Hi - I have a 6000XP with an Indoor Wallmount in a cold environment.
Overnight when the temp, of both battery & controller, drops below 32°F the reading spikes to something near 500°F, the charge controller close to 120,000°F.
Obviously it's a bug, but I'm concerned that the heaters may not be running at this time if the system thinks it's above 32°.
In the Bat Temp chart attached you can see the temp spikes overnight. Once the solar panels start producing energy in the morning, it seems to read properly.
