All Victron charge controller stopped charging at the same time! A major freak out of the system resulting in 0A going into the battery. Of course, this happens when you're not at home. Thanks to the Victron VRM, I could get access to the controllers and found that they all show -1°C which caused them to stop charging.
Back in the garage, I could do some troubleshooting and fault finding. I could get 3 out of 4 controllers working again but the main MPPT did not want to play the game and refused to start charging. And it has this funny smell...
A big thanks to the Victron Team for replying so quickly and helping me out here (even on a Sunday).
Someone else had a similar issue with one of the Victron Solar Charge Controllers and a negative temperature glitch:
