SolarBOS says it’s offering the industry’s first working arc-fault and ground-fault detection and interruption combiner box, as well as a ground fault interruption for PV systems. The AFDI combiner allows system integrators to meet the letter of the 2011 National Electric Code in a cost-effective and reliable manner. The combiner box has a module that detects series arcs and automatically disconnects the ungrounded conductor from the rest of the system, breaking the circuit and stopping the arc, which prevents fires from starting. It can also be configured to work with a Ground Fault Interruption (GFI) device or system to open the ungrounded output of the combiner box when a ground fault is detected. The company says without AFDI or GFI capability at the combiner box, there is no way to automatically shut off the output from a PV array in the case of an arc fault or ground fault in the array wiring. The AFDI combiner not only solves this problem and meets the new NEC requirements in a cost-effective way.
