SolarBOS Unveils First Arc Fault Detection & Interruption Combiner Box and True GFI Solution for PV Systems

October 02, 2011 by Jeff Shepard

SolarBOS, Inc. has unveiled what it says is the industry’s first Arc Fault Detection and Interruption (AFDI) combiner box as well as the first true Ground Fault Interruption (GFI) solution for photovoltaic (PV) systems.

According to the company, the new AFDI combiner allows system integrators to meet the letter of 2011 NEC in a cost effective and reliable manner. The SolarBOS’ AFDI combiner box has 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 SolarBOS AFDI combiner 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.

"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," said Jason Schripsema, CEO of SolarBOS. "Our new AFDI combiner not only solves this problem and meets the new NEC requirements, it does so in a cost effective way."
