May 16, 20224 yr Hi... I am having an challenge to connect the CAN Bus on an BYD B-Bos Pro 13.8 battery to an Sunsynk 5Kw Inverter...? I can see on the BYD Box it is Pin 4 =CAN H and Pin 5 = CAN L, the pin for the Sunsynk Inverter is the same, so if I just cross Wires on Pin 4 and 5 all should be good to go. Did anyone do this connection already and can share some info please...? The installation is outside of town so I need to drive back to try and make it work... Thanks...
May 17, 20224 yr Author I tried the following, but to no avail... BYD BOX: Pin 4 = Can H Pin 5 = Can L Pin 6 = Gnd Sunsynk: Pin 4 = Can h Pin 5 = Can L Pin = Gnd I connected accordingly, but no battery info displayed on the Sunsynk...? The BYD Box Battery only run for an few minutes without CAN Communication, then it disconnects the battery...? How can I make these 2 communicate or at least let the battery remains on and run the Sunsynk on voltage base settings for the battery charge...?
