Enphase Energy Inc. is pivoting to power artificial intelligence data centers, unveiling a new hardware roadmap that challenges the industry’s traditional power infrastructure and targets significant efficiency gains. The move expands the solar microinverter company’s addressable market beyond its residential and commercial roots, contributing to a 32% rally in its stock over the past week.
“Data centers face growing power demand, fast load swings and too many conversion stages between the grid and compute infrastructure,” President and Chief Executive Officer Badri Kothandaraman said during a company business update, outlining the strategy. He described Enphase’s core differentiation as semiconductor integration and software-defined products.
The company’s new IQ Solid-State Transformer (IQ SST) is designed as a 1.25-megawatt building block that converts medium-voltage AC into 800-volt DC for AI racks, a critical requirement for modern GPUs like those from Nvidia. Built on Gallium Nitride (GaN) technology and a custom Kestrel ASIC, the system is designed for 98.5% peak efficiency and 99.999% availability. Enphase plans for internal demonstrations in 2026, customer pilots in 2027, and volume shipments in 2028.
This strategic shift into the high-growth data center market could unlock significant new revenue for Enphase, whose market capitalization is now approaching $6.89 billion. While some analysts remain cautious—with Barclays maintaining an Underweight rating—the stock has surged 50% year-to-date, reaching a 52-week high of $52.95 as investors begin to price in the long-term opportunity.
Alongside its data center ambitions, Enphase continues to advance its core product lines. The company has started shipping its GaN-based IQ9S-3P commercial microinverters and announced pre-orders for a 480-volt model designed for higher-wattage U.S.-made solar panels. These rollouts are bolstered by a recent $52 million safe harbor deal with a U.S. financing firm for IQ9 microinverters.
In its residential segment, Enphase is developing a fifth-generation battery that will use 100 amp-hour prismatic cells, allowing a 30 kilowatt-hour stack to be housed in a single wall-mounted box. The company also plans to launch a bidirectional EV charger capable of vehicle-to-home backup, with pre-orders expected in the third quarter.
Kothandaraman acknowledged a competitive landscape, particularly from Chinese manufacturers in Europe. To adapt, Enphase has strategically reduced prices on its microinverters and batteries in both the U.S. and Europe over the last two quarters while maintaining gross margins in the mid-40% range.
For the second quarter, Enphase projected revenue between $280 million and $310 million. Despite the aggressive product roadmap and recent stock rally, the company’s trailing one-year return remains negative at -3.45%, indicating the recovery is still nascent.
