New installation, details of the system:
Multiplus II 48/5000 connected via VE.bus
Pylontech batteries connected to the Cerbo via BMS-can
Multiplus is behaving strangely...
Multiplus goes from inverting to off and then back again to inverting in intervals of 7-15 seconds ...
Cerbo GX shows multiplus status and it goes from inverting to unknown then back again to inverting and back to unknown. There is nothing connected to the AC out except one lightbulb I connected for testing, and there is no AC in.
I tried different UTP patch cable, both are premade patch cables, same brand different lengths. Multiplus continued to go on and off.
When disconnected from Cerbo GX Multiplus works normally (inverting).
I also connected to the Multiplus through the MK3 interface from my android phone, It also continued to work normally.
In the end I connected MK3 interface directly to the Cerbo via USB and the Multiplus works normally, and also is shown in the Cerbos interface. I used the third patch cable (different brand) with MK3 interface. This patch cable was too short to reach Cerbo directly.
Could this be because of the faulty patch cable? Or is there something else that I am missing?
