Our company successfully delivered and commissioned an integrated photovoltaic and energy storage project in Romania, providing local customers with a mobile and scalable clean energy supply. The project utilizes four 10-foot, 46kW foldable photovoltaic containers and five grid-connected 100kW/215kW energy storage systems. These systems are integrated into the customer's existing EMS (Energy Management System), enabling truly intelligent scheduling and centralized operations and maintenance.
This project is located in an energy-scarce region of Romania, where the existing power grid often faces load pressure during peak hours. The customer required a renewable energy solution that is both independent and grid-compatible.
The system consists of the following components:
Four foldable photovoltaic containers
Each container is a standard 10-foot container and carries 92 500W high-efficiency monocrystalline silicon photovoltaic panels, generating a total power of 46kW. Integrated rollers and a tractor system enable rapid deployment and storage, making transportation and installation extremely convenient. High-protection combiner boxes and wiring accessories ensure safe and stable operation. Five 215KWh energy storage cabinets
Utilizing high-performance lithium iron phosphate cells, these units feature a dual-compartment, outdoor integrated design. Each unit has a capacity of 215KWh, with a total energy storage capacity exceeding 1,000KWh. Equipped with IP65 protection and a comprehensive temperature control system, they withstand harsh environments 24/7 and comply with European grid connection standards.
System Integration and EMS Integration
All equipment seamlessly connects to the customer's EMS platform via standardized interfaces. Compatible with communication protocols such as Modbus, CAN, and RS485, they enable remote real-time monitoring, load forecasting, and flexible scheduling.
Once completed, this integrated solar-storage system will demonstrate its value in multiple scenarios:
Emergency Response: Providing stable power support during post-disaster reconstruction and grid outages.
Temporary Event Power: Replacing traditional diesel generator sets at music festivals, outdoor exhibitions, large-scale events, and construction sites.
Energy Support: Ensuring continuous operations in remote areas such as oil and gas production areas and mining areas.
Mobile Leasing and Flexible Deployment: Meeting short-term power needs of enterprises and enabling resource sharing. By combining the flexible configuration of photovoltaics and energy storage, customers can dynamically allocate energy according to actual load conditions, while relying on EMS for remote management to ensure more efficient operation and maintenance and higher energy utilization.
Compared to traditional PV power plants, this project's "foldable + energy storage + EMS" model offers multiple advantages:
Quick Deployment
The foldable structure significantly reduces installation time, taking only a few hours from equipment arrival to commissioning. Standardized interfaces simplify on-site wiring and reduce construction complexity.
High Environmental Adaptability
The energy storage cabinets feature IP65 protection, making them dustproof and waterproof, easily surviving extreme outdoor conditions such as heat, humidity, and sandstorms, ensuring long-term stable operation.
Multi-Scenario Adaptability
Whether for emergency power supply, temporary events, or energy security in remote areas, the foldable PV container delivers rapid response, achieving true "plug-and-play" operation.
Intelligent Scheduling and Operations
After integration with the EMS, the system automatically schedules based on electricity prices, weather, and load forecasts, achieving peak load shifting and cost optimization while also improving battery life and system safety.
With the maturity of PV-storage integration technology, foldable PV containers are becoming a core solution in the distributed energy sector. They not only address transportation and installation challenges, but also, through integration with energy storage and EMS, form a flexible and replicable smart energy terminal. In the future, these systems will be more widely adopted in European and global markets, helping more industries achieve low-carbon transformation.
For companies seeking green energy solutions, this case demonstrates the feasibility and affordability of foldable photovoltaic containers and energy storage systems. If you're also interested in reducing energy costs while increasing energy independence, our company can provide customized solutions for different application scenarios and offer comprehensive support during project implementation and operations.
