The box is directly connected to the inverter through the same conduit as the DC homeruns and powered by the array, the Fronius solution minimizes the number of components and eliminates the need for an external power supply. It's low-profile design allows for installation underneath the modules, insuring a clean system look and thanks to the NEMA 4X rating, the box is built for severe outdoor conditions. MC4 connectors, spring loaded terminals and generous wiring space make wiring their new generation Rapid Shutdown Box even easier.
