Product Information
Full details
This Lapp ÖLFLEX® SOLAR XLS-R T cable is designed for solar photovoltaic (PV) installations, connecting solar panels to inverters or charge controllers. It offers a thin, light, and robust design with electron beam cross-linking for durability. A key benefit is its high voltage rating, ensuring safe and efficient power transmission. However, this specific product is a 50-meter length, which may require planning for larger or smaller projects.

FAQs
What is electron beam cross-linking?
Electron beam cross-linking is a process that uses high-energy electrons to create chemical bonds within the polymer structure of the cable material. This significantly enhances its resistance to heat, chemicals, UV radiation, and mechanical stress, making it more durable.
Is this cable suitable for AC power?
No, this cable, designated as ÖLFLEX® SOLAR XLS-R T, is specifically designed for DC (Direct Current) circuits in solar photovoltaic (PV) systems. It is not intended for AC power applications.
What is the meaning of 6 mm²?
6 mm² refers to the cross-sectional area of the conductor inside the cable. This measurement indicates the cable's capacity to carry electrical current safely and efficiently.
Can I use this cable for longer runs?
While the cable is designed for efficient power transmission, very long runs can lead to voltage drop. It is important to calculate the expected voltage drop based on the cable length, current, and conductor size (6 mm²) to ensure it stays within acceptable limits for your system.
What are the primary environmental resistances of this cable?
This cable offers excellent resistance to UV radiation, ozone, high temperatures, and various weather conditions, making it suitable for outdoor solar installations.
How do I determine if this 50-meter length is sufficient?
Measure the total distance required for your cable runs between panels and the inverter. Compare this to the 50-meter length provided. It's advisable to add a small buffer for slack and routing. If the required length exceeds 50 meters, you may need multiple lengths or a longer option if available.
Troubleshooting
Cable overheating
Check for proper conductor sizing for the current load. Ensure connections are tight and free from corrosion. Verify the cable is not exceeding its maximum rated temperature or voltage.
No power output from solar array
Verify all connections are secure and correctly polarized. Check for any physical damage to the cable. Test continuity of the cable using a multimeter.
Difficulty stripping cable insulation
Use a cable stripper specifically designed for solar cables or PV wire. Ensure the stripper blade is sharp and set to the correct depth to avoid damaging the conductors.
Pros and Cons
Pros
- High voltage rating suitable for solar applications
- Durable and robust design for longevity
- Thin and light for easier installation

Setup, Compatibility & Care
Setup:
- Ensure the solar panels and inverter are powered off and disconnected from any power source before installation.
- Use appropriate tools for stripping the cable jacket and insulation to expose the conductors.
- Connect the conductors securely to the designated terminals on the solar panels and the inverter or charge controller, ensuring correct polarity (+/-).
- Route the cable neatly, avoiding sharp bends or kinks, and secure it using UV-resistant cable ties or clips suitable for outdoor use.
Compatibility:
- This cable is specifically designed for use with DC (Direct Current) circuits in solar photovoltaic (PV) systems.
- It is compatible with standard solar panel junction boxes and inverters/charge controllers that accept 6 mm² solar cable.
- Always verify the voltage and current ratings of your solar array components to ensure they match the cable's specifications.
Care:
- Regularly inspect the cable for any signs of damage, such as cuts, abrasions, or degradation of the outer jacket.
- Keep the cable clean by wiping it with a damp cloth if necessary; avoid using harsh chemicals or solvents.
- Ensure connections remain tight and free from corrosion.
- Protect the cable from physical damage by sharp objects or excessive strain.
