Learn how to connect an 8mm solar panel to a Yeti PRO's HPP port using the 8mm to HPP Solar Adapter, with step-by-step instructions and common mistakes to avoid.

Quick Answer

To use the 8mm to HPP Solar Adapter, plug the 8mm end into your solar panel, connect the HPP end to your Yeti PRO's HPP input, and ensure the panel is positioned in direct sunlight. This adapter lets you use older 8mm solar panels with newer Yeti PRO models that lack an 8mm port.

Why Use an Adapter Instead of a New Panel?

If you already own a Goal Zero 8mm solar panel, like the Nomad series, you don't need to buy a new panel when upgrading to a Yeti PRO. The 8mm to HPP Solar Adapter bridges the gap, letting you keep your existing gear while enjoying the faster charging and expanded input options of the HPP port.

Keep in mind that the adapter is rated for 18 amps and 16 AWG, so it's designed for low-power 8mm panels. If you plan to use a high-wattage panel, check that the adapter's rating matches your panel's output to avoid overloading the connection.

Step-by-Step Setup

Check compatibility: Confirm your solar panel uses an 8mm output and your Yeti PRO has an HPP input. The adapter is designed for Goal Zero Portable 8.0mm panels, but other 8mm panels may work if they meet the 18A limit. If your panel draws more than 18A, do not use this adapter—look for a higher-rated solution.
Connect the adapter to the panel: Plug the 8mm female end of the adapter into your solar panel's 8mm male output. Make sure it's fully seated to avoid a loose connection. A loose connection can cause intermittent charging; give it a gentle tug to verify it's secure.
Connect the HPP end to the Yeti PRO: Insert the HPP male connector into the HPP input port on your Yeti PRO. You should feel a click when it's properly locked in place. If it doesn't click, the connector may be upside down—rotate and try again.
Position the panel in direct sunlight: Place your solar panel outside in direct sunlight, angled toward the sun. Avoid shaded areas or glass obstructions that reduce efficiency. Check the Yeti PRO's display to confirm input wattage; if it's zero, reposition the panel.
Monitor charging progress: Watch the Yeti PRO's input indicator to ensure it's charging. The adapter supports up to 18A, but actual charge rate depends on panel output and sunlight. If charging is slower than expected, clean the panel surface and adjust the angle.
