Long Cycle Life
Cycle life is one of the most critical factors for commercial and industrial energy storage projects, as it directly impacts system reliability and long-term return on investment. This solar battery storage cabinet is built with high-quality LiFePO₄ battery cells, delivering a cycle life of ≥8000 cycles at 25°C, 0.5C, and 90% depth of discharge, while maintaining 70% end-of-life capacity.
Compared with conventional battery chemistries, LiFePO₄ offers superior thermal stability and slower capacity degradation, making it particularly suitable for high-frequency charge and discharge applications such as peak shaving and solar energy storage. The long cycle life significantly reduces battery replacement frequency over the project lifetime, helping system owners and EPC contractors achieve lower operating costs and more predictable performance across years of continuous operation.
