Attach the solar panel to the mast with the U-bolt 
assembly. The fixed bracket should be flush against the  
U-bolt saddle. 

 

 

Move the solar panel to the position on the mast where it 
will get the maximum amount of direct sunlight over the 
course of the day. Use a ½ inch wrench to tighten the 
flanged nuts on the U-bolt. 

 

 

Plug the cable into the HOBO station’s charging port. 
Refer to the HOBO station user’s manual at 
www.onsetcomp.com/support/manuals for the location
