Do you know how to change the charge voltage when in lithium mode? The battery charge settings are not available on the DEYE inverter in that mode and I don’t see that option when using the BMS software.Well, my wires (and I guess my understanding) were backwards. I snipped the ground wire, and that didn't do anything. I finally just reversed my 4&5 wires, and it worked! At this point, I'm not trying to understand it...
For anyone else who may come across this, here was my final wiring diagram. I have T-568A on the Seplos side (though could be T-568B - won't matter for these two wires) and the below picture on the DEYE side (blue on pin 4 and blue/white on pin 5):
