233kWh 100kW Liquid Cooled Commercial Battery Energy Storage Cabinet for C&I Projects

100kW 233kWh Liquid Cooling C&I Energy Storage System

The 100kW 233kWh Liquid Cooling C&I Energy Storage System combines a 233kWh LiFePO4 battery with a 100kW rated PCS for commercial and industrial energy storage projects where energy duration is as important as power capacity.

The battery section operates at 832V nominal voltage with a specified 702–936V operating range. Liquid cooling is used for battery thermal management, while the system provides LAN, RS485 and CAN communication for project integration.

233kWh and 100kW Are Two Different Project Sizing Parameters

A commercial energy storage project should not be selected from battery capacity alone.

The 233kWh rating describes how much nominal energy is stored in the battery, while the 100kW PCS rating describes the rated power at which the system converts energy on the AC side.

How Long Can a 233kWh Battery Supply Different C&I Loads?

When project engineers evaluate an energy storage system, the expected discharge power has a direct impact on operating duration.

The examples below are simple nominal calculations using 233kWh of battery energy.

These figures are theoretical nominal comparisons rather than guaranteed discharge times. Actual operating duration will change with the control strategy, usable battery capacity, PCS efficiency and site load variation.

When Does 233kWh Make More Sense Than 215kWh?

The 215kWh and 233kWh configurations in this series both use a 100kW rated PCS according to the supplied parameter table.

The main reason to move to the 233kWh version is therefore additional stored energy rather than additional rated AC output.

If 100kW of rated power already meets the site's power requirement but the project needs additional discharge duration or more stored energy per cycle, the 233kWh configuration may be worth evaluating.

Use the Site Load Curve to Size the Energy Storage System

The most useful information for C&I BESS selection is often the site's actual load curve rather than a single peak power number.

A load profile shows how power demand changes throughout the operating day and helps determine both the required PCS power and the amount of battery energy needed.

100kW PCS for Commercial and Industrial Power Conversion

The PCS section is specified with 100kW rated output power and a maximum AC current of 167A.

Rated operating voltage is AC230/400V and the approved grid frequency range is 50/60Hz. AC harmonic voltage is specified at less than 3%.

The actual site connection, conductor sizing, electrical protection and grid interface should be designed according to the project requirements and applicable local regulations.

832V High-Voltage LiFePO4 Battery Architecture

The battery section uses LiFePO4 chemistry with a nominal capacity of 280Ah.

Nominal system voltage is 832V and the specified operating voltage range is 702V to 936V.

Nominal charging current and nominal discharging current are both listed at 140A.

These parameters form part of the DC-side system design and should be evaluated together with the PCS and complete project electrical architecture.

Liquid Cooling for Repeated C&I Charge and Discharge Operation

The supplied specification identifies liquid cooling as the battery cooling method.

Thermal management forms an important part of commercial and industrial battery operation because the battery may experience repeated charging and discharging according to the site's energy schedule.

The specified operating temperature range is -20°C to +60°C, while storage temperature is listed from -30°C to +45°C.

Site Planning for a 2.3-Ton C&I Energy Storage System

The system measures 1400 × 1000 × 2399mm and has an approximate net weight of 2.3 tonnes.

Before delivery, the project team should consider equipment access, installation space, foundation or supporting structure and maintenance clearance.

The supplied specification lists IP54 protection, operating relative humidity of 5% to 95% and a nominal working altitude of up to 2000m.

233kWh Is Not Automatically Better Than 215kWh

The larger battery capacity only provides value when the site actually needs the additional stored energy.

If the required 100kW discharge period is short enough that 215kWh already meets the energy target, the smaller configuration may be sufficient.

If the project requires more energy at the same 100kW PCS power level, the 233kWh configuration provides additional nominal duration.
