VE.Direct to synchronise 2 or more Smart Solar MPPT Controllers?

Is it possible to link together 2 or more Smart Solar MPPT controllers using VE.Direct cables, without needing a GX or BMV device? Can they just be daisy chained with identical charge settings to work as one? I have a customer whose system requires 2 MPPT units but he can’t afford a GX or other extra equipment. Or will they possibly work together on their own Bluetooth network?

No, to all of those questions.

To get the mppts to sync with each other over bluetooth, you will need a bmv712 or a Smart Battery Sense. (get a blue one), to provide a master battery voltage/temperature. Smart networking.

Of course, you can use the mppts without requiring syncing.

Thanks for the info. I have a spare black smart battery sense unit, so maybe that will help get them both working together in a similar fashion to each other.

Will they synchronise over VE.Direct when a Cerbo GX or similar is in the system?
