125 kW / 260 kWh Cabinet: Integrated PCS and nominal LFP storage in one liquid-cooled cabinet. This offer covers one cabinet.
Liquid Cooling: Working temperature range is -25 to 50°C, with derating below 10°C or above 40°C.
400 V AC Connection: Rated on-grid AC output voltage is 400 V at 50 Hz, with a maximum AC current of 181 A. Connection and backup layouts are project configuration items.
Single-String Battery Data: 702–936 Vdc and 98% depth of discharge; round-trip efficiency is >95% at 0.5C.
Cabinet dimensions for site planning
Listed dimensions are 950 × 1300 × 2480 mm (W × D × H), without the inverter; stated weight is 2.9 tons. The installed PCS footprint and site clearances belong in the project layout.
Optional expansion to six cabinet/PCS pairs
The Standard configuration is one 260 kWh cabinet with one 125 kW PCS. Optional configurations use two to six cabinets with the same number of PCS units. Six pairs provide 1560 kWh nominal capacity and 750 kW rated AC power.
IP55 cabinet with C3 corrosion rating
The specification lists IP55, C3 corrosion protection with C5 optional, and aerosol fire extinguishing. The fire protection configuration is to be specified for the order.
