A 100kWh system typically consists of 280Ah LFP cells arranged in series-parallel configurations (e.g., 1P32S per module, multiple modules in parallel), integrated with a BMS, air-cooled cabinet, PCS inverter, and EMS. It delivers stable DC output and supports AC-coupling for grid interaction.
The system uses high-efficiency axial or centrifugal fans to drive airflow across cell surfaces. Paired with temperature sensors and smart controllers, the cooling system dynamically adjusts fan speed to maintain safe thermal conditions and extend battery life.
The system includes BMS-level protections (overvoltage, undervoltage, overcurrent, overtemperature), EMS alarms, airflow fault detection, smoke sensors, and optional aerosol fire suppression. The cabinet design follows IEC and UL standards.
The system is typically housed in an IP54-rated outdoor cabinet or indoor rack with footprint around 1.5–2.5 m². It requires proper ventilation space, ambient temperature control (recommended 0–35°C), and stable concrete foundation or platform.
Ideal for industrial peak shaving, commercial load shifting, PV-storage hybrid systems, telecom base stations, data centers, and EV charging stations. Air cooling is particularly suited for moderate environments with stable ambient conditions.
With ≥6000 cycles and proper thermal management, the system lifespan is 10–15 years. Highjoule provides 5–10 year product warranties and optional O&M packages, ensuring long-term reliability and performance.
Highjoule’s HJ-G20-100F and HJ-G50-100F industrial energy storage systems (100kWh, LFP 3.2V/280Ah) are ideal for factories, microgrids, and renewable integration.
