February 12, 20233 yr Hello colleagues, I have a PV system with an Azzurro inverter and a battery tower from Pylontech Controller: sc0500 and 4 batteries H48050 These were put into service in October 2022. Now I bought an additional module to have a storage of 12KW. Since a week is not charged further than 89%. the self use mode also no longer works so really. Now I would like to know what the reason can be. I can not change anything on the inverter. Since I can only adjust: Battery type -> Pylontech Max charge: 35A MAx discharge: 35A Batteryadress: 00 Unfortunately I can't find anything here.' Is there any way to look at the battery states? Thanks already.
December 23, 20241 yr Hi pitje74, It's my first day here and I've no experience here. Your Post is several days Oldenburg but your setup is similiar with mine. We use an Azzurro Hyd 15k first with 4x H48050 and I added 3 additional Powercubes on 19th of December yet. After Restaurants the highest charging Level was about 85 %. Reason was the different SOC of old stack (lower) and new blocks (higher). The lowest SOC of one Module delimits max SOC because charging is stopped when the first block reaches 100%. Over RS232 consulting I detected the lower ones when the others reached 100%. Then I disposed the fully charged remaining the 85% blocks. Then I charged them to 100% and readded the previous removed blocks. The result was a SOC of 98 % and after a discharging/charging cycle of 99 %. Now I hope for 100 % because of automated balancing in the near future. Your issue already solved? Feel free to ask for Mode details if needed.
