ACOPWER MC4 T/Y Branch Connectors — 1 Pair (MMF + FFM) for Solar Panel Parallel Wiring

The ACOPWER MC4 T/Y Branch Connector Pair lets you connect two solar panels in parallel to a single charge controller or power station — no tools, no splicing. Rated at 1000V DC / 600V UL with IP67 waterproofing and silver-plated copper contacts, these are built for permanent outdoor installation. Priced at $46 per pair (1x MMF + 1x FFM).

• Self-Locking PV Connector Compatibility — Designed to mate with standard MC4 (PV) connectors using a key-lock mechanism for instant, secure installation without special crimping tools.
• IP67 Waterproof Rating — Fully sealed against dust ingress and temporary water immersion, making these connectors safe for rooftop, ground-mount, and mobile solar installations exposed to rain and humidity.
• Silver-Plated Copper Contacts — Silver plating reduces contact resistance and resists oxidation over time, maintaining low-loss electrical connections even in humid or coastal environments.
• 1000V DC / 600V UL Withstand Voltage — Rated for high-voltage solar strings, compatible with both residential and commercial PV system voltages without risk of insulation breakdown.
• CE & TÜV Certified — Dual certification confirms compliance with European and international safety standards — required for grid-tied systems and important for insurance and permitting.
• UL94-V0 Flame-Rated Housing — PC/PA insulation material meets the highest flame-resistance classification, self-extinguishing within 10 seconds — critical for rooftop and enclosed installations.
• Wide Temperature Range: -40°C to +90°C — Performs reliably from arctic cold to desert heat without cracking, warping, or losing seal integrity.
• Pair Includes Both Configurations — 1x MMF (two male in, one female out) + 1x FFM (two female in, one male out) covers both the positive and negative legs of a parallel branch connection.
