I have two Victron 250/60 controllers on my house system.  
The first was installed in mid 2022 and has/is working  
flawlessly.

The second controller I bought as a spare in the event  
something happened to the first controller. However.  
in October last year, 2025, I installed more solar on the roof  
and used my spare 250/60 controller on the second array.  
When originally installed, all worked fine and the bluetooth  
was operating as it should. But, in January this year, 2026, after  
working for three months the bluetooth has stopped working  
on this controller. It is still performing it’s controller function.  
I have 5 other Victron devises that have BT and are working  
perfectly.

Appreciate any positive input on this.  
Bluetooth has ceased to function.

Have you tried disconnecting it from pv and battery (waiting 3 minutes) and reconnecting it to see if it wakes up again?

No, I disconnected the the solar but not the battery. I will do that. Thanks.
