I clicked the button to update the smart (bluetooth) version of the MPPT 100 | 50 from VRM to 1.68 from 1.67, I got a You don’t have sufficient rights to perform this action. (1512) error and the charger is now offline, not communicating with the raspberry pi. What do I do?
I assume you are running Venus OS on the Pi? And you used VRM to update?
Have you tried restarting the MPPT by disconnecting it from both PV and Battery voltage for 10-20s?
Hi,
I did the update through vrm and it failed with thay error then the charger never went back. The house it’s installed is a 2 hour drive. I went there just now, found it blinking. I didn’t have to turn it off just connected with bluetooth and performed the update. Everything is fine now.
