In Part I of this blog post series, we summarized a few of the benefits in becoming an SMA PowerUP ...
Next-generation commercial PV systems are much more than a way to offset energy costs. They are true energy solutions, revolutionizing the way businesses participate in energy markets. From generation to load usage, commercial solutions from SMA allow plant owners an unmatched level of monitoring and control including the ability to participate in the energy trading market of the future, opening untapped revenue streams.
The Sunny Tripower series: optimized for commercial PV applications
The Sunny Tripower is a field-proven commercial PV inverter with more than 15 GW installed worldwide. With new power classes, new functionality and options for repowering, the Sunny Tripower CORE1 is SMA’s latest addition to a successful portfolio of established commercial solutions.
Advanced technology for maximum safety
SunSpec compatible inverter technology in conjunction with SMA’s TS4-F device gives integrators a cost-effective way to achieve compliance with the NEC 2017 module-level shutdown requirements. Further addressing safety in commercial PV systems, SMA inverters also include advanced AFCI compliant to new Standard UL 1699B for arc fault protection.
TS4-F The latest addition to SMA’s TS4 platform with a focus on emergency responder safety. It uses proven MLPE technology from SMA to provide rapid shutdown only, creating a reliable, economical product that focuses on key functions to enable NEC compliance.
Superior communication and control
In combination with Sunny Portal powered by ennexOS, an Internet-of-things (IoT) platform that manages all energy generation sources and data on a single platform, the Data Manager M is the ideal solution for commercial system owners and operators. It optimizes communication, monitoring and control of decentralized PV systems for up to 50 devices.
Proactive service strategy
In addition to leading O&M services and the industry’s number one service team, SMA has brought proven technology from the residential market to our new commercial solutions. SMA Smart Connected is a proactive O&M solution that saves integrators time and money while maximizing system owners’ ROI. In fact, this technology can cut truck rolls in half and save system owners up to $6 million in service costs across the lifetime of a 100 MW portfolio.
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 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 CORE1 PV inverter and the TS4-R-F module-level 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 SMA’s new TS4-R-F device provide the most reliable, cost-effective solution to achieve compliance with 2017 NEC module-level rapid shutdown requirements in commercial rooftop systems.
When connected to the AC grid, the CORE1 inverter transmits the SunSpec PLC signal over the connected PV string conductors.
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.
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:
The world's first freestanding string inverter for decentralized rooftop and ground-based PV systems. The unique design and innovative installation method of this 50 kW inverter reduces installation time by 60%.
With a multi-string design and the latest grid management functions, this string inverter is as equally suited to the agricultural industry as it is for factories. Installers all over the world depend on this tried-and-tested inverter platform for maximum flexibility and low system costs.
With the online portal for central monitoring, PV system operators do not only save time and money but also always have access to essential data.
With more than 50 GW of installed power and services in 20 markets worldwide, SMA O & M services offer advanced PV inverter and PV system expertise.
