8kva inverter sometimes not charging batteries past 94%
Hi, Hope someone could assist. I'm fairly new to this inverter and have a question with regards to the SOC of the batteries. I have 2x Volta Stage 1 5kw battiers and a 8kva Sunsynk inverter, connected to 18x 460w PV's. During a full sunny day, the batteries charges to 100% and then drops to 93% or 94% and stays there, not charging to 100% again. Is there a setting that does this? The SOC line below for reference.

I would be happy with 95% as that would extend the battery life -not forcing voltage on the cells when full. However I think the BMS is controlling the voltage to below the 100% mark. Your battery manual will indicate the voltage that it is full, see what is reflected on the inverter to confirm battery is controlling the stop charge point
