Hi All,
I need help with my Axpert King 5Kw that came with 71.90 firmware.
My inverter has the 'PYL' battery option but I am not using Pylontech batteries, so I am forced to go with the "USE" option
I am using 2x wall-mount LiFePO4 batteries that each have their own build-in Daly BMS (48v 100AH)
Everything works great except that the inverter prematurely switches to float charge, so now I have a case where the battery's SoC is at 70% and the inverter tries to charge the remaining 30% with only 4A, bulk normally charges around 20-35A from MPPT.
The batteries, according to the manufacturer supports CAN- communication at 500 kbit/s, I tried the PYL option with a CAN-type-b and CAN-type-A cable but I get a fault 61(communcation error) on the inverter. I think Pylontech uses RS485 for comms?
My goal is to charge my batteries without the premature float, best case scenario is to have comms working between the inverter and battery.
You help is much appreciated
