Hello at Victron
I'm in search for an answer to my coming combination. Up to now Im using an OPzS System on a CCGX with two MMPTs and three Mulitplus II. One of my MPPTs was defective (VE.bus port failure) and was replaced with a CAN Version of it. As I was replacing the cable I chose (VE.)CAN as my new connection due to the much better possibilities of CAN.
Now I read on some sites that the generic VE.CAN of my CCGX could not cope with two CAN devices (esp. when a BMS is one of them like my planed from Pylontech) on the same bus which puzzles my knowledge so far.
Is there truly a 1 external device limit to the VE.CAN? Usual regulation defines 31/63/127 ext. devices depending on what version of CAN you chose. As I plan to buy another MPPT I'd have chosen the SmartSolar_250_85_CAN as wel due to "one system wide bus" idealogy of CAN. As my VE.direct and VE.Bus is already overloaded this seemed like a good way to expand.
Cheers
Michael
