A Visionary Leader at the Helm! 20 Years of Top-Tier Experience Bolsters R&D Confidence

The newly appointed R&D leader, Mr. Haoxing Liu, is an industry-leading talent combining "technological foresight, engineering execution, and system building." With 20 years of top-level R&D and management experience in power electronics and energy storage systems, his resume is unmatched in the industry:

• ■Deeply involved in the R&D of Huawei's first full soft-switching grid-tied inverter, achieving industry-leading conversion efficiency;
• ■Spearheaded Kehua Data's modular UPS development from scratch, with core metrics reaching world-class standards;
• ■Cultivated years of expertise in magnetic technology at Delta Electronics, with profound experience in high-end inductor and transformer design;
• ■Focused on micro-energy storage, residential storage, and balcony solar-storage in recent years, holding a mature product matrix and independent intellectual property rights.

One visionary leader plus a full-stack R&D team directly elevates TSUN's R&D capabilities to the industry's top tier, injecting core momentum into our technological leap! Furthermore, supported by TSUN's top-tier capital backing, targeted empowerment from high-quality government resources, a mature and comprehensive marketing system, and professional endorsement from top industry investors, combined with the profound technical expertise of the new team and TSUN's dominant position in the microinverter sector, TSUN has now gathered all the core elements needed to sprint toward becoming an industry benchmark.

Leap to Full-Stack In-House R&D! From Single-Point Leadership to System-Wide Dominance

This team expansion is by no means a simple talent acquisition, but a strategic restructuring of TSUN's R&D system—achieving a complete leap from "single-point technological breakthroughs" to "end-to-end full-stack in-house R&D"!

The team has built a closed-loop R&D operational system covering new technology pre-research, product design, validation and testing, quality control, NPI (New Product Introduction), and smart manufacturing, realizing a triple leap in R&D efficiency, iteration speed, and delivery quality. This R&D team has long provided professional technical solutions in the fields of micro-storage, residential storage, and C&I (Commercial & Industrial) energy storage for top domestic enterprises. They have accumulated abundant mature product solutions and independent IP rights, continuously deepening TSUN's technological moat.

Dual Core Barriers! Redefining Balcony Energy Storage Standards

• ■Ultimate Safety DNA: Injecting the stringent reliability standards of the power supply field into energy storage R&D, embedding safety, stability, and uninterrupted power supply into the foundational layer of our products to completely resolve industry pain points.
• ■Precise Scenario Adaptation: Combining grid-tied microinverter technology with load-side application insights. Based on real-world scenarios such as homes and balconies, we create an overwhelming differentiation in load adaptation, dynamic response, and user experience.

Consolidating the Product Matrix: Three Strategic Values Highlighted

• ■Strengthening Core Product Line Advantages: Further consolidating the "solar-as-a-home-appliance" energy storage product matrix, especially forming stronger technical support in the balcony micro-storage track to solidify our leading industry position.
• ■Enhancing R&D Conversion Efficiency: Relying on a mature development system to achieve efficient advancement of new products from R&D to mass production, accelerating the iteration pace, and precisely capturing energy storage market opportunities.
• ■Perfecting the Integrated R&D and Manufacturing Layout: Assisting the company in building a more comprehensive R&D and smart manufacturing system, providing fundamental support for large-scale productization and global market expansion.

Resounding Investment in R&D! Long-Termism Fortifies Global Competitiveness

• ■R&D personnel account for over 35% of the workforce, with core members each possessing over ten years of deep industry experience;
• ■Accumulated over a hundred independent intellectual property rights, building complete technological barriers;
• ■Taking the Suzhou R&D Center as the core to achieve an "R&D - Manufacturing - Market" flywheel cycle;
• ■Business covers over 40 countries and regions globally, including Europe, Latin America, Asia-Pacific, and Southeast Asia, maintaining a top position in core markets.

Strategic Elevation! Aiming for Absolute Global Leadership in Balcony Energy Storage

In the past, TSUN established its industry position with high-power microinverters. Today, backed by elite "Huawei DNA," mature in-house IP, and proven market success, TSUN is going all-in on micro-energy storage and heavily investing in the balcony micro-storage track, achieving a comprehensive transformation from a single-item leader in microinverters to a full-domain solution provider for integrated solar and storage.

In the future, TSUN will utilize stronger determination, a more elite team, and more sustained investment to fortify technical barriers and accelerate global expansion. We will use hardcore strength to instill maximum confidence in the industry, our customers, and our investors. We are fully committed to building the absolute global leader in the fields of micro-solar storage and balcony micro-storage, making every ray of sunlight a manageable source of clean energy for families!
