Staubli Evo series mc4 connector 1500 vdc

The Staubli MC4-Evo 2 Series Connector (1500 V DC) is a high-performance, heavy-duty photovoltaic (PV) cable connector engineered specifically for demanding, commercial-scale solar power generation systems. Designed by Stäubli—the pioneer of the original MC4 connector—the MC4-Evo 2 series sets a industry benchmark for reliability, efficiency, and long-term durability in extreme environmental conditions.

Key Features & Benefits

• 1500 V DC Voltage Rating: Fully compliant with modern high-voltage 1500 V DC solar utility and commercial installations, allowing for longer string designs and reduced overall balance-of-system (BOS) costs.
• Superior Efficiency & Low Resistance: Features precision MULTILAM contact technology, ensuring minimal contact resistance, low power dissipation, and maximum energy yields over the system's operational lifespan.
• Rugged & Weatherproof (IP68): Offers an IP65/IP68 ingress protection rating (1 hour at 1 meter), providing complete resistance against dust, dirt, moisture, and temporary submersion.
• High Amperage Capacity: Rated to handle up to 70 A (depending on cross-section and environmental temperature), making it suitable for high-current solar module technologies.
• UV & Chemical Resistance: Constructed from high-grade, flame-retardant polyamide casing (UL94-V0) designed to withstand intense UV exposure, extreme temperatures, salt mist, and ammonia.
• Full Intermateability: Designed to safely pair with original Stäubli MC4 product family connectors, simplifying upgrades and maintenance.
