I have not found where this adjustment is made in OpticsRE. Can someone point me in the right direction.The FNDC low SOC fault is merely a default informational warning. You can set the SOC warning level to something lower if you want so you don't get a low SOC error every time you hit the connect SOC.

Batt SOC Low Warning FNDC-10 Fault
I'm receiving the message in the subject line on the Mate3S display. This started after experimenting with some new (lower) values in "Grid Connect SOC" while using HBX mode. I read in a different post:

Re: Batt SOC Low Warning FNDC-10 Fault
Thank you. I made the change I needed manually. So it's not accessible from OpticsRE?
