Just got my Tempest here in the UK, Voltage started off pretty low 2.2V now up to 2.71 what is the max I should see?
Great to see another UK station! 2.7 to 2.8 V is the maximum expected voltage (https://help.weatherflow.com/hc/en-us/articles/360048877194-Solar-Power-for-Tempest)
I have a number of 2.81 volt readings on my station graphs. That’s about the highest I have seen.
Up to 2.79 this afternoon so all is good then.
Reached a maximum of 2.83V in the Netherlands.
