Leading global provider of smart energy solutions SINENG Electric stole the spotlight at Intersolar Europe 2025 with its full-scenario PV-ESS (Photovoltaic-Energy Storage System) lineup and a revolutionary residential PV-ESS solution, cementing its position as a driver of renewable energy innovation.
Residential PV-ESS: Redefining Home Energy Autonomy
Tailored for European households seeking energy independence and cost efficiency, SINENG’s new residential PV-ESS integrates automotive-grade battery cells with a DC-coupled architecture and AI-driven safety systems to deliver seamless energy management. The system achieves real-time dynamic energy balancing through adaptive algorithms, optimizing power distribution between PV generation, battery storage, and grid consumption. Its plug-and-play design combines an IP65-rated enclosure with a -15°C to 50°C operating range, enabling hassle-free installation and maintenance. The system further enhances user control via the EnjoySolar App, which offers grid-interactive charging/discharging optimization, leveraging AI to predict household energy demand and adjust strategies to minimize grid dependency. For safety, the solution incorporates arc-fault circuit interrupters (AFCI), temperature monitoring, and overvoltage protection, ensuring stable operation even under fluctuating environmental conditions.
C&I and Utility-Scale Breakthroughs
SINENG’s commercial, industrial, and utility-scale solutions underscore its commitment to pushing technical boundaries:
The 125kW string inverter, designed for C&I applications, features a 75kg ultra-lightweight chassis and 1500Vdc high-voltage platform, reducing balance-of-system (BOS) costs while supporting high-power-density module configurations. Its triple safety mechanisms—AFCI, overvoltage/overcurrent protection, and real-time temperature monitoring—ensure reliability in industrial environments.
For utility-scale PV plants, the 350kW string inverter offers six MPPT channels and thirty string inputs, enabling flexible layout design across complex terrains. The system achieves a 12-year lifespan through IP66/C5-M corrosion-resistant housing, while its 12-string fault isolation capability minimizes downtime from module-level failures.
The 4.4MW central inverter, expandable to an 8.8MW integrated unit, leverages a 1500Vdc high-voltage platform to reduce AC/DC conversion losses by 1.5%, lowering the levelized cost of electricity (LCOE) by 8%. Its grid-forming capabilities support black-start functionality and frequency regulation, making it ideal for hybrid microgrids integrating wind, solar, and storage.
In the energy storage sector, the 430kW liquid-cooled string PCS (Power Conversion System) sets a new benchmark for efficiency. By combining 587Ah+ battery compatibility with low-power liquid cooling technology, the system reduces thermal losses by 40% and extends battery lifespan. Its cluster-level control enables precise state-of-charge (SOC) management, boosting return on investment (ROI) by 7% through optimized charge/discharge cycles.
For critical power applications, the 1250kW central PCS (Grid-Forming Edition) delivers 1.5x overload capacity and zero-voltage black-start capability, restoring power in under 10ms without external grid support. Its seamless off-grid switching technology eliminates power interruptions for hospitals, data centers, and industrial facilities, even during prolonged grid outages.
