Containerized Battery Solar Power Storage Plants
Containerized Battery Solar Power Storage Plants

1mW/2mWh Containerized Battery Solar Power Storage Plants are suitable for use in public buildings, communities, medium and large enterprises, utility-scale storage systems, off-grid systems, electric vehicles and backup systems. The storage system's container allows you to store energy generated through a wind turbine, photovoltaic, or CHP. Because of their long lifetime, the storage containers can also be used for peak shaving, thus reducing power bills.

Frequently Asked Questions

What is the typical capacity of a containerized BESS?
The system shown is a 1000kW/2150kWh unit, but the modular design allows for customization according to specific energy needs, ranging from smaller 215kWh units to multi-megawatt utility-scale plants.
What types of batteries are used in these storage systems?
The system primarily utilizes Lithium Iron Phosphate (LFP) cells, known for their safety and long cycle life, but it can also be adapted for lead-acid or direct MPPT solar panel integration.
How is the temperature regulated inside the container?
The container features an intelligent cooling system. Depending on the environment and requirements, it uses industrial air conditioning for the battery compartment and intelligent air cooling for the electrical compartment.
What are the main applications for 1mW/2mWh storage?
It is ideal for peak shaving (reducing power bills), backup power for enterprises, grid frequency regulation, integration with renewable energy sources like wind or solar, and electric vehicle charging stations.
Is the system compatible with local power grids?
Yes, the systems are designed to comply with international standards (CE, CSA, TUV) and can be configured to meet local grid-tied policies and usage requirements globally.
How is the battery system monitored?
The system utilizes a sophisticated three-layer architecture consisting of BMU, BMS, and MBMS, which communicates via RS485, CAN, or Ethernet to provide real-time state monitoring and parameter adjustment.
