Sineng Electric Showcases Its Latest PV+ESS Solutions at Intersolar Europe 2025

Munich, Germany, May 9, 2025 – Sineng Electric, a global leader in solar and energy storage solutions, unveiled its latest innovations in PV and energy storage technologies at Intersolar Europe 2025. With an extensive product lineup covering residential, commercial & industrial (C&I), and utility-scale applications, Sineng garnered significant attention throughout the exhibition, sparking widespread industry discussions and inquiries.

Keep Home Powered with Residential Solar-Plus-Storage Solutions

Sineng introduced its newly developed residential solar-plus-storage solution, engineered for unmatched safety, scalability, and performance. Each battery pack integrates six high-capacity 335Ah automotive-grade cells and is equipped with a DC/DC module to enhance system balance. The battery system has passed a series of rigorous tests—including module puncture, cell puncture, and fire safety tests—ensuring 24/7 operational safety. Its modular architecture supports up to four battery packs per rack (up to 25.6kWh), and up to four racks in parallel, enabling a maximum capacity of 102.4kWh.

The battery, when paired with Sineng's 5-15kW three-phase hybrid inverters, forms an all-in-one solution that has recently received CEI 0-21 certification from DEKRA, marking a major step in Sineng's expansion across the European market.

Empowering Low-Carbon Operations with C&I Solar Solutions

In the commercial and industrial segment, Sineng highlighted the 125kW string inverter(SN125PT), a powerful solution enabling 1.1x continuous output overload for optimized energy yields. With its high energy density, compact 75kg design, and integrated safety features—including the smart switch—this inverter helps businesses to reduce electricity costs while decarbonizing their operations.

Scaling Up Clean Energy Deployment with Utility-Scale PV Solutions

For utility-scale applications, Sineng showcased its 350kW string inverter (SP-350K-HB1) and 8.8MW MV turnkey station (EP-8800-HA-UD/20~35). The next-generation 350kW string inverter offers a maximum output of 352kW and supports up to 75A per MPPT, making it fully compatible with high-efficiency bifacial modules. With a DC/AC ratio of up to 2.0, the inverter contributes to reduced LCOE, while smart DC switches and temperature detection on DC terminals enhance system reliability and safety.

Complementing this is the 8.8MW MV turnkey station, configured with two units of 4.4MW central inverters, each equipped with four MPPTs. The inverter delivers up to 99% efficiency and integrates Sineng's patented PID function. By incorporating multi-layer protections and smart thermal management, the inverter guarantees long-term, stable performance in diverse environments.

Advancing Energy Storage with Liquid Cooling Technology

Sineng also introduced its cutting-edge 430kW string PCS, setting new benchmarks in high-power energy storage solutions. Leveraging advanced liquid cooling technology, it helps achieve balanced heat dissipation and reduces temperature rise by 5K, extending operational life to over 25 years. It further improves round-trip efficiency (RTE) by 0.2%, reduces auxiliary power consumption by 30%, and increases lifecycle charge and discharge capacity by over 7%. Furthermore, the 430kW PCS supports scalable configurations ranging from 3200kW to 12500kW, offering exceptional flexibility for diverse project requirements.

Alongside, Sineng showcased its 1250kW central PCS, designed for integration into a 10MW MV turnkey solution. With grid-forming capability, triple overloading capacity, and black start functionality, the solution ensures grid stability under demanding conditions.

Strengthening Strategic Partnerships Across Europe

During the event, Sineng signed strategic cooperation agreements with BELECTRIC, NextGEN Energy and Europower Enerji. These partnerships reinforce Sineng's commitment to advancing clean energy adoption across Europe and beyond. Meanwhile, the expert-led sessions drew large crowds to Sineng's booth, where audiences explored the full range of PV+ESS solutions.

"Our presence at Intersolar Europe 2025 reflects our relentless pursuit of innovation and commitment to delivering customer-centric solutions," said Qiang Wu, Chairman of Sineng Electric. "By staying aligned with the evolving needs of the global energy sector, we continue to provide reliable, efficient, and forward-looking technologies that empower our partners and end-users."
