Suitable Applications

The SOK SK48V100N is designed for compatible 48V-class stationary energy storage applications, including home backup power, off-grid solar systems, battery banks, and rack-mounted energy storage installations. Its 5.12kWh capacity and 3U rack form factor make it suitable for systems where organized battery installation and inverter communication are required.

Inverter Communication

The battery provides CAN bus and RS485 communication for integration with compatible inverter systems. Supported communication depends on the inverter model, protocol selection, wiring, and system configuration. Confirm inverter compatibility and communication settings before commissioning the battery.

Bluetooth Monitoring

The built-in Bluetooth functionality provides access to available battery information through a compatible mobile application. Monitoring can be used to view battery operating information and system status without relying solely on the inverter display.

Battery Management & Protection

The integrated Smart BMS is designed to manage battery operating conditions and provide protection against conditions that may affect the battery. The battery also includes a pre-charge circuit intended to help reduce electrical stress when connecting to high-capacitance inverter systems.

Rack Installation

The SK48V100N uses a 3U rack-mountable design measuring 19.14 × 16.95 × 5.22 inches. The SPCC + SGCC enclosure has an IP20 rating, making the battery suitable for dry, protected indoor rack cabinets, server racks, utility rooms, and similar energy-storage environments.

Cold-Weather Operation

The built-in 100W heater is designed to support battery operation in cold conditions. Charging and discharging must remain within the specified temperature limits, and the complete installation should use charging equipment and settings compatible with the battery manufacturer's requirements.

Important Usage Note

Actual battery performance depends on inverter settings, connected loads, charging equipment, battery temperature, state of charge, wiring, and installation conditions. Use compatible LiFePO4 charging equipment and follow the manufacturer's voltage, current, communication, temperature, and protection requirements. Because the battery is IP20 rated, install it in a clean, dry, protected indoor location away from rain, standing water, and direct outdoor exposure.
