Solar Panel Wiring To Charge Controller

Wiring diagram of solar panel with battery inverter charge controller and loads.

Solar panel wiring to charge controller.

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. 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 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.

It regulates the voltage and current coming from the solar panels going to the battery. 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. 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.

Usually 12 24 or 48 volts. Enter solar panel output voltage. A charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging. 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.
