Fronius Rapid Shutdown Box

With the Fronius Rapid Shutdown Box, Fronius offers a reliable and easy to install solutions for all SnapINverters (up to 600 V input). Connected to the inverter through a closed control circuit, the Rapid Shutdown Box provides a safe means of de-energizing the DC circuit from the array to the inverter. If the inverter is disconnected from the grid, the control circuit is opened, and the output from the Rapid Shutdown Box is limited to less than 30 VDC within 10 seconds as mandated by CEC 2015 64-218. Fronius’ solution minimizes costs by requiring only a control circuit; no extra power supply, ground level hardware, or modification to the inverter is required.
