VE.Can SmartSolar not showing up in Cerbo GX

Hi,

I have a new setup which is failing to establish VE.Can communication with Cerbo GX and SmartSolar MPPT 250/100 MC4 VE.Can. The solar chargers are neither visible on VRM or in Cerbo GX console.

I want DVCC in use, in order to scale up with additional solar chargers while having a system-wide max charging current defined.

Please help - I'm running out of ideas. How can I get the Can devices visible? I have terminated the Can bus in both ends.


Br,

Kristian

Hi @kickus

The cable you are using between the MPPT and GX device is a special and specific cable that is intended only for BMS-Can devices.

Replace it with a regular RJ45 CAT5e or CAT6 networking cable and it should work as expected.

You can tell by those white text labels at the ends.

Big thanks, that explains it! I’ll replace them and will accept the answer once I’ve confirmed the success.

Thanks a lot, your advice solved my problem. I had missed that it was a non-standard ethernet cable, I had accidentally ordered them as VE.Can cables. Now my SmartSolar charge controllers are showing up in VRM as expected. 1720699625948.png
