I have a 40A MPPT HQST charge controller. Got it during raining season so it wasnt really getting full power from my Panels. Was pushing out about 15A to my 12v 200ah battery. Now raining season is off and it has started outputting about 38, 39A. Meaning it is working at full power. I noticed it was quite warm to the touch from the front, then I touched it from the back and this guy burnt my hand. It was extremely hot. Is this how SCC works when they work at maximum power? Is it supposed to be that hot? I was even planning to over panel for when rain starts again but with the way the controller is currently very hot, now that there is full sunlight, I am afraid to do it. Is this the normal way SCC get very hot when they are outputting peak power? And can I still overpanel the Charge controller. Was planning to add one more panel to it for days there isnt enough sun when I usually get 15A which is too small for my battery.
