Sineng Electric has 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.
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.
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 lifecycle.
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.
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 and, with over 6,000 charge cycles and a 10-year warranty, the solution ensures long-term reliability.
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.
