Notes from the Installation Team
We frequently use SunGuard controllers on small solar modules. The controller is well built and rock solid. The controller has a small footprint ot 2" square (2.5" including mounting tabs) and 1.5" deep. It has four leads that emerge from the epoxy encapsulation. Two leads for solar and two leads for the battery. The bottom of the controller has two small triangular shaped tabs with holes in them for mounting.

I have Morningstar SunGuards on various sizes of small modules that I use for keeping the batteries charged on the plow truck, my boat and my hunting camper. I have been using them for years and find them to be very reliable and rugged. From first hand experience we can recommend this product for small solar battery charging applications.

What you need to Acquire
1 - Automotive type ATC fuse link and fuse sized for your solar module
1 - Length of 16 gauge AWG (or larger) two strand wire for running charge circuit from controller to battery
2 - Ring terminals or alligator clamps for battery connections
