Just another reason that Soc needs to originate from the BMS in an OEM battery system. It needs to get into the Schneider and Outback web portals for monitoring. Is there anyone building an Offgrid battery besides Discover AES that does this? I don't think so.

I have several systems with LFP batteries that have both a eGauge (communicating directly with the battery BMU) and a FNDC and I get wildly different SOCs. In a typical 24 hour period (12am-12am) I get SOCs on the FNDC that vary 2% to 34% of what the battery BMUs are reporting. I am assuming that the BMUs are reporting accurately. I would think a 1%-5% difference would be acceptable. Any help or thoughts on this subject would be greatly appreciated.
