AI data centers have outgrown legacy power architecture. Built on 20 years of innovation, Enphase is bringing its proven platform that has powered 87.5 million microinverters in the field to the data center era. The IQ Solid-State Transformer (IQ SST) was purpose-built for AI-scale workloads, delivering scalable megawatt-class power directly to the rack with ultra-fast response and high availability. Instead of legacy bulk conversion, IQ SST uses a distributed architecture built from hundreds of power modules in a delta configuration, enabling efficient conversion across multiple utility interconnection classes. Enphase custom ASIC (Kestrel) and bidirectional GaN technology together will form its core, enabling single-stage power conversion, high-frequency operation, and industry-leading efficiency. No internal batteries. Fewer failure points. Built for long-term reliability at scale: enphase.com/iq-solid-state…

U.S.-MANUFACTURED SOLID-STATE TRANSFORMER China produces some 60 percent of the world's power transformers. The US imports $4 billion annually. Last week, @POTUS invoked the Defense Production Act and directed @ENERGY to expand domestic transformer manufacturing. President Trump called America's capacity to produce that equipment "dangerously limited." He's right. Conventional iron and copper transformers are built for a one-way grid. They enable cascading failures. And they cannot properly contend with the dynamism of AI datacenters, which are quite likely to dominate new load additions for some time. The reason the grid – and the economy – is at an impasse is not that we cannot generate enough energy. It's that we cannot move it cost-effectively. This week @Enphase revealed a breakthrough for the world — the IQ Solid-State Transformer. Starting with AI data centers, the IQ Solid-State Transformer takes 34.5kV from the grid and delivers 800V DC directly to AI compute racks — collapsing a legacy five-stage power chain into one conversion. The sidecar battery rack bolted alongside every compute rack today — the PSU, BBU, CBU — can be reduced or eliminated entirely. Less power infrastructure. More space for GPUs. More tokens. More revenue. For data center operators and AI companies, IQ SST's benefits drop straight to EPS. The numbers on the Enphase IQ SST: ⚡ 98.5% efficiency ⏱️ Intrinsic sub-millisecond response — no battery buffer required 🔁 >250 kHz switching — custom Kestrel 22nm ASIC + bidirectional GaN 🔩 342 modules per unit, built-in redundancy, no single point of failure ✅ Five-nines availability — hot-swap without shutdown 🇺🇸 US manufacturing — Arlington TX + Columbia SC, high-volume manufacturing 🔬 ~90M inverter units deployed across 165 countries — nine generations of this architecture already in the field and shipping electrons But what is most important is this: the U.S. needs to be able to rapidly increase its power density. Not just at data centers, but everywhere on the grid. Passives on the grid generate heat, threaten cascading failures, and are not variable. Production capacity is mostly in adversarial nations. And legacy SST designs, borrowed from academic papers, cannot respond at sub-millisecond speeds. IQ SST can. The reason why is Kestrel — a 5th-generation custom 22nm ASIC developed across nine generations of silicon, paired with bidirectional GaN switches already proven in Enphase's IQ9 (already produced in the many-millions). Single-stage power conversion. Sub-millisecond response. Semiconductor-based and software-defined. The core of what we do @HNVRcap, from my first job in Silicon Valley working on low-power analog/digital microcontrollers, to our investments across infra, sim, apps, and power is about the convergence of power and computing. IQ SST is the foundation for achieving a grid that scales the way silicon scales, not the way steel does. And is driven by custom processors that have done billions upon billions of hours in the field. This is a semiconductor company's answer to a problem we've treated as mechanical for a hundred years. The grid's missing link – the Enphase IQ SST.

Introducing the Enphase IQ Solid-State Transformer (IQ SST): a distributed solid‑state transformer platform purpose-built for AI data centers. As AI workloads scale toward megawatt-level densities, the IQ SST eliminates the need for traditional UPS systems and battery sidecars, reducing electrical infrastructure and freeing up more space for compute. In an industry where power density and floor space are increasingly constrained, returning space to compute infrastructure can be a meaningful economic advantage. Designed to replace traditional centralized power conversion with a distributed “supercluster” architecture, this next-gen solid-state transformer platform is rated at 1.25 MW and delivers 98.5% efficiency and 99.999% system availability. 💬 “AI is changing how power must be delivered to compute infrastructure,” said Badri Kothandaraman, president and CEO of Enphase. “For two decades, Enphase has built distributed, semiconductor- and software-defined power conversion systems at scale. As AI racks move toward 800 VDC (±400 VDC) architectures and megawatt-scale densities, we believe that distributed architecture is well suited to this transition, and it is what we are building.” See how IQ SST is shaping the next generation of AI power infrastructure: investor.enphase.com/news-releases/…
