Containerized 3.7MWH / 5MWH BESS: Grid-Scale Battery Storage for Utility Solar Energy Projects
3.7MWh 5MWh containerized BESS is a factory-integrated, liquid-cooled energy storage solution designed for solar-plus-storage, microgrid, and grid support projects. The system is offered in two energy configurations—3.7MWh and 5MWh—to match different discharge duration and dispatch requirements. Inside the container, battery racks, liquid cooling thermal management, BMS, and monitoring interfaces are integrated for fast site deployment and simplified commissioning.
System Overview: Built for Scale and Performance
This containerized BESS is offered in two energy configurations (3.7MWh and 5MWh). It integrates battery racks, liquid-cooling thermal management, BMS, and EMS communication interfaces inside a standard container enclosure. PCS power rating (MW) can be selected to match the target discharge duration and grid requirements.

Built for Utility Scale Solar Energy Projects
This BESS is designed from the ground up to complement and enhance solar energy plants, including:
- Grid-tied solar power plants
- Renewable solar energy farms
- Hybrid generation sites (solar + wind + storage)
- Community and municipal solar grids
Why Liquid Cooling
Liquid cooling improves temperature uniformity across battery racks, helping the system maintain stable performance under high ambient temperatures and heavy cycling profiles. A well-managed thermal profile contributes to improved lifecycle consistency and reduces the risk of cell imbalance or thermal hotspots—especially for containerized deployments with high energy density.
Safety & Protection
Safety is central to the container design and control logic. The BMS provides monitoring and protection functions such as over/under-voltage, over-current, temperature protection, and alarm management. Optional safety integrations can be configured based on project requirements, including fire detection, gas sensors, ventilation strategy, and suppression options. (Final configuration should follow the target market standards and site code requirements.)
Typical Use Cases
3.7MWh 5MWh containerized BESS is commonly deployed in:
-
Solar PV + Storage: reduce curtailment and shift PV generation to evening peak demand
-
C&I Peak Shaving / TOU Arbitrage: reduce demand charges and optimize energy cost
-
Microgrid / PV-Diesel-BESS Hybrid: improve fuel efficiency and stabilize power quality
-
Grid Support (where allowed): ramp-rate control, frequency/voltage support, and dispatch-based services depending on grid code
How to Select 3.7MWh vs 5MWh
Choose 3.7MWh when the project prioritizes shorter-duration dispatch, smaller interconnection limits, or pilot-stage deployment. Choose 5MWh when longer-duration time shifting, higher usable energy, or improved dispatch value is required. The PCS MW rating directly affects discharge duration (hours), so the optimal combination depends on your target application and operating profile.
