Frequently Asked Questions

How do I connect two Boulder 100i panels with the Goal Zero 4MM branch connector?

Simply plug the male connector of one panel into the female end of the branch connector, and the female connector of the second panel into the male end. This creates a parallel connection, increasing current output. The branch connector's outputs then plug into your power station or charge controller.

What is the Goal Zero 4MM Branch Connector compatible with?

It is compatible with Goal Zero solar panels that have MC4 connectors, such as Boulder 100i, Flex 100i, and Nomad panels (with MC4). For Yeti power stations with HPP input, you'll also need an MC4 to HPP adapter (sold separately).

Can I use the 4MM branch connector with Nomad panels?

Yes, if your Nomad panel has MC4 output, the branch connector works. Most newer Nomad panels (like Nomad 50, 100) use MC4, but older ones may use 8mm connectors. Check your panel's output type.

Where can I buy the Goal Zero 4MM branch connector at the best price?

You can buy it from this online store at $10.00, which is 33% off the $14.95 list price. Use coupon code GRID15 for an additional 15% off. Free shipping applies on orders over $45.

Easy to use

Snapped these onto my panels in seconds. The connectors feel solid and weatherproof. Now I can double my solar input without any fuss. Great product for the price.

Works as expected

These branch connectors are sturdy and connect my two Boulder panels perfectly. The parallel setup doubled my charging speed. The only reason for 4 stars is the lack of instructions, but I figured it out easily.

Fine, but a bit flimsy

They do the job, but the plastic feels a bit cheap. I've had them for a few months and they're still holding up, but I'm not 100% confident they'll last years outdoors. However, for $10, it's not a bad deal.

Must-have for solar setups

If you have multiple Goal Zero panels, these connectors are essential. They allow me to combine my Nomad 20 and Boulder 100 to get faster charging. They clicked in place with a satisfying snap and have stayed put in all weather. Highly recommend.

Not compatible with my panels

I bought these thinking they'd work with my older Goal Zero panels, but the connections didn't match. The female/male ends are the modern type, but my panels have a different connector. Check compatibility first to avoid disappointment.
