Solar Panel To Charge Controller Wire Size

Estimated cable length 12 4m needed for connecting the solar array to the next solar power system unit for the example charge controller.

Solar panel to charge controller wire size.

Enter the distance in feet from your solar panels to your battery bank charge controller. This corresponds to awg gauge 8. Enter the total amps that your solar panels will produce all together. I am sorry but i was not able to add the web sites as cards during the video.

To use the wire size calculator just follow these 4 simple steps. Typically charge controllers come in 12 24 and 48 volts. Clear photos of all diagrams on the facebook page. You typically want to make sure you have a charge controller that is large enough to handle the amount of power and current produced by your panels.

Charge controllers are sized depending on your solar array s current and the solar system s voltage. Enter solar panel output voltage. A typical recommendation is to limit the solar array to 110 125 of the maximum controller rating. If you have 3 solar panels rated at 6 amps each mounted 30 feet from the charge controller then you would move down the chart to 18 amps 3 panels 6 amps and across to 32 5 closest to 30 and then up the chart to 4.

We get calculated that we need a copper wire of 0 128 diameter in inches and a recommended maximum current of 29a defined by choosing solar system voltage. Usually 12 24 or 48 volts.
