215kWh 100kW Liquid Cooling Hybrid C&I Energy Storage System for Solar Diesel Projects

215kWh 100kW Hybrid C&I Energy Storage for Solar Diesel Systems

The 215kWh 100kW Hybrid C&I Energy Storage for Solar Diesel Systems is designed for commercial and industrial projects that need to coordinate battery storage with solar PV, the utility grid and diesel generation.

The system combines 215kWh of LiFePO4 battery energy with a 100kW PCS, liquid cooling, grid-connected and off-grid operation, PV input capability and diesel generator linkage.

One C&I Energy System, Four Possible Power Sources

Many commercial sites do not operate from a single energy source. A facility may have utility power, rooftop or ground-mounted solar PV, battery storage and an existing diesel generator.

In this type of project, the key question is not simply how much battery capacity is installed. It is how the different power sources are coordinated according to site demand and operating conditions.

Why Add Battery Storage to a Solar and Diesel Power System?

A diesel generator and a battery energy storage system perform different roles.

The generator produces energy from fuel when required, while the battery stores electrical energy for later use. Combining different power sources gives the project designer more options for deciding when each source should operate.

The final operating strategy depends on the site load curve, grid availability, PV generation profile, generator rating and required power continuity.

20ms STS Handover for Power-Source Transition

The supplied parameter sheet lists an STS handover time of 20ms.

This specification is relevant to projects where the system needs to transition between operating states or power sources.

Whether a particular load can tolerate a 20ms transition must still be checked according to the load type and the site's electrical requirements.

100kW Grid-Connected and Off-Grid PCS Operation

The PCS section specifies 100kW rated output power for both grid-connected and off-grid operation.

For grid-connected operation, rated AC voltage is 380/400V at 50/60Hz. The rated AC current is listed as 167A / 159A.

For off-grid operation, the supported rated operating voltages are listed as 220V, 230V, 380V and 400V, with a maximum output power of 100kW.

The final voltage configuration should be confirmed according to the electrical system at the project site.

156kW PV Input for Solar-Storage Projects

The PV section of the supplied specification lists a maximum power of 156kW across two PV channels.

The PV starting voltage is listed at 195V, with an MPPT operating range of 180V to 800V.

This allows the BESS to be evaluated for commercial solar-storage projects where PV generation forms part of the total site energy strategy.

215kWh Battery Energy with a 768V LiFePO4 Platform

The battery section uses LiFePO4 chemistry with 215kWh total capacity, 280Ah nominal capacity and a nominal system voltage of 768V.

The specified operating voltage range is 648V to 864V. Nominal charging current and nominal discharge current are both listed at 140A.

Cycle life is specified at 8000 cycles and calendar life at 15 years according to the supplied parameter sheet.

Liquid Cooling for Commercial Battery Operation

The battery thermal management system uses liquid cooling.

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

Operating relative humidity is specified from 5% to 95%, with a nominal working altitude of up to 2000m and an IP54 enclosure rating.

Project Deployment Requires More Than Electrical Sizing

The current product specification lists cabinet dimensions of 1385 × 910 × 2203mm and an approximate net weight of 2.2 tonnes.

For an EPC or project contractor, this means procurement planning should also include transportation, unloading, lifting, installation access, equipment foundation and future service clearance.

When Is a Solar-Storage-Diesel Architecture Worth Evaluating?

A hybrid energy architecture can be relevant when a commercial or industrial site depends on more than one power source.

Instead of asking only whether the site needs 215kWh of battery capacity, the project team should evaluate the complete energy flow throughout the day.

Parallel Expansion for Larger C&I Projects

The supplied parameter sheet lists up to three grid-connected or off-grid parallel machines.

Parallel system design should be confirmed according to total PCS power, battery architecture, AC distribution, control strategy and the actual project requirements.
