4MM BRANCH CONNECTORS COMPATIBILITY

Solar Panels: Boulder 100i, Flex 100i and other Goal Zero solar panels with MC4 connections.
Yeti Power Stations(MC4 to HPP adapter also required)

Yeti 1000C, 1000X, 1500X, 3000X, 6000X, Yeti PRO 4000, and any other Yeti Power Station with HPP solar input.

When would I need to use a Solar Branch Connector?

When assembling a larger solar panel system (4+ panels) using Boulder 100i, Flex 100i, or other Goal Zero solar panels with MC4 connections
When connecting solar panels with MC4 connections to Yeti X-line power stations. Chain two panels together in series using the attached cables. Then chain in parallel using a solar branch connector.
When connecting solar panels with MC4 connections to Yeti PRO 4000 power stations. Chain up to five panels together in series using the attached cables. Then chain in parallel using a solar branch connector.

Example setup using eight Boulder 100i solar panels (800 watts of solar):

Chain two Boulder 100i panels in series using the cables attached to the solar panels (create four of these two panel sets)
Connect each of the two panel sets to the 4-1 Solar Branch Connector. Plug the positive connector from each set into the respective positive connector of the 4-1 Solar Branch Connector. Repeat for each of the negative connectors.
Connect the positive and negative connectors from the 4-1 Solar Branch Connector to the MC4 to HPP adapter.
Plug the HPP end of the MC4 to HPP adapter into the HPP input on a Yeti Power Station.

NOTE: Each set of panels connected in series should have the same number of panels and be the same model.

I picked up this 4MM BRANCH CONNECTOR to expand my setup beyond a couple of panels. It includes both the female to male and male to female 4 mm branch connectors, so I could wire two strings in parallel after chaining panels in series. I use it with Boulder 100i panels, and the fit on the MC4 connections is solid. Note that for Yeti power stations with HPP input you still need the MC4 to HPP adapter, which is worth knowing before ordering. Handy little part for going from 4+ panels to 800 watts.
