The Commercial PV Safety Landscape

NEC 2017 690.12 rapid shutdown requirements

Section 690.12 of the National Electric Code further advances previous rapid shutdown requirements. PV equipment manufacturers have approached this code requirement with various methods, however, most current solutions remain complicated and costly. In order to reduce costs, maintain a high level of safety and continue to grow the PV industry as a whole, simplification and standardization of rapid shutdown technology is critical.

The SunSpec Alliance

The SunSpec Alliance is a wellrespected trade group whose mission is to accelerate the growth of the distributed energy industry and expand the market for renewable power. More than 100 leading organizations are SunSpec Alliance participants and are investing in growing industry standardization. To date, the SunSpec Alliance has successfully introduced dozens of information and communication standards that have been adopted industry-wide.

The SunSpec Alliance recently introduced a method to achieve NEC 2017 module-level shutdown compliance through the use of power line communications (PLC). Titled the SunSpec Communication Signal for Rapid Shutdown Interoperability Specification, this open standard is designed to lower integration costs and deliver a variety of interoperable products to PV professionals. More than 30 companies actively contributed to the development of this particular standard, including SMA.

The SMA Safety Solution
Achieving compliance with NEC 2017 module-level rapid shutdown

The CORE1 PV inverter and the module-level shutdown devices combine to ensure PV systems comply with the latest 2017 NEC rapid shutdown requirements. The CORE1’s industry leading safety features have been further enhanced with support for the new SunSpec PLC signal for module-level rapid shutdown. Based on this industry standard, the Sunny Tripower CORE1 and SunSpec certified shutdown devices provide the most reliable, cost-effective solution to achieve compliance with 2017 NEC module-level rapid shutdown requirements in commercial rooftop systems.

SMA Sunny Tripower CORE1

When connected to the AC grid, the CORE1 inverter transmits the SunSpec PLC signal over the connected PV string conductors.

Sunny Tripower CORE1 50 kW

SunSpec Certified Shutdown Devices

The shutdown devices listen for the SunSpec PLC signal and reduce module output voltage to a safe level when the signal is not being received.

AC Disconnect

The main AC disconnect required for all PV systems serves as the rapid shutdown initiator. Emergency first responders need only open this disconnect to initiate rapid shutdown of the full PV system.

How does the solution work?

The CORE1 inverter transmits the SunSpec PLC “stay alive” signal over the connected PV string conductors—no additional communications wiring or devices are needed
The shutdown devices install quickly and easily without tools, and go into operation immediately without additional commissioning effort
Rapid shutdown is initiated when the PV system is disconnected from the AC grid by opening the main PV system disconnect—no additional initiation buttons, communication controllers or wiring are required
Initiating rapid shutdown de-energizes all controlled DC conductors outside and inside the array within 30 seconds in accordance with 2017 NEC 690.12
Once connection to the AC grid is restored, the PV system returns to normal operation without any additional actions required

Advanced AFCI Technology
Next-generation arc-fault protection for increased safety

Further addressing safety in commercial PV systems, SMA’s new line of Sunny Tripower CORE1 inverters also include advanced AFCI compliant to new Standard UL 1699B for arc fault protection.

SMA’s advanced AFCI technology offers a wealth of benefits including:

Uninterrupted operation with reduced nuisance tripping
Greater reliability in detection and interruption of PV array wiring faults
Identifying potential fire hazards and putting the PV array into a safe state before faults can escalate, which avoids extensive damage to the PV system and building
Intelligent detection algorithm that distinguishes actual arc-fault frequency patterns from other common signal noise on PV DC lines—including SunSpec PLC signal, on-site equipment, motor noise emissions and radio transmission noise
