  1. I have taken your suggestion regarding the bulk charge time and set that to 900 minutes, I have dropped the the bulk charge voltage to be the same as the flaot charge (54v). So now atleast the battery will get a constant current and voltage. Inside the battery there is a BMS which manages 15x 3.2V cells, the reason I decided to go with the bulk time hack is because the BMS inside the battery will actually stop charging the cell once ideal volts and current is reached. Thanks for your detailed reply @Coulomb.
  2. 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 https://ibb.co/WF6sNCM https://ibb.co/2vt0Npy https://ibb.co/1Xn7dT9 https://ibb.co/tQTccM5 [url=https://ibb.co/WF6sNCM][img]https://i.ibb.co/sQ2tp7N/20210220-120437.jpg[/img][/url] [url=https://ibb.co/2vt0Npy][img]https://i.ibb.co/D9CPpjt/20210220-115457.jpg[/img][/url] [url=https://ibb.co/1Xn7dT9][img]https://i.ibb.co/2M6Wsdj/20210220-115534.jpg[/img][/url] [url=https://ibb.co/tQTccM5][img]https://i.ibb.co/rFRMMGJ/20210220-115510.jpg[/img][/url]
