ShanghaiJune 4, 2026 /PRNewswire/ — On June 3, 2026, during SNEC PV 2026 at the National Exhibition and Convention Center (Shanghai), SGS, a globally recognized testing, inspection, and certification organization, officially awarded multiple certificates to Ningbo Deye Technology Co., Ltd. (hereinafter referred to as “Ningbo Deye”). Among these, the Deye Inverter SUN-(3-6)K-SG06LP1-EU-CM2 series received the Spanish grid connection certificate, and the GE-FX-BC-2-A3 rechargeable lithium-ion energy storage system obtained the CB certificate based on the IEC 62619 standard. Zheng Kai, Director of Renewable and Advanced Energy at SGS Connectivity and Electronic Electrical Services, along with Qiu Aiji, Director of the Ningbo Deye Inverter Testing Center, and Pan Jianping, Head of the Ningbo Dye Energy Storage Product Center, jointly attended the certificate presentation ceremony.

Spanish Grid Connection Approval Secured, Accelerating European Market Access
The Deye Inverter SUN-(3-6)K-SG06LP1-EU-CM2 series is a bidirectional converter designed for distributed photovoltaic systems. Unlike traditional unidirectional inverters that only convert direct current (DC) to alternating current (AC), this bidirectional converter not only converts DC generated by photovoltaic modules into AC for load use or grid connection but also supports power supply from the grid or energy storage systems to loads. It enables bidirectional power flow and flexible scheduling among photovoltaic systems, the grid, and energy storage systems, making it a key device for building integrated photovoltaic-storage systems. As a core component of photovoltaic systems, its performance directly impacts the safety, stability, and overall efficiency of power generation and energy use.
For photovoltaic equipment entering European markets such as Spain, meeting local grid connection requirements is a prerequisite for product deployment. The Spanish grid imposes strict technical specifications on grid-connected equipment, covering aspects such as anti-islanding protection, voltage and frequency adaptability, power quality control, and response capabilities under abnormal conditions. Therefore, before entering the market, relevant products must undergo testing and verification in compliance with local regulations and standards, and obtain corresponding grid connection certificates to achieve legal grid-connected operation.
The Deye Inverter SUN-(3-6)K-SG06LP1-EU-CM2 series has now obtained the Spanish grid connection certificate, indicating that the product meets the relevant standards for local grid access. Key indicators such as grid connection safety, power quality, and system stability have reached application standards. This achievement not only means the product has the basic conditions for entering the Spanish market but also demonstrates that its technical design and performance meet the entry thresholds of the European market, providing strong support for further international market expansion.

International Safety Verification Passed, Broadening Global Deployment Channels
The GE-FX-BC-2-A3 rechargeable lithium-ion energy storage system is a battery energy storage solution launched by Deye for industrial, commercial, and large-scale energy storage scenarios. Unlike traditional single-function power supply devices, this system uses lithium-ion batteries as its core, enabling efficient energy storage and releasing power during peak demand or load fluctuations to achieve peak shaving and energy dispatch. It plays a critical role in renewable energy integration and power regulation, serving as key supporting equipment for building new power systems. As an important component of energy storage systems, its safety and reliability directly affect equipment operational stability and user electricity safety.
In the process of entering global markets, meeting international safety standards is a crucial prerequisite for large-scale application of energy storage products. IEC 62619, as a key safety standard for industrial and energy storage lithium-ion batteries, imposes systematic requirements on battery systems in areas such as electrical performance, thermal runaway protection, overcharge and overdischarge protection, and safety performance under abusive conditions. Therefore, before entering international markets, relevant products must undergo testing and verification based on this standard and obtain corresponding certificates through the CB system to meet access requirements of different countries and regions.
The GE-FX-BC-2-A3 rechargeable lithium-ion energy storage system has now obtained the CB certificate based on the IEC 62619 standard, indicating that its key safety performance has passed international verification and meets the strict requirements for safety and reliability in energy storage systems. This achievement not only provides an important basis for the product to enter European and other overseas markets but also helps reduce redundant testing processes, improving global market access efficiency. It also reflects that the company has reached internationally advanced levels in product design, quality control, and safety management, laying a solid foundation for its continued global business expansion.
Zheng Kai, Director of Renewable and Advanced Energy at SGS Connectivity and Electronic Electrical Services, stated on-site: “Safe and reliable product quality is increasingly becoming a core focus for the industry and the market. As companies accelerate their expansion into the global photovoltaic and energy storage market, promoting reduced reliance on traditional energy sources and lowering greenhouse gas emissions, continuously improving product reliability and quality, and ensuring compliance with national regulations have become key foundations for achieving sustainable development. In the future, SGS will collaborate with Ningbo Deye, leveraging this partnership as an opportunity to further expand multi-field cooperation in global markets such as Europe, North America, Asia, Africa, and Latin America. We will continue to strengthen product safety and compliance capabilities, jointly promoting the high-quality development of the new energy industry and deepening the global green energy transition.”
