Simply Unbeatable | More Power in Less Space

We recommend a variation of these Y-branch connectors when wiring your panels in parallel as they serve to simplify your wire runs, ease installation and provide a good connection and have a weatherproof seal (IP67) to withstand the outside elements.

 

They are each sold in pairs and are very easy to connect together (plug and play) with MC4 connectors on the end.  Designed not to pull apart you will need an MC4 tool to remove them, available in our shop.

 

Choose 2-1 for wiring 2 panels in parallel

Choose 3-1 for wiring 3 panels in parallel (*and order 3x in-line MC4 fuses

Choose 4-1 for wiring 4 panels in parallel (*and order 4x in-line MC4 fuses)

 

*Over Current Protection (OCP) is required with an appropriately sized in-line MC4 fuse to each panel (positive) because when wired in parallel the combined panels current (amps) may exceed the Series Fuse Rating for a single panel.  The Series Fuse Rating varies with each panel but is either 15A, 20A or 25A (check panel spec sheet).
