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...

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...?
