On April 1st, the 14th International Energy Storage Summit and Exhibition (ESIE 2026) grandly opened at the Beijing Capital International Convention Center. TBEA New Energy Company prominently launched two key new products defining the next-generation standards: a grid-forming string energy storage inverter and a 500kW string photovoltaic inverter. The overall booth presentation centered around these two new products as technological anchors, showcasing a complete, coordinated smart energy ecosystem. This not only demonstrates their deep expertise and leading breakthroughs in core power electronics technology but also marks a new stage in their “PV + Energy Storage” deep integration strategy characterized by “extreme density, full-chain intelligence, and active support.” Simultaneously, the company also displayed a full range of solutions covering power supply, grid, and user sides, fully demonstrating their technological strength and ecological layout in helping build a new power system worldwide.

New Generation “Heart” and “Engine” of the System Simultaneously Innovate

During the exhibition, the two new products released target the core electrical energy conversion stages of energy storage systems and photovoltaic power generation, respectively, serving as the “heart” and “engine” of the new energy system. Their synchronized upgrade aims to systematically address key industry challenges such as high-density deployment, grid-friendly interaction, and lifecycle cost reduction.

1. Smart Energy Storage “Heart”: String Liquid-Cooled Inverter

This product is a thorough overhaul of TBEA New Energy’s core component of energy storage systems—the inverter (PCS). Its biggest highlight is the adoption of fully intelligent liquid cooling and ultra-high power density integration design. Through innovative topology and thermal management, it achieves a smaller volume and lighter weight at the same power level; compared to previous models, both volume density and weight density are significantly improved. This allows for a substantial reduction in the footprint of energy storage stations, making it especially suitable for land-scarce or retrofit projects, directly lowering initial investment and land costs.

TE435/392K-HV not only surpasses physical compactness but also functions like a “smart heart” with “independent thinking and supporting capabilities.” Paired with a high-speed control platform, it possesses grid-forming ability, enabling seamless millisecond-level switching with grid-following mode. This means it can adapt to various grid environments from very strong to very weak, and actively provide inertia support, fast frequency regulation, and even black-start services, transforming from a simple “power transporter” to an “active participant” in maintaining grid stability. Combined with high protection levels and multiple active safety designs, it ensures ultra-high reliability under various harsh environments while pursuing extreme compactness.

2. Photovoltaic “High-Efficiency Engine”: String Photovoltaic Inverter

On the PV side, TBEA New Energy has pushed the single-unit power of string inverters to a new global height of 500kW. The product is designed for 5/5.5MW large photovoltaic plant sub-arrays, supporting higher voltage platforms of 1600V DC and 1000Vac AC, effectively reducing system line losses and balancing system costs. Compared to mainstream 330kW solutions, it is expected to bring significant initial investment savings for power plants.

“This product is better suited for weak grid environments and offers higher power generation efficiency,” said Zhou Hongwei, General Manager of TBEA New Energy Western Science Company. The new product can deliver better power generation returns for customers, applicable to industrial and commercial projects as well as large ground-mounted plants. The core of the “engine” uses third-generation silicon carbide (SiC) semiconductor devices, which not only improve conversion efficiency but also enhance power density and reliability. The product features an ultra-wide operating temperature range of -40℃ to 70℃ and can operate at high altitudes up to 5000 meters without derating, demonstrating unparalleled environmental adaptability. Regarding grid connection, it adopts voltage source control technology, capable of actively supporting grid voltage and frequency, with a power response time within 20 milliseconds, greatly improving the response speed and support strength of PV plants to grid dispatching commands, aiding grid stability under high renewable penetration.

Full-Scenario Solutions Empower Energy Transition

TBEA New Energy showcased a complete, coordinated smart energy ecosystem at the exhibition. The booth featured a BPS integrated AC/DC energy storage system with modular prefabrication, land-saving, and rapid deployment advantages, providing optimal engineering solutions for both user-side and grid-side energy storage. The string inverter booster station employs “mass control technology” to achieve millisecond-level unified response of energy storage stations, improving overall efficiency. To meet the booming distributed market, the company also presented a new distributed PV-storage integration solution covering residential, industrial, commercial, and microgrid scenarios, maximizing self-consumption of green electricity and enabling intelligent dispatch.

Driven by the “dual carbon” goals, green power transformation has become a core topic in residential and industrial-commercial fields. To meet diversified, scenario-based smart energy needs, TBEA New Energy also introduced its new distributed PV-storage integration system solution at this event. This solution is not a simple stacking of PV, energy storage, and monitoring devices but centers on “efficient collaboration and intelligent management,” deeply integrating three major modules to build a self-optimizing, smartly dispatched “source-grid-load-storage” micro-energy network.

The solution supports rapid switching between grid-connected and islanded modes, as well as black-start capability, allowing flexible operation mode changes based on different scenarios. Its product matrix covers from 8–150kW distributed PV inverters, 5–15kW residential hybrid PV-storage inverters, to modular commercial energy storage systems starting at 125kW/261kWh, forming a complete power segment layout. This enables the solution to serve both energy-saving, backup power, and green power needs for residential villas, as well as meet high-reliability power supply and power management requirements for commercial buildings, industrial parks, and charging stations. It also offers customized one-stop solutions for high-energy-consuming enterprises like steel and chemical industries, addressing core pain points such as load management, peak-valley arbitrage, and emergency power supply.

In the future, TBEA New Energy will continue to deepen “PV-storage integration” technology, focusing on high efficiency, safety, intelligence, and reliability, providing global customers with full-lifecycle, adaptable solutions for all application scenarios, working with partners to promote clean, low-carbon energy transformation and contribute to global climate change mitigation.
