NEC 2014 Arc Fault & Rapid Shutdown
NEC 2014 690.11 and 690.12
NEC 2011 690.11 mandated Arc Fault protection on
PV systems that are On top or Penetrate a building
Examples: If the PV modules are on the ground, but the inverter is located in a building.
NEC 2014 690.11 mandates Arc Fault protection EVERYWHERE
NEC 2014 690.12 mandates rapid shut on PV systems “On or inside a Building”
As of 1/1/15, 22 states have adopted NEC 2014; 16 are utilizing NEC 2011; 8 are still on NEC 2008; and 3 have no code adoption at all - to see a complete listing, CLICK HERE.
Are Solectria Products compliant with the arc fault and rapid shutdown requirements?
Absolutely - below is a list of our products and how they are compliant with this code:

- Rapid shutdown, optional, met when:
- Placed within close proximity to the array;
- If not within close proximity, must be coupled with our rapid shutdown combiner box (available April 2015)
- PVI 14-36TL (Three-Phase String Inverters)
- Arc fault: standard, integrated
- Rapid Shutdown, meets rapid shutdown requirement when:
- installed within 10 feet of array;
- if not installed within 10 feet of array, 3rd party solution required
- PVI 50-100KW (Three-Phase Central Inverter)
- Arc fault: optional with ARCCOM combiner
- Rapid shutdown: optional, must order rapid shutdown inverter option and ARCCOM combiner
