Deye Unveils Sustainable Energy Tech at SNEC 2025

Shanghai, China – Deye presented its portfolio of intelligent energy solutions for residential and commercial & industrial (C&I) sectors at SNEC 2025. Key products featured included the SE-F "Neptune" series, SUN-20K-SG05LP3 and SUN-80K-SG02HP3 inverters, RW-L10.2 and BOS-A batteries, MS-LC430 series, and the Deye Copilot design. The company also demonstrated system solutions like its smart energy management and HVAC systems, highlighting its focus on new energy innovation and a smarter, greener future.

Residential Focus: Enabling Smart Home Energy

The newly launched SE-F "Neptune" residential battery series attracted significant interest. Offering flexible 5/12/16kWh modular capacity and broad inverter compatibility, it integrates seamlessly with all Deye low-voltage hybrid/off-grid inverters and mainstream brands. All models support Bluetooth local monitoring, with the SE-F5 Pro adding optional Wi-Fi for remote access. Advanced BMS and active fuse technology provide protection against overcharging, discharging, short circuits, overheating, and shock.

Deye also exhibited the SUN-20K-SG05LP3 hybrid inverter alongside the compatible RW-L10.2 battery. This 20kW three-phase low-voltage inverter supports up to 32kW PV input and AC coupling. It features a 6-period Time of Use setting for intelligent energy management and a 4ms switchover time for uninterrupted power. The RW-L10.2 battery, with a 2C discharge rate and over 6,000 cycles, contributes to long-term system reliability.

For intelligent home energy control, Deye introduced a smart energy management system integrating solar, storage, and devices. Key components include a Smart Transmitter (IoT hub), plug-and-play Smart Plug, Wireless CT for power monitoring, Smart EV Charger, and versatile Smart Switch. LoRa-based communication ensures lower latency, instant response, and stable operation.

C&I Solutions: Driving Sustainable Productivity

In the C&I segment, Deye featured the SUN-80K-SG02HP3 inverter paired with BOS-A battery groups. The inverter, with 6 MPPTs and 12 strings, maximizes harvest and supports 128kW PV input (1.6 DC/AC ratio). It offers 100% unbalanced output, AC coupling for system upgrades, and parallel capability (up to 10 units). It stores energy from diesel generators and provides six battery charge/discharge periods, achieving 98.5% peak efficiency. The scalable BOS-A battery (54kWh-160kWh via 7 to 21 packs) offers flexible storage. Fire-resistant construction, dual-electrode disconnection, and 160A output enhance safety and durability.

The BOS-B&PCS+MPPT+STS C&I ESS Solution was also displayed. Each 215kWh cluster (15 modules) supports 168A charge/discharge current, with up to 16 clusters parallel per PCS for 32 hours backup. Combined with 100kW-2.5MW PCS, MPPT (8×40A), and STS (<20ms switching), the system delivers high efficiency and fast response.

The MS-LC430 series was noted for its integrated PV-BESS-EV charging design. The system includes a 430kWh AC/DC BESS, 420kW DC power cabinets, and 180kW dual-gun chargers (supporting up to 10 parallel units and 2-8 hour storage). 3+3 fire and electrical safety protection, plus 24/7 online O&M, ensure safe, intelligent management across scenarios.

Beyond Products: Strategy and Recognition

Deye also showcased its Deye Copilot for managing air quality, lighting, temperature, humidity, batteries, and inverters. An intelligent villa solution integrating PV, solar water pumps, solar heat pumps, ESS, and air quality control via the HVAC system was presented.

The event marked progress in Deye's global strategy. The company was honored with the Trusted Partner Award from Festa Solar and GreenEdge Energy. Product certifications secured include TÜV Rheinland’s VDE-AR-N 419 for the PCS and SGS’s AS60947.3 for the SUN-(14-20)K-SG05LP3 series.

While SNEC 2025 concluded, Deye continues its innovation path. Adhering to its "Green Industry Better Future" vision, the company remains dedicated to developing high-performance, cost-effective storage solutions for the global transition to sustainable energy.
