Fronius Symo Advanced inverters now rapid-shutdown-compliant with PanelClaw, IronRidge mounting
- Fronius Symo Advanced inverters, generally used in commercial setups, are currently UL 3741 licensed along with PanelClaw and IronRidge mounting systems.
UL 3741 is a solution to the NEC 690.12 requirement of module level rapid shutdown within a solar system. The UL qualification verifies that a solar system making use of a combination of approved inverters as well as mounting systems follow rapid shutdown rules without needing module-level shutdown gadgets.
Fronius Symo Advanced inverters are accepted to abide by NEC 690.12 with the following mounting systems:
- clawFR 5 ° (PanelClaw).
- clawFR 10 ° (PanelClaw).
- Dual tilt flat roof covering (PanelClaw).
- BX Ballast System (IronRidge).
The Symo Advanced string inverter is UL 3741 licensed for use with the PanelClaw as well as IronRidge racking systems when the inverter is installed within the 1-ft array boundary.
