Common Questions
What makes these connectors "tool-free" and "crimp-free"?
The MC4-Evo Ready connectors utilise an automatic spring clamp mechanism. You simply insert the stripped PV cable, and the clamp secures the conductor, eliminating the need for a separate crimping tool or process.
Are these compatible with my existing MC4 connectors?
Yes, the Stäubli MC4-Evo Ready connectors are fully mateable with the entire Stäubli Original MC4 product portfolio. This compatibility has been verified by TÜV Rheinland interoperability testing.
What cable sizes can I use with these connectors?
These connectors are designed for 4 mm² and 6 mm² single-core photovoltaic cables. The outer diameter of the cable should be between 5.4 mm and 7.6 mm for proper fitment and sealing.
What are the maximum voltage and current ratings?
The Stäubli MC4-Evo Ready connectors are rated for a maximum system voltage of 1500 V DC and a maximum current of 30 A.
Installation Notes
- Installation and commissioning should only be carried out by a qualified electrician or electrically instructed person.
- Ensure the system is de-energised before performing any installation or maintenance work.
- Use only tinned copper conductors; bare, oxidised, or PVC-insulated cables are not permitted by Stäubli for safety reasons.
- Strip the cable insulation to the recommended length (typically 15-16.5 mm) as per manufacturer instructions.
- Ensure the connector is correctly screwed together to guarantee the specified IP protection class when mated.
- Protect unmated connectors from contamination using Stäubli sealing caps.
Before You Buy
- Verify your solar cable's cross-section (4 mm² or 6 mm²) and outer diameter (5.4–7.6 mm) for compatibility.
- Confirm the voltage and current requirements of your PV system to ensure these connectors are suitable.
- Ensure compatibility with any existing MC4 components in your installation.
- Consult the official Stäubli datasheet and assembly instructions for detailed guidance.
Always verify product specifications and compatibility with your system components before purchase and installation. All technical data is based on manufacturer specifications.
