Staubli MC4 EVO 2 1500V

Staubli MC4 EVO 2 1500V is a high-quality solar PV connector designed for modern high-voltage photovoltaic systems.

Each pair includes one female (PV-KBT4-EVO 2/6I-UR) and one male (PV-KST4-EVO 2/6I-UR) cable coupler, rated for up to 1500 V DC and 45 A. These original Staubli connectors use patented MULTILAM contacts for extremely low contact resistance (under 0.2 mΩ), ensuring efficient power transmission with minimal losses.

The robust, weatherproof design (IP65/IP68 rated) withstands harsh environments, and all units are IEC/UL certified for safe PV installations (tool-required disconnection per NEC 2023).

Sold in cartons of 400 pairs (MOQ 1 carton), the Staubli MC4 EVO 2 provides engineers and installers with genuine, durable connectors for reliable PV performance.

Staubli MC4 EVO 2 1500V (ST-MC4 EVO 2)

• The MC4-EVO 2 is the latest addition to the Multi-Contact PV connector portfolio.
• Internationally certified with IEC, UL, JET, cTÜVus
• MULTILAM Technology, has proven the quality and durability several 100 million times since 2004
• Suited for all climatic environments thanks to resistance to UV, ammonia, salt-mist spray and high IP class (IP68)
• Available as a field and preassembled connector, MC4 tools can be used

Key Features

• 1500 V DC Rating: Certified for up to 1500 V DC (IEC/UL/JET) to support high-voltage PV arrays. (NEC 2023 compliance requires a tool for safe disconnection.)
• High Current Capacity: Rated up to 45 A (IEC) per connector, enabling long PV strings and higher power throughput.
• MULTILAM Contacts: Built-in MULTILAM spring contacts ensure multiple, high-pressure contact points, yielding ultra-low contact resistance (≤ 0.35 mΩ). This minimizes power loss and heat generation even at high currents.
• Durable Construction: IP65/IP68 waterproof and dustproof (mated). UV- and ammonia-resistant materials protect against extreme weather, making the connectors suitable for harsh climates.
• Industrial Certifications: TÜV/IEC certified and UL-listed for PV use. Each connector meets Class II insulation and safety standards.
• Easy Installation: Field-assembled via standard crimping tools (as per Stäubli’s instructions). The connectors are complete and pre-assembled – simply insert stripped cable, tighten housing, and lock.
• Secure Locking: Robust latch with locking mechanism prevents accidental disconnection (do not disconnect under load).
• Genuine Staubli MC4: Authentic Original MC4 connector (protected Stäubli trademark). Ensures full compatibility and avoids counterfeit parts.

Main Benefits

Solar PV System Engineers

Engineers designing large solar arrays benefit from the Staubli MC4 EVO 2’s 1500V rating. This allows longer series strings and simpler system layouts.

The connector’s MULTILAM design reduces voltage drop and heating, so panel output is fully utilized and energy yield is maximized. Its proven durability (hundreds of millions of installations worldwide) and UV-resistant housing ensure long life in all climates, lowering maintenance needs.

Compatibility with IEC/UL standards and the NEC 2023 tool-disconnection feature means systems meet code and work seamlessly with high-voltage DC breakers (MCCBs). In short, engineers get a high-performance, low-loss MC4 connector that maintains efficiency and safety in 1500V PV systems.

EPC Contractors

EPC contractors rely on safe, easy-to-install components. The Staubli MC4 EVO 2’s screw-on assembly (using standard crimp tools) speeds up field installation without special equipment. Because these connectors are genuine Staubli MC4 parts, contractors avoid issues related to cheap knockoffs.

The robust locking latch and IP68 rating ensure connections stay secure over time, reducing callbacks due to failures. The high 1500V DC rating means fewer junction boxes and breakers are needed for the same power, cutting balance-of-system costs.

Additionally, international certifications (IEC, UL, TÜV) simplify approvals and guarantee safety, giving contractors confidence that the PV array will perform reliably for decades.

Electrical Distributors

Wholesale distributors appreciate that the Staubli MC4 EVO 2 is a flagship, trustworthy product with broad market demand. Stocking genuine Staubli connectors means offering a standard solution expected by solar installers and EPCs worldwide.

The product’s strong brand and extensive field use (Original MC4 is the most-installed PV connector) translate into steady orders. Distributors can highlight the high-quality certified features (1500V rating, UL listing) and sell the connectors in convenient cartons of 400 pairs to meet project needs. This reliability and backing by a global company make it a safe, profitable item to stock.

Residential End Users

Homeowners and small installers benefit from the peace of mind the Staubli MC4 EVO 2 provides. Using genuine, high-quality MC4 connectors means fewer surprises: connections remain tight over years without overheating or corroding.

The weatherproof design ensures even exposure to sun, rain, or salt mist won’t degrade the link between panels. Because these connectors have extremely low contact resistance, more of your panel’s electricity actually reaches the inverter.

And for safety, these connectors require a tool for disconnection and meet all UL/IEC standards, reducing fire risk. Ultimately, residential users get durable, high-efficiency PV connections that help their system run optimally with minimal maintenance.
