At Intersolar 2025, Deye redefines solar technology

Deye wowed the crowd at Intersolar Europe, one of the major solar industry shows, with its cutting-edge Power Conversion System (PCS), intelligent wireless energy management system, off-grid ESS solutions, and C&I ESS solutions. Hundreds of experts and partners visited the exhibit over the course of three days, demonstrating how intelligent energy is changing the direction of global energy development.

Both an indoor hall and an outside container zone were part of the display. Deye showcased their integrated PV storage solutions and HVAC equipment for ground power stations, business buildings, and residential settings indoors. It expanded the potential applications for solar storage by showcasing the Smart Home Micro-Climate Comfort Solution outdoors, which was fueled by its domestic energy storage system and Five Constant System.

Deye demonstrated its most recent PCS series, which offers smooth mode transitions in less than 20 ms and independent power channels of up to 500 kW for continuous diesel and on/off-grid operation. Zero-export control, time-of-use scheduling, a color touchscreen, and remote cloud management are all made possible by its clever EMS. It is suitable for medium to large-scale commercial and industrial applications, with a rated output of 2.5 MW and an efficiency of up to 98.5%.

The wireless smart energy management system from Deye, which uses LoRa for smart load control and home automation, was another widely discussed breakthrough. The power consumption strategy can be automatically optimized by this system using multi-dimensional logic control, which takes into account time, battery state of charge, and grid condition. Additionally, the Deye App allows for the integration of smart home IoT devices, like as wireless CTs, switches, plugs, and smart EV chargers, for remote control.

Due to its appropriateness for remote and microgrid applications, the recently introduced off-grid ESS technology garnered notice. It provides steady power in off-grid or weak-grid areas, such as deserts, and is compatible with diesel generators and batteries. While the integrated LoRa-based smart energy management system further enhances performance and monitors in off-grid applications, its IP65 protection level increases durability and prolongs operating lifespan.

In addition, Deye’s C&I ESS series offers a scalable, high-performance solution for diverse business needs. The MS-G215 outdoor system features peak-valley management, anti-back flow protection, intelligent thermal control (<35℃ battery temp), and supports parallel expansion up to 20 units (on/off-grid) or 5 units (backup). The integrated PV-BESS-EV solution (MS-DCC180-2 + MS-LC430) combines solar, storage and fast charging with key advantages including:

Improving system efficiency by 4% and cutting investment by 15%.
Supporting flexible 2-8 hour energy storage.
Providing 3+3-layer electrical protection against thermal runaway.
Achieving efficiency and safety with 180kW ultra-fast charging and up to 4 dual-gun terminals.

For high-capacity energy storage, the utility C&I PV-BESS solution delivers 430 kWh per unit with excellent scalability and active balancing. It ensures optimal battery efficiency and lifespan while adapting to diverse industry requirements, making it ideal for applications across commercial, industrial, and utility sectors.

Beyond the product display, the exhibition marked a milestone in Deye’s global strategy. Its F120 Series ESS earned CEI 0-21 and 0-16 certifications from Kiwa for Italy’s medium-voltage grids, while TÜV Rheinland granted VDE-AR-N 4110 & 4120 certifications to its flagship ESS and 110 kW three-phase inverter. Attendees also experienced Deye’s latest innovations through an immersive VR showcase, which further reinforced its international tech leadership.

With Intersolar Europe 2025 behind it, Deye now looks to global expansion, focusing on technology refinement and deeper global partnerships. “Our vision is clear,” stated Deye’s representative. “To empower communities, businesses, and grids with smart, sustainable energy. Intersolar confirmed we’re on the right path- and the world is ready.”
