CATL LFP cells and a three-level BMS support industrial operation. Liquid cooling helps maintain consistent cell temperatures.
- 280 Ah cells; seven modules of 52 cells each
- Maximum battery C-rate: 0.5 C
- IP55 for suitable outdoor installation
- HIS Energy Manager and HIS EnergyFlow
- Ethernet and Modbus RS485
The cycle rating follows battery datasheet conditions. Final system design and power limits are confirmed per project.
Dimensions and technical documentation
- Dimensions: 1,350 × 1,300 × 2,260 mm
- Weight: approximately 3,150 kg
- Operating temperature: −20 °C to +55 °C
- Technical documentation lists IEC 62619 and IEC 62477-1:2012, with UL9540A at cell level
Request the applicable reports for the offered configuration. Cell-level testing does not establish certification of an entire site installation.
Industrial applications and expansion
Assess peak shaving, PV integration and flexible strategies in 600 V or 660 V production facilities. Repowering can include a review of existing battery, PCS and EMS interfaces. Multiple 326 kWh units can be considered when energy and power requirements grow.
Select another architecture for 690 V or 800 V
The 326L is not offered indiscriminately for every voltage. For 690 V projects, HIS considers Sinexcel architectures with 418 kWh cabinets or an approximately 5.016 MWh container. The PowerPack 800V is the dedicated route for suitable 800 V infrastructure.
Questions about this BESS solution
Can the HISbatt 326L connect directly to 690 V?
The current configuration described here is for 600 V or 660 V with a 137 kW KACO PCS. A 690 V installation needs a separately approved architecture.
What information is needed for a 326L assessment?
Share the connection voltage, single-line diagram, transformer data, load profile and intended application where available. Target kW and kWh are optional for the initial enquiry.
Can several 326L cabinets form a larger plant?
Multiple cabinets can be considered after checking the combined battery and PCS design, protection, communications, grid capacity and operating strategy.
