All my controllers are MPPT and I'm familiar with them. My son ordered a 400 watt solar kit with a pwm controller and I have never used one. I assume the panels will be all parallel in hook up. I'm not sure if he is getting a 30 amp or 60 amp controller yet. All I have laying around is 40 amp fuses for the controller to the battery. Should I get a 30 or 60 amp fuse to match the output of a PWM controller? Also the panels are 100 watts each at 5 amps so I'm assuming a 15 to 20 amp fuse from the panels to the controller? Maybe I'll just give him one of my spare MPPT 40 amp controllers! lol
