Fronius Symo Advanced inverters, typically used in commercial settings, are now UL 3741 certified in conjunction 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 certification confirms that a solar system using a combination of approved inverters and mounting systems complies with rapid shutdown rules without needing module-level shutdown devices.
Fronius Symo Advanced inverters are approved to comply with NEC 690.12 with the following mounting systems:
- clawFR 5° (PanelClaw)
- clawFR 10° (PanelClaw)
- Dual tilt flat roof (PanelClaw)
- BX Ballast System (IronRidge)
The Symo Advanced string inverter is UL 3741 certified for use with the PanelClaw and IronRidge racking systems when the inverter is installed within the 1-ft array boundary.
