About the Episode:
It is estimated that by 2027 nearly half of all new solar installations will have energy storage attached, and today’s guest, Adam Knudsen of Dynapower, asserts that almost half of those will have DC coupled storage. The choice between AC or DC coupled systems has become a critical consideration for developers, utilities, and energy planners. While AC coupled systems have long dominated the market due to their established infrastructure and reliability, DC coupled technology is quickly gaining momentum. DC coupling reduces energy losses, simplifies system design, and requires less electrical infrastructure, so why has AC-coupled been so prevalent?
Adam Knudsen, CEO of Dynapower, breaks down how DC coupling is transforming modern energy storage systems. For over 60 years, Dynapower has led advancements in power electronics that address scalability and reliability issues. These innovations have enabled new applications, such as fast-charging for electric vehicles, supporting localized grids through microgrids, and integrating hydrogen production into renewable energy systems. Nico and Adam discuss when and why to use DC versus AC-coupled in clean energy applications.
Expect to learn:
Key differences between AC- and DC-coupled systems
Why DC coupling minimizes energy losses and simplifies system design
Why DC coupling is now scalable and viable for widespread adoption.
Why AC coupling has heretofore been the market leading approach.
What has changed to allow DC coupling to become more scalable
Tune in and learn how to decide which application might be right for your system.
NOTEWORTHY QUOTEs:
“When the economics continue to result in a positive benefit on the overall deployment of the project, not just the CAPEX, but also on the efficiency side, then that’s going to be well received.”
“The total amount of electrical infrastructure required for AC coupled storage is significantly greater than the DC coupled storage. DC to DC technology is ready for prime time. It’s being deployed in gigawatts around the world and we’re a proud innovative partner in that part of the process.”
