I would like to request your help for solving faced problem.
I have SMA back-up solar station with the following configuration:
- Sunny Island 8.0H - 3 pcs.
- Multicluster box 6.3 -1 pc. (for extention possibility).
- VRLA battery 800 Ah x 24 pcs.
- Sunny Tripower 15000TL - 2 pcs. - due to solar panel installation maximum solar energy production ~20 kW*h
- External grid is connected to system via request as generator
After half a year of working I have started to get the event 9325 “A 20% recalibration of battery state of charge executed with a leap greater than 10%”. I also read manuals and made requests to manufacturer, but my problem haven’t solved yet.
Have somebody met the same problem? Could you please reccomend me something?
Thank you in advance
