The 6616 extra solar power kit is intended for adding to a 6612 or 6614 unit to provide extra charging capacity in locations where winter sunlight may be limited, by giving a total panel power of 10W. A suitable connecting cable is supplied. It is based on the 6618 universal shelter for use at unattended remote sites where there is no mains power and it's impracticable or undesirable to visit the site often to replace batteries.
The shelter is designed with a hinged front door with a rubber seal and with two small grommeted cable access ports in the bottom of the compartment. U-bolt fixings are provided top and bottom to allow the shelter to be secured to a vertical pole (or, alternatively, fixed back to a flat surface).
