Renogy MC4 Y Branch Connectors (MMF+FFM Pair)

Renogy MC4 Y Branch Connectors (MMF+FFM Pair)

The Renogy MC4 Y Branch Connectors are the simple, reliable way to connect solar panels in parallel and maximise your energy output. Supplied as a pair — one MMF (male-male-female) and one FFM (female-female-male) — they let you combine two panels into a single line, keeping voltage matched to your battery configuration while eliminating messy, tangled wiring for a clean, seamless solar setup.

Effortless Parallel Connection

Join two panels into one output run in seconds. Parallel wiring keeps voltage the same while increasing current — ideal for adding capacity to an existing array. Just press the built-in lock on the male connector for a secure, tool-light connection.

Weatherproof & Durable

IP67 waterproof protection (when mated) and a PC housing with resistance to oils and high temperatures stand up to harsh outdoor conditions. High aging resistance and UV endurance make these connectors dependable for long-term, permanent installations.

Certified Safety

TÜV and CE certified, with Class II protection and a UL94-V0/5VA flame rating, silver-plated copper contacts for excellent conductivity, and low contact resistance for minimal power loss.

Technical Overview

What’s in the Box

• 1 x MMF Y Branch Connector (male-male-female)
• 1 x FFM Y Branch Connector (female-female-male)

Important Note

Use Y branch connectors only for wiring panels in parallel, and ensure the combined current stays within your cable and charge controller ratings. Confirm your controller can handle the combined array current before adding panels. To connect three or four panels in parallel, use the corresponding 3-to-1 (MMMF+FFFM) or 4-to-1 branch connectors instead.
