The Residential ESS Solution (RW-L Series) consists of low-voltage, modular batteries designed for PV self-consumption and backup power, optimized for easy installation in homes or small businesses. A key feature is the LiFePO4 (LFP) chemistry - cobalt-free, thermally stable, and less prone to overheating than standard NMC, resulting in higher safety and longer lifespan during daily operation.

The RW-L features a smart BMS with active cell monitoring and integrated protections, enabling the system to better handle load fluctuations and emergency mode operation. For users, the high capacity for over 6,000 cycles and 10-year warranty are crucial - practically ensuring long-term operation without noticeable degradation under typical home scenarios.

The series is scalable - multiple modules can be connected in parallel, making it easy to expand the installation as energy consumption increases or to add storage to an existing hybrid system. This solution is designed for integration with hybrid inverters and backup systems, suitable for off-grid applications (with appropriate installation configuration).
