I have a Smart Solar MPPT 75/15 controller. I've been using it all summer and it's been great. Now however, I've noticed that I'm not getting an output on the 'load terminals'.
I have set the load to be 'always on' in the app, but I'm just not getting anything out of it. And even the app both iOS and in MacOS show the load output to be 'off' even though I've turned it on.
A quick test with a multimeter confirms it's off as in there is no voltage.
Is there anything I should check, possibly an internal fuse, or should it be returned?
