Come and see APsystems and APsmart Solutions at ASEAN Sustainable Energy Week 2022

ASEAN Sustainable Energy Week, ASEAN’s most comprehensive international exhibition and conference, comes to Thailand on 14-16, September, and APsystems and APsmart solutions will be there in force.

Join us at our booth H27, where we’ll have a joint booth with our partner-Sunday Solar, bringing you a full range of advanced MLPE and ESS products, including microinverters, rapid shutdown devices and storage solutions.

Come and to see the most powerful dual-module microinverter DS3 series s and our 2nd generation of native 3-phase QUAD microinverter offering unprecedented power output, the QT2. Both units utilize a 2.4GHz wireless Zigbee mesh network, providing enhanced data transmissions speeds up to three times faster than conventional powerline communication (PLC).

DC MLPE devices will also be displayed, including the dual module Rapid Shutdown Device (RSD-D) and Transmitter-PLC. Compliant with NEC 690.12 Rapid Shutdown and SunSpec certified, the RSD-D and Transmitter-PLC is an ideal solution for module-level rapid shutdown.

Also discover our new energy storage products on display for the first time on an exhibition. With the AC coupling technology, APsystems energy storage system is applicable to both existing and new solar installations. Easy to install and meeting the major application demands, APstorage will help users to optimize their utility bills, offering full flexibility to manage their electrical consumption. With integrated backup functions, APstorage can also supply power to the household in case of power grid cuts.

Join APsmart at RE+ International 2022

APsmart invites you to stop by booth #2838 at this year’s RE+ International trade show in Anaheim, California to see its advanced solar Rapid Shutdown products, including the widely popular RSD products: the RSD-D and Transmitter-PLC with millions of units sold!

RSD-D is capable of serving two PV modules simultaneously, is quick and easy to install, and is highly cost-effective. Also, it meets NEC 2017 & 2020 (690.12) requirements, enabling the critical rapid shutdown function while simultaneously improving product cost and performance. Utilizing the RSD-D and Transmitter-PLC in solar PV installations also enables the connection between each module to be severed both remotely and manually in case of an emergency, thereby de-energizing the array and eliminating any high voltage DC hazard, which reduces the risk of accidents and improves the safety of the PV system.

Stop by booth #2838 to see this amazing APsmart product offering. We look forward to seeing you there!

Happy Holidays 2021

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

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.

Upcoming Webinar: APsmart Commercial Rapid Shutdown Solution

Join APsmart for this informative webinar on its Rapid Shutdown Device (RSD) & Transmitter solution. The webinar will take place on two dates:

Wednesday, May 27th at 9:00 am PT / 12:00 pm ET
Wednesday, June 3rd at 9:00 am PT / 12:00 pm ET

APsmart Webinar: Rapid Shutdown Solution Overview and Installation Training

Description: This webinar will cover the features and benefits of the Rapid Shutdown Device (RSD) and Transmitter comprising APsmart’s convenient rapid shutdown system for commercial projects. Attendees will learn:

  • An overview of the APsmart Rapid Shutdown solution
  • Details about the system technology and capability
  • Benefits and options of using the APsmart RSD and Transmitter solution
  • Installation and operation of the RSD and Transmitter

The APsmart RSD System is a SunSpec Alliance Certified (paired) device which maintains constant communication between the RSD-S-PLC and Transmitter-PLC, constantly monitoring voltage and current. When proper voltage is not detected, the Transmitter-PLC stops sending the keep-alive signal to the RSD-S-PLC device, initiating a module-level rapid shutdown sequence.

From the developers at APsystems, APsmart offers state-of-the-art PV module rapid shutdown devices (RSD-S-PLC), ideal for any new or existing string or central inverter system, and meeting U.S. NEC 2017 690.12 Rapid Shutdown requirements. Leveraging APsystems’ proven expertise in module-level power electronics, APsmart solutions are powered by ASIC with internal IP and integrated with TI chips at the system-level application.
