Exceeding voltage or amps on SCC | DIY Solar Power Forum

If your panels are making 100 amps and your Charge Controller ISC limit is 15 Amps then I do not recommend doing it. The way around it is to put your panels in series which boosts the voltage and also keeps the current low. Wattage is a simple Volts times Current. So if you have 350 volts and 15 amps for the panels then you have 5250 watts.
