How to Comply w/NEC 2017 690.11 Arc-Fault Circuit Proection (DC)-Strings > 3 Modules?
Is there any DC Arc-Fault protection equipment currently available that can satisfy the requirements of NEC 2017 690.11 for PV source and output circuits with over three 60 cell PV modules in series?
If "no" how do we get this by the AHJ code inspector or is there "equivalent protection?"
2017 NEC 690.11 states:
Thanks!

2017 NEC 690.11 states:
PV systems operating at 80V dc or greater between any two conductors must be protected by a listed PV arc-fault circuit interrupter or other component listed to provide equivalent protection.
