How Do I Connect Two Boulder 100i Panels with the Goal Zero 4MM Branch Connector?

Run each panel's MC4 output leads into the branch connector's two input legs, then connect the single combined output to your Yeti's solar input (using the MC4-to-HPP adapter for HPP-input Yeti stations). Parallel wiring keeps voltage constant while adding panel amperage for faster charging.

What Is the Goal Zero 4MM Branch Connector Compatible With?

• Solar panels: Boulder 100i, Flex 100i, and other Goal Zero panels with MC4 connections
• Yeti power stations: Yeti 1000C, 1000X, 1500X, 3000X, 6000X, Yeti PRO 4000, and any Yeti with HPP solar input (MC4-to-HPP adapter also required)

Can I Use the 4MM Branch Connector with Nomad Panels?

Yes — any Goal Zero panel with 4mm MC4-style connectors, including compatible Nomad panels, can be paralleled with this branch pair.

4MM Branch Connector Specs and Wiring

Includes one female-to-male and one male-to-female 4mm branch connector for a complete parallel pair. Wire panels in parallel to combine current at the same voltage; confirm your Yeti's input amperage limit before adding panels.
