Once the fuse holder is in place, don’t attach a fuse just yet. Connect the bare stranded
portion of the cable to the
positive (+) battery terminal on the charge controller.
4. The fuse between controller and battery should be the current rating of the
controller. Once the fuse is properly sized, ensure that all connections were made
properly, and that there are no loose connections present. Finally, insert the fuse into the
fuse holder.
The controller should power on.
5. If opting for no in-line fuse , connect the bare stranded portion of the cable to the positive
(+) battery input terminal on the charge controller directly from the positive (+) battery
post, bypassing the fuse holder. The controller should power on.
Warning!
Be careful not to short the battery. Reverse polarity connection will
damage the charge controller and the resulting damage will not be covered
by warranty.
