Arc Fault Detection System
To address the risk of PV systems starting fires — required by the new 2011 National Electric Code — SolarBos unveiled the Arc Fault Detection and Interruption (AFDI) combiner box and the Ground Fault Interruption (GFI) solution.
The AFDI combiner contains a module that detects series arcs and automatically disconnects the ungrounded conductor from the rest of the system, breaking the circuit, which stops the arc and prevents a fire from starting.
The combiner is designed for reliability and cost-effectiveness, and can also be configured to work with a GFI device or system to open the ungrounded output of the combiner box when a ground fault is detected.
