Only needed when building a larger solar panel system (4+ panels) using Boulder 100i, Flex 100i or other Goal Zero Panels with MC4 connections For Yeti X-Line power stations, you can chain 2 of these panels together in series (using the cables attached to the panels) before you need to chain in parallel via a Solar Branch Connector For Yeti PRO 4000, you can chain up to 5 of these panels together in series (using the cables attached to the panels) before you need to chain in parallel via a Solar Branch Connector

Chain 2x Boulder 100i panels in Series using the cables attached to the solar panels (create 4 of these 2x panel sets) Connect each of the 4 panel sets to the 4-1 Solar Branch Connector (the Positive connector from each set plugging into the respective positive connector of the 4-1 Branch Connector; Repeat for each of the Negative connectors) Connect the positive and negative connectors of the 4-1 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 Series connected panels should have the same number of panels and be the same model
