Fronius USA has released the Fronius Rapid Shutdown Box for an immediate, compliant and convenient solution to the latest NEC 2014 code requirement of Rapid Shutdown.

The NEC of 2014 requires photovoltaic systems to have an AC functionality to manually shutdown the power in the event of an emergency. This new code requirement has raised concerns throughout the solar industry since many products are not able to accomodate such functionailty. The Fronius Rapid Shutdown Box is a convenient solution for system owners and developers to implement the safety needs required by this new requirement.

With the Fronius Rapid Shutdown Box, Fronius is able to offer a reliable and easy way to install a solution for all single phase Fronius SnapINverters from 1.5 kW to 8.2 kW. Directly connected to the inverter through the same DC conduit as the DC homeruns, the Fronius solution minimizes the number of boxes needed providing an ease of installation. No extra power supply or ground level hardware needed, reducing system cost. The Rapid Shutdown is triggered whenever AC is not present, and the DC lines are rapidly discharged by the inverter. Fronius is accepting orders now.
