100kW 215kWh Liquid Cooling Commercial Energy Storage System for Hybrid PV-Storage-Diesel Applications
100kW 215kWh Solar Diesel Hybrid Commercial Energy Storage System.
This liquid cooled commercial energy storage system combines a 215kWh LiFePO4 battery platform with support for grid-connected and off-grid power conversion, photovoltaic input and diesel generator linkage. The configuration is designed for commercial and industrial energy projects where several energy sources need to operate within one power system.
PV, Battery and Diesel Generator in One Hybrid Power Architecture
Unlike a battery system used only for grid-connected energy storage, this configuration provides parameters for photovoltaic input, battery storage, grid operation, off-grid operation and diesel generator connection.
This makes it relevant to C&I projects where solar generation, stored battery energy, utility power and diesel generation may all form part of the overall power architecture.
Grid and Off-Grid Power Conversion
The optional PCS specification includes both grid-connected and off-grid operating parameters. On the grid side, rated output power is 100kW with AC 380/400V operation at 50/60Hz. For off-grid operation, the specified output voltage options are 220V, 230V, 380V and 400V.

Liquid Cooling for the 215kWh Battery Platform
The battery section uses LiFePO4 chemistry with a nominal voltage of 768V and a specified operating voltage range of 648V to 864V. Both nominal charging and discharging current are rated at 140A.
Liquid cooling is specified as the battery cooling method. The technical data lists 8,000 cycles and a calendar life of 15 years.
Frequently Asked Questions
Does this 215kWh energy storage system support both on-grid and off-grid operation?
Yes. The optional PCS parameters include separate specifications for grid-connected and off-grid operation, both with 100kW rated output power.
Can a diesel generator be connected to the energy storage system?
Yes. Diesel generator linkage is specifically listed in the technical specification.
Can the system accept solar PV input?
Yes. The specification includes photovoltaic input parameters and lists a maximum PV power of 156kW for two channels.
What is the grid-to-off-grid switching time?
The specified STS handover time is 20ms.
Is the PCS included as standard?
The technical parameter sheet lists the PCS as optional. The final supplied configuration should therefore be confirmed according to the project requirement and quotation.
What AC voltage does the system support?
For grid-connected operation, the specification lists AC 380/400V at 50/60Hz. For off-grid operation, the listed voltage options are 220V, 230V, 380V and 400V.
Can several systems operate in parallel?
The parameter sheet specifies up to three units for grid-connected/off-grid parallel operation.
What communication interfaces are available?
The listed communication interfaces are LAN, RS485 and CAN.
Discuss Your Hybrid Energy Storage Configuration
For a PV-storage-diesel project, provide the required battery capacity, load power, grid voltage, solar PV capacity, operating mode and diesel generator information. The final PCS and system configuration can then be confirmed according to the project requirements.
