Hello everyone,
I have a question regarding the battery clusters connection parallel. There are six clusters each consists of 14 lithium batteries of 100 Ah in a 250 kW PV system. The problem is cluster 1 and 2 will charge with low current and discharge with a bit higher current around 1 to 2 Amps, which makes an impact on the SoC of the clusters. Among 6 clusters, cluster 5 charges with higher current than all others. Although all are in parallel but the problem persists. What could be the possible reason.
P.S: Cluster 1 and 2 were disconnected for sometimes due to a fault. But all are now operating together for more than a month now. The system was installed almost 8 months ago.
Looking forward to the experts opinion. Thank you
