Why Choose Staubli MC4?
✔
1. Established Heritage & Technology Benchmark: The Stäubli Group was established in 1892, and the MULTILAM technology used became an industry benchmark.
✔
2. Efficient connection creates more benefits.
Case: 1MW photovoltaic power station
In the first year of operation of the power station, the Stäubli MC4 can generate 1175kWh (with less loss) of electricity for the owner, which is equivalent to a 0.78% increase in system efficiency; a typical 50MW power station, within 25 years of operation, the Stäubli MC4 can provide the owner's more power (less loss) of electricity is about 1.46 million kWh.
✔
3. Safe and reliable: Successfully connected to 150GW Solar Plants worldwide. Rainproof, moisture-proof, dust-proof and durable, waterproof grade IP68.

Choosing High-quality PV Connectors is Essential
1. Fire Risk Correlation: The well-known foreign organization Fraunhofer ISE and TÜV jointly investigated the cause of the photovoltaic system fire and found that the first and third fire causes are all related to the connector.
2. Financial Impact: In July 2016, the report released by the European Union Horizon 2020 "Solar bankability" project team showed that among the top 20 risks of power stations, the amount of electricity generated by the damage or burning of the connector Loss of revenue ranks second.
3. Long-term Cost: Low-quality rather than high-quality connectors will lead to increased costs.
Therefore, Choosing a High-quality PV Connector is Very Important

MC4 Test Socket and Plug
The test rod is used to check whether the MC4 and MC4-Evo 2 contacts are in place in the contact body. Point the test rod to the correct position and insert the male/female connector. The white mark must be visible if the contact is tested.
Frequently Asked Questions (FAQ)
What makes Staubli MC4 connectors more efficient than others?
Staubli MC4 connectors feature proprietary MULTILAM technology, which guarantees a long-term, extremely low contact resistance (≤0.25mΩ). This helps minimize electricity losses and increases overall power generation for solar plants.
Are Staubli MC4 connectors suitable for wet and dusty environments?
Yes, Staubli MC4 connectors carry an IP68 protection rating, making them highly durable, rainproof, dustproof, and moisture-resistant for reliable outdoor operation.
How does using high-quality connectors prevent fire risks in PV systems?
Research by organizations like Fraunhofer ISE and TÜV shows that connector failure is a primary cause of fires in solar installations. Staubli's robust build quality, stable resistance, and IP68 protection dramatically lower the risk of electrical faults and overheating.
Have these connectors passed tests for agricultural or coastal applications?
Yes, Staubli MC4 connectors have successfully passed both the Ammonia Resistance Test and the Salt Spray Test. This validates their reliability for coastal solar plants and complementary agricultural or fishery PV projects.
What cable cross-sections are compatible with Staubli MC4 connectors?
They support single-core cables with cross-sections of 2.5 mm², 4 mm², 6 mm², and 10 mm².
