Solar Panel Wiring To Charge Controller

Maximum power point tracking mppt charge controllers are for wiring solar panels in a series where pulse width modulation pwm charge controllers are used to wire solar panels in parallel.

Solar panel wiring to charge controller.

It regulates the voltage and current coming from the solar panels going to the battery. Enter solar panel output voltage. The charge process is performed in a smart or intelligent way. This involves varying charge stages voltages and current depending on the type of battery and other factors.

Enter the distance in feet from your solar panels to your battery bank charge controller. Usually 12 24 or 48 volts. If you have any dc load then you can connect it to the output of the charge controller. Enter the total amps that your solar panels will produce all together.

Click on calculate to see the size wire required in awg american wire gauge. Most 12 volt panels put out about 16 to 20 volts so if there is no regulation the batteries will be damaged from overcharging. A charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging.
