The inverter manual says 2-Ground, 4- CAN H and 5 - CAN L and the BMS says 4 - CAN H, 5 - CAN L and 3/6 Ground. Does that sound right?battery end , normal utp connection

be careful in the manual the pins are swapped out
the manual of your inverter has the pins swapped...
Ok thanks, so stick with what you've said. Basically the same at both ends? CAN L - Blue, CAN H - White / Blue, Ground - Green - Ground? Sorry to sound thick but all this is new to me.
Thank you, really appreciate your help. Should I go for a CAT 6 cable?
it depends where and how long your comm cable will be.
I'll go CAT 6. Am I ok to use CAT 6 for the CT, the CT cable with the inverter isn't long enough, need to go about 18m. Thanks again.
you're welcome and good luck !
Will do and thanks againyou're welcome and good luck !
make sure to set the ct pointing the arrow in the correct direction..

Just done a bit more reading and downloaded the latest 8.8kw manual and now I'm totally confused! Is your 12kw inverter the same as my 8.8 in terms of CAN connection? Only info I can find on the 12 says 4 - CAN H, 5 - CAN L and no other pins used? The diagram looks to have the pin numbers reversed as in the connector is upside-down so pin 1 is pin 8. Really don't know what i'm doing with this!you're welcome and good luck !

all comm board are the same, i told you already that in the manual hi and low are swapped.
Sorry, i just don't understand why pins 4 and 5 have to be swapped over at the inverter end. SunSynk 8.8 inverter states Pin 2 is Ground, Pin 4 is CAN H and Pin 5 is CAN L. Battery says Pin 6 is Ground, Pin 4 is CAN H and PIN 5 is CAN L. So surely a case of making a lead with three wires but Inverter 2 to battery 6, Inverter 4 to battery 4 and inverter 5 to battery 5. Or are you saying this is wrong and the battery / inverter info is incorrect and 4 and 5 need swapping over at the inverter endall comm board are the same, i told you already that in the manual hi and low are swapped.
pin 3 and 6 are ground, which is required for the seplos.
as my rs485 needs ground too, i choose to use pin 3 ground from my rs485 and pin 6 for my canbus.
this is now the third time i told you the same, and i consider your question answered
if indeed you have an 8.8 is will be the new generation, and above will apply.
It was purchased as an 8.8 a few weeks ago, model number is SUNSYNK-8K-SG01LP1-EU so assuming a new generation then no need to swap pins 4 and 5?
a new device and next generation arent the same thing.
Totally get that, wonder if the serial number will help identify it.
Thanks for posting the configuration. I am about to have a Sunsynk 5.5 ECCO commissioned and noticed that the yellow Comms cable to the battery (also a Seplos) is not marked at either end as shown in the manual, so I was a little confused as to its orientation. I will make up an additional Comms cable exactly as you have and hopefully it will connect correctlybattery end , normal utp connection
