How much difference could a 6% improvement in power conversion efficiency make? At a gigawatt-scale data center, it could free up enough power to supply a small city.
On the Climate Confident podcast, @KrapelsMarco, SVP at Enphase, joins host @TomRaftery to discuss how Enphase's solid-state transformer technology could help address growing AI data center power demands by reducing losses as electricity moves from the grid to computing infrastructure.
▶️ Listen to the full conversation: climateconfidentpodcast.com/…
As AI data centers drive growing demand for electricity, the industry is rethinking how power is converted and delivered.
Solid-state transformers (SSTs) could help data centers reduce energy losses and equipment footprint by using power electronics and semiconductors to deliver direct current (DC) power to computer racks with fewer conversion steps.
“For a gigawatt data center, if you are 5% more efficient, that’s $30 million in just the very energy cost itself that you can save.” – Enphase co-founder and CPO Raghu Belur.
Enphase successfully demonstrated the IQ Solid-State Transformer in October, and expects pilot deployments to begin in 2027.

A major milestone for Enphase manufacturing in the U.S. 🇺🇸
More than 8 million IQ Microinverters and nearly 500 MWh of IQ Batteries have now shipped from American facilities.
Since beginning U.S. microinverter shipments in 2023, Enphase has expanded domestic manufacturing to include IQ9N Microinverters for residential solar, IQ9N-3P and IQ9S-3P Commercial Microinverters, and the IQ Battery 10C.
For installers like @PlugPv, North State Solar Energy, and EMPWR Solar, domestic manufacturing means shorter lead times, a more reliable supply, and confidence in the quality of the products they install.
Enphase is also applying its established manufacturing capabilities to AI data center power infrastructure with the production of the IQ Solid-State Transformer (IQ SST) power modules in Texas.

What if powering more data centers started with the homes already connected to the grid?
On the latest episode of Climate Confident, @KrapelsMarco, SVP at Enphase, joins host @TomRaftery to discuss how solar and battery storage can help make better use of existing grid infrastructure as electricity demand grows.
Marco explores how equipping more homes with solar and batteries could help reduce their reliance on grid power, freeing up capacity for new demand while turning existing grid connections into thousands of flexible, dispatchable energy resources. This could help support data center development while reducing the need for additional behind-the-meter gas generation.

Bringing long-term energy savings to affordable housing.
At The Meadowmark Apartments in Castle Rock, Colorado, @NamasteSolar installed a 117.3 kW rooftop system to help reduce operating expenses while securing low-income and solar tax credits.
Powered by Enphase IQ8P-3P Microinverters, the system is expected to generate more than 157,000 kWh annually, offset nearly 39% of the building’s energy load, helping reduce electricity costs over time.
For Lead DC Installer Patrick Cavin, performance wasn’t the only advantage:
💬 “I appreciate how streamlined Enphase has made their QD cable and adapters. Easy to work with, and allows for complete foresight and control of branch circuit layout. The entire system’s proprietary nature makes for true plug-and-play installation.”

Enphase is bringing the IQ Solid-State Transformer (IQ SST) to RE+ in Las Vegas, November 17–19.
We'll showcase how its distributed architecture can support evolving power demands across AI data centers, utility-scale solar and battery storage, and DC fast-charging infrastructure for electric vehicles. By converting medium-voltage AC power directly to 800 VDC, the IQ SST uses modular power electronics designed to scale to multi-megawatt capacity.
Visit the Enphase team at booth N2026 in the North Hall at #REPlus to explore the IQ SST and more of our latest energy innovations.
A major milestone in the development of the Enphase solid-state transformer. ⚡
We have successfully demonstrated the IQ Solid-State Transformer (IQ SST) converting 13.8 kV AC to 800 VDC while maintaining stable output through rapid load changes that simulate the demands of AI compute racks.
Performed at its research and development lab in Austin, Texas, the test system consisted of 132 power modules, with 44 connected in series on each of three phases, operating together as a single system. The system maintained a stable 800 VDC output through load steps simulating the fast-changing demands of AI compute racks.
💬 “Over the past 20 years, we've built and shipped nearly 90 million microinverters, gaining extensive experience in designing and manufacturing reliable power electronics,” said Raghu Belur, co-founder and CPO at Enphase.
“IQ SST brings that same approach to AI data centers, moving us closer to delivering power more efficiently to AI compute racks.”
Next up: testing at 34.5 kV in the coming weeks, with megawatt-scale demonstrations expected before the end of 2026 and customer pilots planned for 2027.

Enphase and @Infineon have announced the world's first 900 V gallium nitride (GaN) bidirectional switch devices, designed for the Enphase IQ Solid-State Transformer (IQ SST) to advance power conversion for AI data centers.
Building on more than a decade of Enphase GaN research and Infineon’s device expertise, the technology enables high-frequency switching at higher voltages, helping reduce system losses, component count, size, and cost.
💬 "Enphase asks more of our technology than almost anyone, and medium-voltage solid-state transformers are exactly where high-voltage GaN proves its value," said Johannes Schoiswohl, senior vice president and head of GaN Systems Business Line at Infineon.
💬 "Moving to 900 V gives us more voltage headroom without giving up high-frequency switching, and it allows us to stay with components rated below 1 kV while reducing the number of converters in the system," said Hans van Antwerpen, senior vice president and chief technology officer at Enphase.
"Fewer parts in the power path means higher efficiency and fewer things that can fail."

Built to last. Powered by GaN.
Gallium nitride (GaN) enables more efficient power conversion, higher performance, and less heat than traditional silicon, making it one of the most important advances in modern power electronics.
That's why it's becoming a foundational technology across the Enphase platform, from next-generation microinverters to future storage, EV charging, and intelligent power infrastructure.
See how GaN is helping shape what's next:
When comparing solar and battery systems, it's worth asking who will stand behind your equipment years after installation.
Long-term support matters, from warranty coverage and replacement parts to software updates and system monitoring. Foreign Entity of Concern (FEOC) requirements add another consideration, with rules around manufacturer ownership and supply chain sourcing that can influence equipment choices in the U.S.
Understanding FEOC can help homeowners ask more informed questions when reviewing solar quotes and choosing a manufacturer they can count on.
