The BESS-125K215 All-in-One Energy Storage System is engineered to deliver superior stability, flexibility, and long-term performance for commercial and industrial energy applications. Built with high-quality LiFePO₄ battery cells, it offers a nominal energy capacity of 215.04 kWh, battery voltage of 51.2 V, and a 280 Ah high-capacity configuration, ensuring excellent energy density and long service life. With a cycle life of over 6,500 cycles.
1. Advanced Cooling & Safety
A built-in intelligent air conditioning module ensures optimal temperature regulation, maximizing battery longevity and performance. The system is designed with comprehensive multi-layer safety protections, while the IP65 ingress rating supports deployment in harsh outdoor environments without compromising reliability.
2. High PV Compatibility & Enhanced Power Performance
The BESS-125K215 supports PV input up to 200% of the inverter’s rated DC power, allowing customers to capture more solar energy and significantly increase renewable energy utilization. Its 21A PV input current ensures compatibility with the latest high-power PV modules.
In off-grid mode, the unit can deliver 160% overload output for up to 200 ms, enabling stable startup of inductive loads such as motors, compressors, and water pumps.
3. Flexible Configurations & Multi-Source Integration
With two independent battery connections, system design becomes more flexible and scalable. The integrated smart port supports multiple energy sources—including grid-tied inverters, diesel generators, and wind turbines—making it ideal for hybrid micro-grid and multi-generation systems.
The system also features ultra-fast on/off-grid switching in under 10 ms, ensuring uninterrupted power during grid failures or transitions.
4. Scalable Parallel Architecture
For large-scale energy storage scenarios, the BESS-125K215 supports up to 10 units in parallel. For deployments of 6 units or more, the use of a power distribution cabinet is recommended to ensure optimal load management and system stability. This scalability makes the solution suitable for business parks, factories, data centers, commercial complexes, farms, and islanded micro-grids.
5. Certified for Global Compliance
The system meets international standards for safety and performance.
