Key Points

  • Enphase Energy shares rose 14% on Thursday and gained 26% over the week as investor interest centered on the company’s solid-state transformer development.
  • Goldman Sachs highlighted the potential for power conversion technology in AI data centers as architectures move toward 800V DC, and estimated a roughly 10 GW total addressable market for solid-state transformers by 2030.
  • Goldman Sachs maintained a Buy rating on Enphase, raised its 12-month price target to $57 from $51, and projects Enphase 2030 revenue between $110M and $910M with earnings of $0.21 to $1.75 per share under its scenarios.

Enphase Energy Inc (NASDAQ:ENPH) saw its share price rise 14% on Thursday and finish the week up 26% as market participants repositioned around the firm's push into power conversion hardware for modern data centers. The company has publicly disclosed work on a solid-state transformer product.

In a client note, Goldman Sachs analyst Brian Lee examined the role of solid-state transformers and assessed Enphase Energy's strategic placement. The note states that as modern data centers are expected to evolve toward an 800V DC architecture per the Nvidia roadmap in coming years, a clearer window is opening for power conversion technologies across the AI data center footprint. Goldman Sachs observed that multiple technology vendors plan to introduce advanced transformer solutions to meet the tightening demands for efficiency, reliability, and higher power capacity in future AI-focused facilities.

Enphase formally announced it was developing a solid-state transformer in late April and released a presentation providing additional detail on the product. The company is engaging with potential customers and has a stated objective of launching pilot programs in 2027, with initial shipments anticipated in 2028. Goldman Sachs also hosted Enphase for an investor call in early May to discuss the market opportunity around the solid-state transformer.

Goldman Sachs has placed the total addressable market for solid-state transformers in the roughly 10 gigawatt range by 2030, which the firm equates to a revenue opportunity as high as $5 billion. Under its scenario analysis, Goldman projects that Enphase could capture revenue in 2030 ranging from $110 million on the low end to $910 million on the high end. Corresponding earnings estimates for Enphase in 2030 are placed between $0.21 and $1.75 per share.

The investment bank kept a Buy rating on Enphase Energy and raised its 12-month price target to $57 from $51. Goldman Sachs explained its target by applying a 22.5 times price-to-earnings multiple to its Q5-Q8 earnings per share estimate and then adding $5 of net cash per share.


Context and market implications

The developments tie Enphase into evolving requirements for AI data center infrastructure, particularly in the power conversion layer. If adoption of higher-voltage DC architectures materializes as outlined in the Nvidia roadmap referenced by Goldman Sachs, vendors of advanced transformer technologies would be positioned to address new efficiency and power density needs.

What remains to be seen

Enphase's timeline calls for customer pilots beginning in 2027 and commercial shipments starting in 2028. The company's engagement with potential customers and the investor call hosted by Goldman Sachs underscore active commercial outreach, but implementation and broader market adoption will determine how the opportunity translates to revenue and earnings in the coming years.

Risks

  • Timing and execution risk around Enphase’s stated plan to begin pilot programs in 2027 and initial shipments in 2028 - impacts capital equipment and data center infrastructure markets.
  • Competitive pressure from multiple technology vendors that plan to roll out advanced transformer technologies - affects power conversion equipment suppliers and OEMs.
  • Uncertainty inherent in Goldman Sachs’ market sizing and scenario estimates for 2030 - could influence revenue and earnings outcomes for Enphase and related suppliers.
