Victron 100/20 MPPT almost caused fire. battery terminal gave 80v , same as PV side

I have a new 250/60-Tr SmartSolar MPPT. Does anyone know if it has the built-in short relay to protect against PV voltage short to battery voltage? I would love for Victron to confirm this. I am sure a lot of owners of Victron MPPT’s are nervous now! My system is installed at a remote cabin so I cannot be onsite regularly.
