My server rack manufacturer told me that their batteries do not measure power (SOC) if it is below .5A. What this means, is if you have large battery bank and extended periods of low energy usage, the SOC will never update off 100%. Is this a common thing with all BMSs? What good is closed loop comms if the SOC is so unreliable? I actually think my batteries are not registering below 2A.
I started seeing my batteries go flat even though the BMSs were reporting very high SOC.
