FAQ

Q: What is the difference between 1000V and 1500V DC battery cables?

A: 1000V DC cables are suitable for commercial and residential BESS systems. 1500V DC cables are required for utility-scale installations where higher string voltages reduce current and conductor sizes for the same power level.

Q: Can these cables be used for EV charging applications?

A: Yes, these battery cables meet similar requirements as EV charging cables and can be used for EV charging stations, particularly fast DC chargers with battery backup.

Q: What is the lead time for these cables?

A: Standard products are typically available from stock or within 2-3 weeks. Custom lengths or large project orders may require 4-6 weeks. Contact our sales team for specific requirements.

Q: Do you offer technical support for BESS cable selection?

A: Yes, our engineering team can help specify the right cables for your specific BESS application, including voltage drop calculations, current derating, and installation guidance.
