert5KVA

Disable SOC control in ICC, then on your inverter change:

"Back to Grid" = 48.0 (setting 12)

"Back to Battery' = 52.5" (Setting 13)

Setting 12 and 13 only work if setting 1 = SBU or SOL.

You can also use "change by time" in ICC instead of SOC.

Thank you very much, really appreciated!
