On June 23, 2026, The smarter E Europe—Europe’s largest exhibition for solar energy and battery storage—officially opened at Messe München in Germany. At the event, Deye introduced a comprehensive portfolio of innovative PV and energy storage solutions covering residential, commercial & industrial (C&I), and utility-scale applications. With advanced hardware and software architectures and outstanding system performance, Deye aims to meet the growing demand for energy transition across Europe and neighboring markets.
Flagship Upgrade: 6th Generation Residential Energy Storage Inverter
At the exhibition, Deye unveiled its sixth-generation low-voltage residential energy storage inverter, the SG06 series. As a fully upgraded flagship product, it incorporates third-generation semiconductor material silicon carbide (SiC) along with optimized circuit and structural design. This results in a more compact form factor and significantly reduced weight, greatly improving the overall experience from transportation to installation. TÜV Rheinland, a globally recognized third-party testing and certification body, awarded the product its German certification on-site.
Micro Storage Breakthrough: A New Green Power Engine for Apartments
In response to the rapid growth of balcony PV systems and lightweight plug-and-play storage demand, Deye introduced micro energy storage systems with capacities of 2.56 kWh and 5.12 kWh. As an advanced product in Deye’s micro storage lineup, the 5.12 kWh system not only retains the widely recognized features of “plug-and-play” and “stackable expansion,” but also delivers a significant leap in capacity and endurance. With its ample energy storage, apartment households can increase self-consumption of green energy without complex grid modifications, while ensuring reliable backup power for daily use.
High-Voltage Advancement: Redefining Installation Efficiency
For high-demand residential and small C&I applications, Deye showcased its third-generation outdoor high-voltage battery system, NEPT G Plus. With a single cluster capacity ranging from 11.52 kWh to 69.12 kWh, it is fully compatible with Deye’s 10–60 kW three-phase high-voltage hybrid inverters. The system adopts a modular, cable-free stacking design, significantly reducing battery weight and height, enabling fast installation by just two people—effectively addressing high labor costs in the European market. Its optimized vertical space utilization also allows flexible deployment in challenging installation environments.
Full Coverage: Indoor and Outdoor C&I Solutions
To address diverse C&I energy storage needs in both indoor and outdoor scenarios, Deye presented a range of differentiated solutions.
Indoor C&I Solutions
A highlight of the indoor segment was the newly launched ORION W series GB-W battery system. Designed for space-constrained environments such as office buildings, it features a highly integrated compact structure and excellent modular scalability, with a maximum capacity of up to 192 kWh per cluster. This significantly reduces initial investment costs while allowing capacity expansion in line with business growth. SGS, an internationally recognized testing and certification organization, awarded the GB-W lithium-ion energy storage system the IEC 62619 CB certificate on-site.
In addition, Deye introduced two 125 kW solutions: a fully integrated energy storage inverter-based system and a modular PCS + MPPT + STS configuration. The latter supports parallel connection of multiple STS and PCS units, achieving up to 2.5 MW system capacity. Thanks to its modular design, the system can be flexibly configured with MPPTs, STS, and various battery systems to meet diverse application needs such as PV integration, off-grid power supply, and backup power.
Outdoor C&I Solutions
For large-scale outdoor applications such as industrial parks, Deye showcased a solution combining its 125 kW three-phase high-voltage inverter with the ORION E series GE-F256 outdoor battery cabinet. The inverter supports up to 200% PV oversizing and features 10 independent MPPTs, significantly improving energy yield under complex rooftop conditions. Its scalability allows up to 10 units in parallel, enabling easy deployment of megawatt-scale energy storage systems. With UPS-level seamless on/off-grid switching and 150% peak overload capacity, the system ensures continuous power supply even under heavy load startup or grid fluctuations. The product received EN 50549-2 certification from TÜV Rheinland during the event.
PV-Storage-Charging Integration: Reshaping Commercial Energy Models
Deye’s MC-LC430-2H2 PV-storage-charging solution integrates solar generation, energy storage management, and EV charging into a single system. With a highly integrated design and built-in fire protection and electrical safety systems, it ensures reliable and stable operation for commercial applications. The system supports parallel expansion of up to 10 cabinets, making it ideal for high-power, high-frequency EV charging scenarios and supporting the development of green mobility.
Containerized Energy Storage Systems
For large C&I projects, renewable integration, and grid-side energy storage applications, Deye presented a range of containerized energy storage solutions across different capacity levels. Based on standard 20-foot container design, these systems enable pre-installation, pre-commissioning, and rapid deployment, reducing on-site construction complexity and shortening project timelines. Deye’s portfolio includes the WS-GS2000-2H3, WS-L4300-BC-3, and WS-L5000-BC-2 series, covering applications from C&I to utility-scale storage. TÜV Rheinland awarded the WS-L5000-BC-2 system both TÜV Mark and CE-LVD certifications at the exhibition.
Strategic Partnerships: Building a Global Energy Ecosystem
While advancing PV and storage technologies, Deye continues to expand its global partnership network. During the exhibition, the company reached strategic agreements with several key industry partners.
On June 23, Deye signed a cooperation agreement with OSW Energy, a well-known distributor of PV and storage solutions, focusing on energy applications, smart energy management, and localized service systems in Australia and the Benelux region.
On June 24, Deye also signed a strategic cooperation memorandum with CMC, a European renewable energy developer and EPC company. The collaboration will focus on large-scale energy storage project development, EPC system integration, localized service infrastructure, and long-term O&M capabilities, jointly accelerating Europe’s energy transition.
Deye remains committed to innovation-driven development, continuously addressing the energy challenges of diverse markets and application scenarios. Its strong presence at The smarter E Europe 2026 highlights both its technological expertise and its determination to deepen its footprint in Europe while empowering global green development.
Looking ahead, Deye will continue working with global partners to deliver more efficient, safer, and smarter energy solutions, driving the industry toward a zero-carbon future.
