Enphase Energy (ENPH) shares surged approximately 8% on Thursday, breaking a four-day losing streak, after Barclays upgraded the solar technology company and pointed to its potential role in the rapidly expanding artificial intelligence data center market. The stock's rebound comes amid a volatile month, with shares down roughly 19% in June following a more than 100% gain in May. Despite the recent pullback, Enphase remains up over 60% year-to-date and has gained more than 80% over the past 12 months.
Barclays Upgrade Highlights AI Data Center Opportunity
Barclays analyst Christine Cho upgraded Enphase to Equal Weight from Underweight and raised the price target to $51 from $30, citing the company's development of solid-state transformers. Cho noted that solid-state transformers are expected to become a core component in AI data centers as hyperscalers adopt higher rack densities to support growing computing demands. The technology allows for more efficient conversion of electricity between different voltage levels, a critical need in power-hungry data centers.
Barclays estimates the total addressable market for solid-state transformers at approximately $2 billion and expects Enphase to increase its share over time. However, the firm does not anticipate a material financial contribution from this business until 2028, as the technology remains in the development stage. The upgrade reflects growing interest in solid-state transformers across the tech sector, with companies investing heavily in AI infrastructure.
New Commercial Microinverter Begins Shipping
Separately, Enphase announced the start of production shipments for its IQ9S-3P Commercial Microinverter in the United States. The new microinverter supports solar panels up to 770 watts and connects directly to three-phase 480Y/277-volt grid configurations without requiring external transformers. It utilizes gallium nitride technology, supports 18 amperes of continuous direct current, and delivers up to 548 volt-amperes of continuous output power.
The product meets UL 1741-SB and IEEE 1547-2018 grid compliance standards and includes features such as rapid shutdown, phase balancing, voltage and frequency ride-through, and loss-of-phase detection. Enphase said safe harbor orders for the IQ9S-3P Commercial Microinverter will remain open until July 4, 2026, allowing customers to secure equipment ahead of federal tax credit deadlines.
Domestic Manufacturing and Long-Term Growth
Enphase noted that units manufactured in the United States with domestic content may qualify as FEOC-compliant and could help eligible projects receive domestic content bonus tax credits, subject to project-specific requirements and applicable laws. The products also comply with Buy America Act standards for federal direct procurement contracts. The IQ9S-3P Commercial Microinverter connects to the company's IQ Gateway Commercial Pro system for real-time monitoring, energy management, and remote firmware updates. It carries a 25-year limited warranty, while the gateway comes with a 15-year limited warranty.
Based in Fremont, California, Enphase has shipped approximately 87.8 million microinverters globally and currently holds a market value of about $6.3 billion. The company's dual focus on AI data center opportunities and commercial solar innovation positions it for potential long-term growth, though near-term volatility remains a factor for investors.
