SAJ CB2-57.3-HV5 battery module, 57.3 kWh

SAJ CB2 High-Voltage Battery System – Flexible Energy Storage for Commercial and Industrial Applications

The SAJ CB2 battery system has been specially developed for demanding commercial and industrial energy storage applications. Thanks to its modular design, the storage capacity can be flexibly adapted to the specific energy requirements. Depending on the configuration, capacities of 57.3 kWh, 71.6 kWh, 85.9 kWh or 100.3 kWh are available. The usable storage capacity is up to 90.2 kWh.

The battery is based on safe and durable LiFePO₄ technology with 280 Ah cells. A constant charge and discharge current of 150 A, as well as a discharge power of up to 50.1 kW, enable high performance even with demanding load profiles. Communication takes place via CAN, ensuring reliable integration with compatible SAJ inverters and energy management systems.

The floor-standing system has an IP55 protection rating and is designed for use at ambient temperatures ranging from –30 °C to +50 °C. The integrated climate control system ensures optimum battery temperatures and extends the service life of the storage cells. Thanks to its modular design, comprising individual 14.33 kWh battery modules, the system can be easily expanded or adapted to different project requirements.

The SAJ CB2 is ideally suited for applications such as:

• Optimising self-consumption in PV systems
• Peak shaving
• Load shifting (time-of-use)
• Commercial and industrial premises
• Agricultural businesses
• Supermarkets and manufacturing companies
• Emergency power supply and backup solutions in combination with compatible hybrid inverters
