Hi Jeremy, I have a lot of LiFePo4 battery systems out there on the Outback platform and we ran into that issue also. The main issue with the Low SOC alarm is the blinking red light that tends to unsettle clients. The trigger for the Low SOC alert is adjustable though, and it’s pretty easy to change the setting so that the Low SOC trigger is [more] appropriate for the LiFePo4 battery.
Look for" Flexnet Advanced Control" in the “MATE3S” Settings menu. You can change both the Low SOC trigger and the Critically Low SOC trigger values. Note that for some reason you cannot access these particular settings remotely through OpticsRE. I really like having the FNDC data available through Optics RE so that I can check up on things remotely, and I’ve found that the energy tracking seems reasonably accurate given that it was designed for lead acid technologies. Feel free to reach out off list if I can be of more assistance. -Luke Christy Renewable energy consultant.
