My small power pack will sit in my storage shed for days, sometimes weeks without me using it, so I started investing in 4" 12VDC fans. Their size was determined by the dimension of the air vents. The fans are medium-duty, use 350mA each, and cost $15. Connected to the charge controller's LVD, they draw air 24/7. For the long periods that I don't work in my shed, the 85 Watt panel is able to keep the bank topped off, and exchange the air simultaneously.

While I don't feel a 'breeze' inside my shed, the draft from the outside vents is significant. It makes me feel better about my property sitting in the heat/humidity of SW Texas.
