Fronius 4202014479 Bus Bar for Symo Inverter

Fronius Bus Bar For Symo Inverters

The Fronius Bus Bar for Symo Inverters is an insulated copper comb bus bar designed to bridge multiple DC inputs on Fronius Symo series inverters. It allows installers to combine incoming solar strings directly inside the inverter wiring box to streamline cabling and reduce overall labor. The plastic-encased comb design prevents accidental contact during maintenance while maintaining clean wire routing inside the cabinet.

Built to accept both copper and aluminum wiring from #10 to #2 AWG, this bus bar provides a solid electrical connection for commercial solar arrays. Screw terminals require 50 lb-in of tightening torque to secure conductors and ensure steady electrical flow under load. This accessory is a direct replacement part manufactured by Fronius to meet UL 508 and CSA safety standards.
