I just hooked up a Morningstar SunSaver 6 charge controller with my 50W Kyocera panel. The controller has 6 lugs - two for the battery, two for the panel, and two for "load". The first four are obvious. The load lugs have me wondering. Why does the controller want the load connected through the controller? Is this for supplying power to loads in the absence of a battery? The literature didn't explain it.
I didn't hook anything up to the load lugs, and I don't plan to. But my computer scientist crew this weekend had various theories about why he thought it would be more efficient to have all loads going through the controller. (He also spent a while trying to explain to me why the apparent wind created by running the engine, didn't "count" the same way as an apparent wind due to sailing, when predicting whether the wind would still be directly on our nose if we turned 45 degrees. )
Anyways, does anyone have insight into these "load" lugs?
Thanks, Nate
