Learn how to safely extend your Yeti solar setup with a High Power Port extension cable. Step-by-step instructions, common mistakes, and practical tips.

Quick Answer

To extend your solar panel's reach, connect the High Power Port extension cable between your panel and your Yeti power station, ensuring all connections are snug and the cable is protected from damage.

Why Use a High Power Port Extension Cable?

The High Power Port (HPP) extension cable is designed to add 30 feet of length to the charging cable of compatible solar panels like the Boulder 200 Briefcase, Nomad 200, or Ranger 300 Briefcase. This is especially useful when you need to position your solar panel in full sun while keeping your Yeti power station in a shaded or more convenient location.

Using an extension cable gives you flexibility in how you set up your solar array, but it also introduces a few considerations. The cable is 12AWG, which is thick enough to minimize power loss over the added distance. However, you should always check that all connections are secure and that the cable is not damaged before use.

Compatibility and Limitations

This extension cable is specifically designed for use with the Boulder 200 Briefcase, Nomad 200, and Ranger 300 Briefcase. It features a High Power Port input and a High Power Port output, so it will not work with panels that use a different connector type.

If you are using a different solar panel, you will need to check whether it has a High Power Port output. If not, this cable will not be compatible without an additional adapter. Always verify your panel's connector type before purchasing or using this extension.

Step-by-Step Setup Guide

Verify Compatibility: Check that your solar panel is one of the compatible models (Boulder 200 Briefcase, Nomad 200, or Ranger 300 Briefcase) and that it has a High Power Port output. Using it with an incompatible panel will not work. If your panel uses a different connector, this cable won't fit without an adapter.
Connect the Extension Cable to the Solar Panel: Plug the High Power Port input of the extension cable securely into the High Power Port output on your solar panel. Make sure the connection is snug and fully seated to avoid intermittent power loss. A loose connection can cause voltage drops or arcing—always double-check the fit.
Connect the Other End to Your Yeti Power Station: Plug the High Power Port output of the extension cable into the High Power Port input on your Yeti power station. Ensure the connection is secure before proceeding. If the connection feels loose, reseat it to avoid poor contact.
Route the Cable Safely: Lay the cable along a path that avoids sharp edges, foot traffic, or areas where it could be pinched or crushed. Use cable clips or stakes if needed to keep it out of the way. Protecting the cable from physical damage extends its life and prevents safety hazards.
Test the Connection: Once everything is connected, check your Yeti power station's display to confirm that solar input is detected. If no input appears, disconnect and reconnect each end, checking for debris or damage. If solar input still isn't detected, inspect the cable for cuts or kinks and replace it if damaged.
