Connecting 4 charge controllers

Hi , we have connected multiple charge controllers MPPT 250/100 to gerbo 3x ve direct cables at multiple installations. Runs like a dream.


We need to connect 4 x 250/100 mppt via ve can.

Can we please have the gerbo settings and wiring diagram to connect to gerbo GX. We have all cables and terminators.


Regards

André

Uhm, CAN devices are daisy chained with a terminator on either end of the chain. This should already be documented in the cerbo manual, not that it is complicated.

Sections 2.4.3 and 2.4.4

If you have used the ve.can port, it should just work. Ve.can will already be at the right baud rate.screenshot-2023-02-19-at-154515.png

Just check no one has fiddled with the port settings.

And try some other RJ45 cables.
