Multiple Problem with SUNGROW SBR 25,6 kWh storage and the self-sufficient value


Recommended Posts


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?

Thank you so much,

Okay, I know the solution. There is currently no combiner box from Sungrow, which is why you cannot connect several SBR/SBH batteries together. In general, you can only connect one battery to an SH25T. (SUPPORT answer June 4, 2024)
