Collection: Connectors

Connectors for the solar side and for power links: Redarc SRC0001-CK MC4 connector kits with positive and negative, Redarc SRC0006 MC4 Y adapters rated 30A for paralleling two panels, and Victron Energy solar connectors and adapters.

MC4 is the de facto standard in solar: IP67 sealing, low resistance contact and protection against accidental touch. It gets crimped with the proper tool, not screwed up tight: a sloppy crimp is the commonest cause of hot spots and arcing on a roof.

Y adapters put two strings in parallel, which doubles the current: check that the declared rating covers the sum of the two string currents.
