Sineng Electric Launches Next-Generation Residential Solar-Plus-Storage Solution at Intersolar Europe 2025

Munich, Germany, May 8, 2025 – Sineng Electric, a global leader in solar and energy storage solutions, announced the debut of its new-generation residential solar-plus-storage solution at Intersolar Europe 2025. Engineered to redefine home energy management, the battery system integrates cutting-edge technologies to deliver superior efficiency, intelligence, and safety.

Power for Ultimate Stability

Prioritizing user safety, Sineng’s home battery meets automotive-grade safety standards. Each battery pack comprises six 335Ah high-capacity cells and features aerospace-grade fire-resistant insulation, a comprehensive temperature detection system, and high-temperature resistant insulated pads. The solution has passed a series of rigorous safety tests—including module and cell puncture, as well as fire safety evaluations—demonstrating its industry-leading safety performance.

Power for Charging Efficiency

Built on a DC-coupled architecture and integrating a DC/DC converter with isolated topology, the system intelligently regulates charge and discharge currents, ensuring energy balance across battery packs. This eliminates the need for manual recalibration during capacity expansion and supports mixed use of new and old batteries, effectively mitigating the "bucket effect" and significantly extending the system's cycle life.

Power for Easy Installation

Featuring no cable connection, the system enables plug-and-play installation. Its modular design supports up to four battery packs per rack (up to 25.6kWh) and allows the parallel connection of up to four racks, achieving a maximum capacity of 102.4kWh. The plug-and-play design simplifies commissioning, lowers operation and maintenance (O&M) costs, and its scalable structure empowers homeowners with customized energy storage solutions tailored to their specific needs.

Power for 24/7 Safety

Engineered for durability, the system is IP65-rated for dust and water resistance and operates across a wide temperature range from -15°C to 50°C. It meets international safety and performance standards including IEC 62619, IEC 62477, and VDE 2510. With over 6,000 charge cycles and a 10-year warranty, the solution ensures long-term reliability.

Power for Smart Monitoring

Sineng's home battery, when integrated with a hybrid inverter ranging from 5.0kW to 15kW, forms a residential all-in-one solution. Paired with the EnjoySolar energy management platform, it provides homeowners with full visibility and control over their energy system—from generation to consumption. The platform enables real-time monitoring via mobile app or web interface and features multi-layer control rules to optimize power management. With seamless 10-millisecond off-grid switching, the solution guarantees an uninterrupted power supply during outages.

Through continuous innovation and technological excellence, Sineng Electric remains committed to empowering households worldwide with high-performance, smart, and reliable solar-plus-storage solutions—enabling homeowners to optimize energy consumption, enhance self-sufficiency, and achieve true energy independence.
