Per the cerbo manual, it seems that this is automatic with no way to disable it. We are manually setting the charge values on the mppts.
ve.can profile is set to "ve.can & can-bus bms 250 kb"
BMS-Can port Disabled
DVCC - Disabled

We just installed several 450/200 mppts. Is there a way to stop them from auto sychronising.
MPPT connected via VE.CAN phase sync by default. Don't know that it can be disabled.
Even with this feature, all MPPT must be set to the same charge values.
Synchronised charging - All chargers in the network will act as they were one large charger. One of the chargers in the network will assume a master role and the master will dictate the charge algorithm the other chargers will be using. All chargers will follow the same charge algorithm and charge stages. The master is selected randomly (not user settable) so it is important that all chargers use the same charge settings. During synchronised charging each charger will charge up to its own maximum charge current setting (it is not possible to set a maximum current for the whole network).
If you connected them all via VE.Direct, there would be no sync between them.
Thank you for the help. I reviewed the manual several times and sought an answer concerning the sync function. It was odd as they did not sync for four days of usage until a firmware update on the cerbo yesterday evening. I ordered the direct cables, and they will arrive Friday.
