FAQ

Q: What is the difference between PV1-F and H1Z2Z2-K solar cables?

A: Both cables meet similar performance requirements but belong to different standard systems. PV1-F follows the VDE specification, while H1Z2Z2-K is the harmonized European standard (HAR). Both are acceptable for solar installations and are often used interchangeably.

Q: Can these cables be used in both AC and DC applications?

A: These cables are primarily designed for DC solar applications (up to 1000V or 1500V DC). They can also be used for AC applications up to their AC voltage rating, making them suitable for inverter output connections.

Q: What is the maximum string length I can use with these cables?

A: Maximum string length depends on system voltage, current, and allowable voltage drop. Our technical team can perform voltage drop calculations for your specific system parameters.

Q: Do you offer documentation for building permits?

A: Yes, we provide complete technical documentation including TUV certificates, datasheets, test reports, and installation guidelines. Contact our technical team for project-specific documentation packages.
