The BOS-A series are modular LiFePO4 (LFP) energy storage units designed for building scalable high-voltage (HV) systems for homes and small businesses. The applied LFP chemistry stands out for its high thermal safety level and stable performance during daily cycling, which in practice translates to a longer lifespan and lower degradation risk compared to NMC-based solutions. Each module operates within a rack configuration, and the intelligent BMS automatically monitors charging and discharging, balances cells, and protects against overloading and extreme temperatures.

The BOS-A is designed as a scalable system - you can add more modules as energy consumption, PV system capacity, or backup power needs increase. CAN communication facilitates seamless integration with hybrid inverters and on-grid or off-grid systems, where smooth mode switching is essential. The rated cycle life and 10-year warranty ensure predictable energy costs over the long term - both for prosumers and businesses.
