📌 Real-Life Project: 15MW / 15MWh Skid-Based Energy Storage
As a real-world implementation, the ENCAP Skid System was deployed in a 15MW project that serves as a model for utility-grade energy storage.
Project Specifications
- Project Scale: 15MW Power Capacity | 15MWh Energy Capacity
- Location Area: 31.4 meters × 21.3 meters
System Architecture:
- 3 ENCAP Skids deployed
- Each skid houses 12 ENVAULTs
- Total of 36 ENVAULTs used in the project
- Each ENVAULT contains 23 modules (18.2kWh each)
- Total Modules: 828
- Total Energy: 36 ENVAULTs × 418.6kWh = 15MWh
🏗️ Deployment Flexibility
This system was successfully installed within a 31.4m × 21.3m area (662.82 square meter) using modular skids, allowing for easy transportation, scalability, and plug-and-play deployment. Ideal for grid balancing, peak shaving, renewable storage, and remote/off-grid electrification.
Uncompromised Safety
- No fire or explosion risk – Encapsulated cell architecture
- Short circuit, over/under voltage, and current protection at both module and string levels
- Manual and automatic DC bypass systems for maintenance and protection
