I had a bunch of water in mine the other day and was getting some weird voltage drops on chart
Wf support told me that that was normal and would not hurt anything but I can see your point about freezing I found water in the upper section also but it could of came from my having to tip the pole to access the unit as it is on the end of a 14’ pipe.

Hi, thanks for checking and please keep us posted on any issues. Water between the pole mount and solar panel is expected and not an issue; there are no electrical contacts between the two attachments
