September 15, 20232 yr Good day Can someone please assist with the correct pinout for this cable? The instructions from Segen for connecting to BMS attached, but no instructions for the cable itself. Thanks in advance! da4dfbe7c250f22fe4a5a7bd261bedd8fc0af097ba3bb8896be1986c6516319f_optim.pdf
September 16, 20232 yr I just went to look at my cable for you but the wire colour's are sealed over so you can't see... I got my cable in the inverter box
September 16, 20232 yr Author Thanks Sam, managed to get it working. Here is the correct pinout for the RJ45 cable: Inverter 5 to battery 7 Inverter 3 to battery 8 Battery type needs to be set to PYL. Seems the Kodak BL3.6 is manufactured by Pylontech. I got the pinout wrong initially and then got the dreaded error 61, so thought I had to do firmware first. Double checked the cable this morning and noticed my mistake. Once fixed and plugged in battery light on inverter started flashing and charge/float voltages automatically set. Seems to be properly communicating now (does the battery light/icon on inverter keep on flashing or is it supposed to go solid again?).
