<p>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.</p>

Spoke w/ a former member of their (OB)'s tech support and was told that the counting of amp hours both up & down drifts so you have to recalibrate monthly.
<div>This IS something OB is aware of and has no interest in addressing. Thoughts.... remove and when you find a device that I am able to install and get accurate info on multiple shunts to trigger gen start let me know.T <br />

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.</span></div>
