Sungrow Power Supply: AI Data Centers Open a New Blue Ocean for Energy Storage; Overweight Rating Maintained

Overview

This summary captures key takeaways from Sungrow Power Supply’s presentation at the J.P. Morgan Global China Summit. The central thesis is that the rapid expansion of Artificial Intelligence Data Centers (AIDCs) represents a new growth engine for Energy Storage Systems (ESS), and Sungrow has already secured orders in this domain. Although short-term gross margin pressure persists due to rising raw material costs, management expects global energy storage demand to grow robustly by 30–50% in 2026, and an improved geographic sales mix—particularly stronger shipments to high-margin overseas markets—will help mitigate profit headwinds. Accordingly, the firm maintains its 'Overweight' rating on the company.

Core views

AI Data Centers Emerge as a New Growth Engine for Energy Storage: Management views AI data centers as a significant new opportunity. Aging grid infrastructure and stringent reliability requirements make energy storage systems a natural solution to address power constraints at AI data centers. Key use cases include enabling 'grid-friendly' data centers, supporting fast startup capabilities, and potentially securing priority grid interconnection rights. Sungrow disclosed that it has already received energy storage orders from power developers supporting AI data centers. Optimistic Global Energy Storage Demand Outlook: Despite rebounding upstream raw material prices (e.g., lithium carbonate), management reaffirmed confidence in 2026 global energy storage demand growth, projecting year-on-year growth of 30–50%, corresponding to global installed capacity of 420–470 GWh (up from 317 GWh in 2025). Domestic China installations are expected to reach 200–250 GWh, while overseas markets—characterized by high visibility and strong underlying demand—are expected to sustain solid growth. Near-Term Cost Pressures and Structural Offsets: Q2 will face some margin pressure stemming from timing mismatches in revenue recognition: revenues recognized in Q1 largely reflect new orders placed in Q3–Q4 2025 (pre-price hike), whereas Q2 revenues will absorb costs incurred from Q4 2025 through Q1 2026 (post-price hike). Additionally, while some peers have attempted renegotiation or contract breaches, Sungrow remains committed to fulfilling all commitments to preserve long-term customer relationships. However, increasing shipments to high-margin markets such as Europe and the U.S.—expected to ramp up in Q4 2025 and Q1 2026—will improve revenue quality and partially offset the adverse impact of rising input costs. Competitive Advantages and Valuation: As the world’s largest photovoltaic inverter manufacturer (approx. 30% market share), Sungrow continues to gain market share thanks to cost advantages, superior product quality, and strong brand recognition. The firm applies a Sum-of-the-Parts (SOTP) valuation approach, assigning a 23x forward P/E multiple to each business segment (e.g., inverters, ESS, EPC), resulting in a target price of RMB 212.

Analysis framework

The firm updates its investment thesis primarily by incorporating the latest management guidance provided during investor meetings. Its analytical framework centers on a dual-driver narrative: 'new incremental markets (AI data centers)' plus 'resilient existing markets (global energy storage recovery)'. At the financial level, the analysis focuses on the time lag in cost pass-through and its short-term impact on gross margins, while also dissecting regional shipment mix shifts (e.g., Europe/U.S. vs. domestic China) to assess their net effect on overall profitability. Finally, integrating industry dynamics and the company’s competitive positioning, the firm derives its target price using the SOTP valuation methodology.

Methodology notes

• Valuation MethodologySOTP (Sum of the Parts) Valuation

  SOTP (Sum of the Parts) Valuation

  For diversified companies, this method separately values distinct business segments (e.g., inverters, energy storage, EPC) and sums them to arrive at an aggregate enterprise value. In this report, the firm assigns a uniform 23x P/E multiple to each segment, aggregating the results to derive the target price. This approach enables more granular assessment of value contributions across business lines.

• Industry/Industrial Analysis FrameworkSupply-demand framework

  Supply-Demand Balance and Price Transmission

  Analyzes how upstream raw material price increases (e.g., lithium carbonate) propagate through the supply chain to downstream players. The report notes that long-cycle orders introduce a time lag in cost transmission, causing temporary margin compression—a common cyclical phenomenon in manufacturing industries.

• Sungrow Power Supply (300274.SS)

  Primary beneficiary. As the leading PV inverter manufacturer and a major energy storage system supplier, the company stands to benefit directly from surging AI data center-driven energy storage demand and the broader global energy storage market recovery.

  Strengths

  World’s #1 PV inverter market share (~30%); cost leadership, high-quality products, and strong brand equity; early entry into AI data center energy storage supply chains; well-established presence in high-margin overseas markets.

  Weaknesses

  Near-term gross margin pressure from rising upstream raw material prices; time lag in cost pass-through due to long-cycle orders.

  Comparison

  Compared with other domestic peers, Sungrow enjoys stronger brand recognition and product quality overseas, and differentiates itself by honoring contractual obligations—unlike some competitors attempting renegotiation or breach.

  Risks

  Solar or energy storage installation growth falls short of expectations; pricing power and gross margin deteriorate; intensified domestic competition leads to market share erosion.

• Target PriceRMB 212Based on SOTP valuation using 23x forward P/E for 2026
• PV Inverter Market Share~30%Largest globally by production volume as of FY2024

Impact & implications

The report contends that the rise of AI data centers not only expands absolute energy storage demand but also elevates the strategic importance of ESS on the grid side (e.g., priority interconnection rights). For Sungrow, this implies its energy storage business is evolving beyond being merely a 'renewable energy complement' toward becoming 'critical infrastructure support', which could lift its valuation benchmark. Simultaneously, its proven capability to expand in high-margin overseas markets serves as a crucial moat to navigate near-term cost volatility.

Risks

• Solar or energy storage installation growth falls short of expectations
• Pricing power and gross margin deteriorate
• Domestic competitive intensity escalates beyond expectations

What to watch

• U.S. Department of Energy (DOE) follow-up decisions regarding priority grid interconnection rights for data centers
• Gross margin trends and regional shipment mix (especially U.S./Europe share) in Q2 2026 earnings
• Price trajectory of upstream raw materials (e.g., lithium carbonate) and progress of cost pass-through
