Nanuk 903 Waterproof Case - SOLAR READY

The Nanuk 903 Waterproof Case is modified by our Voltaic team to easily connect our solar panels to the batteries inside the case, without compromising the waterproof seal.

Comes with a solid foam core with removable inserts. Customize the interior to fit your Voltaic battery, cell phone, and other electrical devices.

Recommended for 6 Watt or 9 Watt Solar Charging Kits. Solar charging kits using a V72 Laptop Battery need to use the Nanuk 904 Waterproof Case.


Connecting to a solar panel
  • Remove any adapter from the solar panel cable or extension cable if there is one
  • Plug the solar cable into the female plug on the back of the Nanuk case, pushing it all the way in so that both ridges on the solar cable are covered
Connecting to the battery on the inside of the case
  • Connect the internal cable into the Voltaic battery (V15 or V44 Battery recommended)
Customizing Foam Insert
  • Lay battery on top of full foam insert to plan where it should go
  • Use a sharp knife / box-cutter / scissors to remove foam around the edges of the battery so it will fit securely
  • Once the edges are cut, use horizontal cuts inside the foam to remove the entire layer foam from the insert
  • If battery is positioned on top of the foam (recommended) cut an additional cavity underneath the battery to store your cell phone
