Product Description

To ensure plug-and-play functionality, a 20GP integrated solution typically includes the following key components:
LFP (Lithium Iron Phosphate) battery rack: High cycle life, safe and stable.
PCS (Power Conversion System) or Hybrid Inverter: Enables AC/DC conversion.
BMS (Battery Management System): Monitors battery status and prevents overcharging and over-discharging.
EMS (Energy Management System): The core of the control strategy.
Temperature control system: Industrial-grade air conditioning to ensure constant cell temperature.
Fire suppression system: Automatic fire suppression system using aerosol.
Power distribution cabinet: Internal power distribution.

-Highly Adaptable – Reliable operation in extreme temperatures up to 50°C
-More Secure – Modular fire protection system with safety isolation partitions inside the engine room
-Flexible Deployment – Scalable architecture for easy capacity expansion
-Long Lifespan – Design life exceeding 15 years
-Ideal for utility-scale, C&I, and microgrid applications where reliability and ROI matter most.
Questions&Answers
Q1: In which scenarios are 20GP containerized energy storage systems primarily used?
A: Due to its moderate size and strong scalability, the 20GP system is ideally suited for:
-Commercial and industrial users: Peak shaving and valley filling, reducing electricity costs for industrial parks or shopping malls.
-Integrated photovoltaic, energy storage, and charging systems: Working in conjunction with chargers and solar to mitigate the impact of charging stations on the power grid.
-Microgrids: Providing independent power sources for islands, remote mining areas, or areas without electricity.
Renewable energy generation: Smoothing output fluctuations from solar power plants or wind farms.
Q2. Can the system operate stably in extreme high or low temperature environments?
A: Yes. The 20GP container is equipped with an industrial-grade thermal management system.
Built-in air conditioning and insulation ensure that the battery always operates within its optimal temperature range (typically 15°C-25°C) in environments ranging from -20°C to 50°C,
thus guaranteeing battery life and charge/discharge efficiency unaffected by extreme weather conditions.
Q3. Compared to building traditional fixed energy storage facilities, what are the advantages of containerized energy storage systems?
A: They offer three major advantages: high integration, high mobility, and low cost.
Traditional infrastructure requires on-site construction, which is time-consuming and immobile;
while 20GP containerized energy storage, as a standardized plug-and-play unit, not only significantly reduces on-site civil engineering costs, but also allows for complete relocation to a new location after project completion, resulting in higher asset utilization.
