June 4, 20242 yr comment_16570 Hello, I have planned a 60, 70 KW PV system with one SUNGROW inverter SHT20 and one SG12T and two SUNGROW SBR storage unit (25.6 kWh). In order to increase the level of self-sufficiency from around 31 percent to 70, 80 percent, I tried to increase the number of battery systems per group/storage (two groups each with an SBR 25.6 kWh storage). Unfortunately, the level of self-sufficiency does not change, even if I add 6 SBR 25.6 kWh storage units to each of the two groups. Why is that? (Watch pls my attachment) Thank you so much, Martin Report
