Incorrect temperature creates errors, shuts my system down.

Victron 150/70MPPT, Multiplus 24/3000/70, BP220, BMV712, CerboGX. For instance BMV712 yesterday shows -27 F, the Cerbo touch screen showing many temperature warnings of -41 C. I can't figure this out. Out the of country for a week and system shut down. Received warning email from VRM Notifier of battery low temperature. Ambient temps are 50-90 degrees.

I'd look for an open circuit / loose connection or frayed wire in the temperature sensor..
