Solar charge controllers generate heat as they regulate voltage and current. However, overheating is a common issue faced by. . 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. I took it loose and found that whoever attached the wires to it was cutting copper strands to slip them into the terminals instead of opening the screws up fully on the terminal. The SC will use whatever current necessary to charge the batteries and run the running 12v loads but it has to dissipate the unused current somehow and that is via. . How hot is your charge controller? I'm getting really high temperatures on my MPPT 150/100Tr in the 75 degree Celsius range when at full load.
