How to wire you solar panel to your charge controller.

Refer to the installation material for the charge controller you chose when selecting the correct wire size to use. How to bypass the solar charge controller. A charge controller is a determining factor when it comes to solar panel wiring. Otherwise on sunny days the solar panel may produce more energy than your battery can handle which can damage the battery.

Click on calculate to see the size wire required in awg american wire gauge. 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. I get asked all the time if someone can connect their inverter directly t. Voltage drop in a single panel system as you can see in the calculation the voltage drop is 4 09 which will reduce the overall power delivered to the charge controller.

The wires between batteries in a battery bank tend to be the largest in the system since they are used in conjunction with a power inverter that can at times demand more current than that the pv system can supply on its own. For instance if you have one of our 40amp charge controllers we would recommend using an 40amp fuse the second fuse between your solar panels and charge controller is a little bit different to figure out.

Enter the total amps that your solar panels will produce all together. For example your solar panel delivers 18 volts dc and 5 8 amps to the charge controller and the wire length is 40 feet.

Enter the distance in feet from your solar panels to your battery bank charge controller. By doing so i can easily connect and disconnect the panels from the charge controller.
