Hey folks! I've got a 3-year-old Conext XW Pro setup with an MPPT 60, SCP, and a Discover LiFePO4 smart battery. I'm trying to configure my system to shut down when the battery discharges too low. Unfortunately, the Low Battery Cut Off (LBCO) feature doesn't work, and Schneider isn't providing a fix for it. I've also found that the RPO option is ineffective as well, which Schneider has also failed to address.
Now, I'm looking into the State of Charge (SOC) option but I'm struggling to find detailed setup or configuration instructions, particularly pertaining to the Insight Home screens. I do have the Schneider battery monitor, but I'm unsure if I need it since the smart battery has its own Battery Management System (BMS) integrated through Xanbus. Moreover, Schneider hasn't been able to clarify whether I can operate both systems simultaneously on the network. If anyone has links to setup guides or can share insights into these concerns, that would be super helpful. Thanks a ton!

It sounds like you're in a tricky spot with your setup! First off, what mode is your system currently running? (Like load shave or grid support?) Also, have you checked your LBCO settings in the advanced menu? Sometimes, the voltage, hysteresis, and delay settings can cause issues. And is there a data cable connecting your battery BMS to the inverter? That might help too!
I feel your pain. The features you mentioned not working with the Discover battery is a known issue. It's frustrating because they really should have tested this better before releasing it. The SOC is definitely the way to go, but I'd advise keeping a close eye on how your system functions with two BMS on the same network – there might be conflicts. Have you managed to find any resources or guides on setting that up?
Honestly, I wouldn't stress about LBCO since, with the Discover battery, it's not user-configurable. Since you’re off-grid, focusing on SOC sounds like the right move! I really think getting that setup right will serve you better.
