SOFAR PowerMagic Battery Cabinet 258 kWh is a high-voltage battery cabinet designed to operate as an element of the modular PowerMagic energy storage system for commercial and industrial applications. The unit is used to expand the energy capacity of an energy storage system and works together with the Energy Storage Cabinet , which contains the inverter (PCS), EMS system and AC connection components.

The Battery Cabinet is not a standalone energy storage system – it represents the battery section of an ESS/BESS system, responsible solely for storing electrical energy.

The cabinet is equipped with lithium iron phosphate (LiFePO₄ / LFP) battery cells, providing a high level of safety, long service life and resistance to intensive operation. The integrated BMS monitors battery operating parameters and communicates with the higher-level PowerMagic control system.

Key technical parameters:

• Nominal capacity: 258 kWh
• Usable capacity: 258 kWh
• Battery technology: LiFePO₄ (LFP)
• Nominal voltage: approx. 768 V DC
• DC voltage range: 734.4 – 1036.8 V
• Battery management system: integrated BMS (cooperation with PowerMagic EMS)
• Cooling: active liquid cooling
• Safety: multi-level protection at cell, module and cabinet level
• Enclosure protection rating: IP55
• Operating temperature range: –30°C to +60°C
• Dimensions (W × D × H): approx. 1000 × 1350 × 2200 mm
• Weight: approx. 2500 kg

Key features and benefits:

• Modular design enabling parallel connection of multiple Battery Cabinets
• Expansion of energy storage capacity without increasing system power
• High safety level thanks to LFP technology and liquid cooling
