MC4 to Anderson: How to Connect Solar Panels to Goal Zero
Goal Zero built its reputation on rugged, easy-to-use power stations, but the connector it chose for solar input trips up a lot of new owners. Most Goal Zero Yeti units accept solar power through an Anderson Powerpole port (and on some models an 8mm barrel), while the vast majority of foldable solar panels on the market, including the larger SunJack panels, output through MC4 connectors. If you already own an MC4 panel and a Goal Zero, you do not need to buy a whole new panel. You just need the right adapter.
This guide walks through what each connector is, how to bridge MC4 to Anderson safely, and the specs that actually matter so you do not lose power or risk a bad connection.
MC4 vs Anderson: two very different connectors
It helps to know what you are joining. An MC4 connector is the round, threaded connector you see on almost every rigid and foldable solar panel. It twists and locks together, is weather-sealed, and is the de facto standard for solar output. MC4 connectors are polarized by design: one is male, one is female, so you cannot reverse polarity by accident.
An Anderson Powerpole is a flat, genderless connector. Two identical housings slide together, which is why Anderson is popular in the radio and mobile-power world. Goal Zero adopted a Powerpole-style input on many Yeti models, including the high-power input on larger units.
| Connector | Shape | Polarity | Common use |
|---|---|---|---|
| MC4 | Round, threaded, locking | Polarized (male/female) | Solar panel output |
| Anderson Powerpole | Flat, genderless | Set by housing orientation | Goal Zero solar input |
How to connect an MC4 panel to Goal Zero
The cleanest path is an MC4-to-Anderson adapter cable: MC4 male and female on the panel side, an Anderson Powerpole on the Goal Zero side. You plug the adapter into your panel's MC4 leads, then plug the Anderson end into the Yeti's Powerpole input. That is it.
Pick the right wire gauge
Wire gauge matters more than people expect. Thinner wire means more voltage drop, especially over a long run or at higher current. For most foldable panels up to roughly 100W, a 14AWG MC4 adapter cable is a great balance of flexibility and low loss. If you are running a higher-wattage array or a longer distance, step up to the heavier 12AWG MC4 adapter cable, which carries more current with less heat and less loss.
Confirm your Goal Zero input first
This is the step most people skip. Goal Zero has changed solar input ports across model years and product generations, and not every Yeti uses the same Anderson layout, while some smaller units use an 8mm barrel instead. Always confirm the actual input port on your specific Goal Zero model and year before you buy an adapter. Check the port itself and the manual rather than assuming, because guessing here is the number one cause of returns.
Watch your voltage and current limits
An adapter only changes the connector, not the electrical limits of your gear. Make sure your panel's open-circuit voltage and short-circuit current stay within what your Goal Zero's solar input accepts. If you plan to combine panels to hit a higher wattage, you will typically wire them in parallel with a splitter so the voltage stays the same while current adds up. A Y-branch parallel splitter handles that, but always verify the combined current stays under your power station's rated input.
Still not sure which adapter you need?
If the alphabet soup of connectors has you second-guessing, our solar adapter guide breaks down MC4, DC5521, Anderson, XT60 and barrel plugs in plain language, with examples of which devices use which connector. You can also browse every cable and tip in one place at the SunJack adapter collection.
The bottom line
Connecting an MC4 solar panel to a Goal Zero is genuinely simple once you have the right MC4-to-Anderson adapter and the correct wire gauge for your wattage. The only real homework is confirming the exact input port on your specific Goal Zero model and year, because that detail varies. Get that right, choose 14AWG for typical panels or 12AWG for heavier runs, and your existing panel will charge your Yeti without buying a whole new kit.
