MPPT Smart Solar 100/50 switches to disabled

I'm running v.1.61 firmware.

Roughly once every 2 weeks it switches to Settings-->Battery-->ChargerEnabled = OFF all by itself

I can remedy it by switching it back to ON - but it's annoying and shouldn't be happening.

Has anyone else had this and solved it?

Hi @Charlie Pank

Is the MPPT also connected to a GX product (Venus GX, Cerbo GX, etc)?

With kind regards,

Hi @Charlie Pank

Did you also change the BLE pincode of the MPPT? Could it be that somebody else is messing with the installation?

Kind regards,

The pin is changed from standard. It is the same pin as the other MPPT (100/30 Smart) in the system. The 100/30 never has the same problem.

Hi @Charlie Pank

The only thing that I can think of that you can try is to power cycle the MPPT by disconnecting it from PV and battery for a minute and then reconnecting it battery first.
