The Prostar 15 is a no-nonsense charge controller for good money. I have been using mine for a few days with a 100w solar array. I installed it in a matter of minutes on my boat. It gives off no noise or interference (I mounted it a couple feet away from my radios). There are many other chargers out there, but for the intended application, the Prostar is a solid choice at a great price.

Can I just leave the Load side of the controller unconnected?
The use of those connections is optional, just leave them if not needed.
Can this be used outdoors, will it handle occasional rain?
We do not recommend this, because this charge controller is not waterproof.
