Solar Panel Wiring To Charge Controller

Enter solar panel output voltage.

Solar panel wiring to charge controller.

Enter the total amps that your solar panels will produce all together. A solar charge controller is designed to receive power from a solar panel or array of panels and use it to charge a battery or bank of batteries. A charge controller is a determining factor when it comes to solar panel wiring. Enter the distance in feet from your solar panels to your battery bank 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. Usually 12 24 or 48 volts. This involves varying charge stages voltages and current depending on the type of battery and other factors. Most 12 volt panels put out about 16 to 20 volts so if there is no regulation the batteries will be damaged from overcharging.

The charge process is performed in a smart or intelligent way. If you have any dc load then you can connect it to the output of the charge controller. Click on calculate to see the size wire required in awg american wire gauge. As you see in the connection diagram at first the solar panel is connected to the solar charge controller and then a 24v battery is connected to the charge controller.
