MPPT Synchronized Charging

I read a discussion topic on this board that stated that the bluetooth enable ve.direct mppt controllers were due to get a synchronization feature a while back. Did this ever happen? If not, is it still being worked on?


Thanks

It is out now, V1.47 adds it to smart devices. Please check Victron Professional or VRM if you have GX device.

Excellent, is it a setup option on the bluetooth setup? And available on all smartsolar mppt controllers? I have 6 75/15 controllers on the way for my new array on my sailboat

Elimac, I see that v1.47 is out, but VictronConnect only upgrades my Blue Solar MPPT 75/15 chargers to v1.46. I have Bluetooth Smart Dongles on each 75/15. Will v1.47 provide better sync in my setup (a always lose one from Bulk charge too early)? Where can I find a guide for downloading and installing v1.47?

The changelog shows that v1.47 sync charging is not applicable for the Blue Solar models, even with Bluetooth Smart Dongles applied. Likewise, the Tail Current improvements to not apply to the 75/xx models. So I don't see any advantage in my case.

- "Add synchronized charging via Bluetooth (for SmartSolar models only)

- Tail current mechanism improved: it can now use the real battery current. The current can be received via VE.Smart Networking (Bluetooth) as well as from a GX Device. Included for all SmartSolars and the following BlueSolars: 100/20, 100/20 48V, 100/30 rev2, 150/35 rev2, 100/50 rev2, 150/45, 150/60, 150/70, 150/85 and 150/100)"

@torrmundi, you're correct, unfortunately the improvements in 1.47 will not benefit you in your application.
