SmartSolar MPPT 100/50 does not accept PIN

I'm trying to connect a new just installed SmartSolar MPPT 100/50 (part of EasySolar) with bluetooth from a mobile. However, device doesn't accept default PIN 000000 (or 0000 or 12345678 or 123456). Problem still exists after PIN reset with PUK code. There isn't any other bluetooth device nearby. Connecting has been tested with three different mobile phones but issue remains.

Connection works from PC with a VE.Direct cable.


How can I fix this issue? Reseller doesn't reply to my email.

I think the issue is the new update they did to the app. My system worked great until the update. I'm guessing they can't figure out the problem with the update and figure it is easier to just play dumb.

I truly wish I could be more help.

Hi Tony,


What kind of mobile are you using?

And what is happening when you enter the PIN code? Can you describe a little bit more?


Kind regards,

Hi @Thiemo van Engelen (Victron Energy staff),


And thanks for reply! I have tried with Samsung S10, Oneplus 6 and Oneplus 7.

Oneplus 6 gives error: "Unknown error:ff00" and Samsung and OP7 tries to connect and when progress bar reaches 80% it will jump back to 20% and proceed this why infinitely.

If not already done, manually remove the Bluetooth pairing from the mobile phone Bluetooth list, then try to connect again.

Ensure that when you attempt to connect to the MPPT that it's done via the VictronConnect app and not via the mobiles Bluetooth pairing function.

If that fails I would try to power cycle the MPPT next (by temporarily removing battery and PV power).
