APsmart Exhibited at SNEC 15th Conference & Exhibition and held on-site certification ceremony for RSD-D

/in , /by

Following a very special period for everyone, the whole APsmart team is delighted and excited more than ever to present our future-facing advanced rapid shutdown solutions RSD-D products to you at the SNEC Conference & Exhibition in Shanghai, China.

The APsystems booth hosted an on-site certification ceremony for the new generation of dual Rapid shutdown products: the RSD-D. CSA Group leaders visited the APsystems booth and presented relevant product certificates in person to Guoliang Wu, Vice General Manager of Engineering at APsystems.

The new RSD-D meets NEC 2017 & 2020 (690.12) requirements, enabling the critical rapid shutdown function while simultaneously improving product cost and performance. By using the RSD-D and Transmitter-PLC in solar PV installations, the connection between each module can be cut off  in case of an emergency, thus eliminating any high voltage DC in the solar array, which reduces the risk of accidents and improves the safety of the PV system.

The highlights of RSD-D include:

  • Dual-input channel
  • Supports modules at 8-80V Per Channel
  • Maximum Current is 15A/20Aper input
  • Buckle to the PV module frame directly
  • IP68 enclosure rating
  • Meets NEC 2017 & 2020 (690.12) requirements
  • Executes rapid shutdown of system when Transmitter-PLC signal is absent
  • Meets SunSpec requirements

Every afternoon during the conference, APsmart technical experts shared best installation practices, system introduction and case study analysis on the latest rapid shutdown products and solutions, which attracted a large audience.

FIMER partners with APsystems for rapid shutdown certifications

/in , /by

FIMER, one of the world’s largest manufacturers of solar inverters, has announced its UNO-DM-PLUS-Q-US and PVS-60-TL-US string inverters for residential and C&I applications in the US are now fully compatible with the APsmart Photovoltaic Rapid Shutdown Equipment (PVRSE) from APsystems.

The APsmart system by APsystems allows constant monitoring and communication between the RSD-S-PLC and Transmitter-PLC, which means that FIMER’s inverters now meet the mandatory rapid shutdown regulatory requirements for grid connection in the US.

With the Solar Energy Industries Association (SEIA) reporting that the US installed 3.8GW of solar PV capacity in Q3 2020, and that residential installations increased by 14 percent between Q2 to Q3, the US solar PV market is expected to continue its recovery from the COVID-19 pandemic with growth during 2021 and beyond.

The partnership means FIMER’s inverters can now be coupled with a cost-effective, safe, and reliable rapid shutdown solution which is UL 1741 certified and fully compliant with the National Electric Code (NEC) 2014, 2017 and 2020 690.12 Rapid Shutdown Requirements.

FIMER VP Technology for the US Ananda Hartzell said: “As a provider of a comprehensive, innovative portfolio of solar inverter products, systems and services addressing all market segments and types of solar installations, FIMER is well-positioned to support the demand in the US’ residential, commercial and industrial solar sectors. Working with APsystems means we now have one of the most widely recognised and respected solutions on the market, as its RSD system is already installed in approximately 300,000 around the globe and comes with 25 years’ warranty.”

The APsmart RSD System is a SunSpec Alliance-certified device which allows constant monitoring and communication between the RSD-S-PLC and Transmitter-PLC. FIMER’s string inverters, combined with APsmart’s RSD devices, offer a solution which provides all the required safety features to shut down a PV array at the module-level, which is the safest way to de-energize a PV system.

Olivier Jacques, APsystems business unit president and global executive vice president, further added: “FIMER is one of the largest manufacturers of solar inverters in the world, and its product portfolio complemented our rapid shutdown system solutions, meaning that end customers can be confident that FIMER’s inverters meet the rapid shutdown requirements in the US.”

The products are available through both FIMER and APsystems’ APsmart distribution partner networks.
