Sungrow's EnerNeo SST product makes its debut; Jefferies sees AIDC power equipment opening a new growth curve

Overview

This report is Jefferies' company research update on Sungrow Power Supply Co Ltd (300274 CH), focusing on the EnerNeo SST solid-state transformer formally launched by Sungrow on July 9, 2026. The report believes that EnerNeo, designed for all-scenario AIDC power architectures, could become an important driver of the company's next phase of growth, supported by high efficiency, high power density, modular maintenance, digital twin capabilities, and a global manufacturing base.

Core views

The core views are: first, EnerNeo's technical specifications and product form factor fit AI data centers' needs for high power density, high reliability, and rapid deployment; second, although actual hyperscaler orders will take time, management remains confident in progress with 2-3 major customers; third, the company's SST technology accumulation can be traced back to 2015 and has already been validated in PV and energy storage applications, forming a certain technological moat; fourth, SST will expand from AIDC to ultra-fast charging, energy storage, PV, wind power, and hydrogen energy, enlarging the addressable market.

Analysis framework

The report combines company event analysis, a breakdown of product technical specifications, commercialization timeline assessment, a review of accumulated technology, and SOTP valuation. The valuation is based on 20x FY2027 EPS and discounts the estimated 2030 market value of RMB162bn for the AIDC ESS and power supply businesses, including SST, by three years, resulting in a target price of Rmb236.35 per share.

Methodology notes

• Valuation methodsSOTP segment valuation

  Valuing the mature core business separately from new businesses such as AIDC ESS and power supply

  Jefferies uses 20x FY2027 EPS and discounts the estimated 2030 market value of the AIDC ESS and power supply businesses to derive the company's target price.

• Valuation multiplePER

  Price-to-earnings valuation

  The report applies a 20x PER to FY2027 EPS to reflect the company's earnings power and growth expectations.

• Product analysisTechnology roadmap and commercialization milestones

  Assessing the pace of new business realization based on product specifications, customer feedback, mass-production timelines, and application expansion pathways

  The report focuses on tracking the SST prototype, mass production, US commercialization, UL certification, outdoor versions, and cross-scenario application expansion to assess the path from EnerNeo's launch to orders and revenue contribution.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Sungrow Power Supply Co Ltd (300274 CH)

  The company covered in the report; Jefferies assigns it a BUY rating and a Rmb236.35 target price

  Strengths

  A globally leading PV inverter foundation, nearly 30 years of power electronics experience, more than 10 years of accumulated SST R&D, global manufacturing bases, and a clear product roadmap.

  Weaknesses

  AIDC customer orders still require time for validation, while SST products remain in the stages of continuous customization based on customer feedback and pre-commercialization advancement.

  Comparison

  Compared with a standalone PV inverter thesis, the report places greater emphasis on the new growth curve from AIDC power supply, SST, and ESS.

  Risks

  Solar installations below expectations, energy storage system growth below expectations, customer orders materializing more slowly than expected, and uncertainty surrounding US policies or certification timelines.

• EnerNeo SST

  Sungrow's next-generation solid-state transformer product launched for AIDC

  Strengths

  High efficiency, high power density, modularity, lightweight design, digital twin capabilities, support for NVIDIA DSX integration, and coverage of AIDC power supply needs at different scales.

  Weaknesses

  It still needs to undergo prototype, mass production, certification, and commercialization validation, and actual orders from major customers have not yet materialized immediately.

  Comparison

  Compared with traditional power equipment, the report states that EnerNeo can reduce space and delivery time by 50% while improving maintenance convenience.

  Risks

  Changes in customer specifications, product validation cycles, mass-production ramp-up, and reliability validation could affect the pace of revenue realization.

Impact & implications

If EnerNeo successfully passes customer customization, certification, mass production, and commercialization validation, Sungrow could further enter AIDC power infrastructure from its traditional PV inverter and energy storage businesses, enhancing its long-term growth potential and valuation upside. Near-term share price catalysts will still depend on hyperscaler order wins, US commercialization progress, UL certification, and the launch of outdoor high-voltage versions.

Risks

• Solar installations fall below expectations.
• Energy storage system growth falls below expectations.
• Actual hyperscaler orders are secured later than expected.
• SST product certification, mass production, or US commercialization progresses more slowly than management's timeline.
• Changes in US policies, supply chains, and customer customization requirements could affect the progress of AIDC-related businesses.

What to watch

• Validation progress and actual orders from 2-3 major customers.
• The launch of the indoor standard SST with UL certification in 2026.
• Progress on the 13.8kV outdoor version in 1Q27.
• Progress on the 35kV, 6-12MW outdoor version in 2H27.
• Orders, revenue, and profit contributions from the AIDC ESS and power supply businesses.
• The pace of SST deployment across ultra-fast charging, energy storage, PV, wind power, and hydrogen energy applications.
