TWS Technology has reached another major milestone in global safety compliance. Our PowerCore Liquid-Cooling Container ESS has officially received IEC 62619, IEC 63056, and CE LVD certifications from the world-renowned audit body, TÜV Rheinland.
This achievement, celebrated at the 2025 SNEC, confirms that PowerCore meets the most rigorous safety and reliability standards required for the European market.
Multidimensional Safety: What These Standards Mean
We don’t just meet standards; we build a safety fortress around your energy investment. These certifications cover every stage of the product lifecycle:
IEC 62619 & 63056 (Battery & System Safety)
- These ensure total thermal stability and mechanical strength. From high-precision state-of-charge monitoring to intelligent cutoff mechanisms, these standards guarantee the system stays stable even under extreme conditions.
CE LVD (Electrical Reliability):
- This European Low Voltage Directive ensures the highest levels of insulation and grounding protection, effectively eliminating electrical hazards during operation.

PowerCore: High Efficiency, Maximum Safety
Since its 2025 launch, the PowerCore Container has set a new benchmark for utility-scale energy storage. It combines high-density 315Ah LFP cells with a modular design to deliver a superior return on investment.
Key Advantages:
- Massive Capacity: A standard 20-foot container delivers 5MWh of power.
- Cost Efficiency: Reduces the Levelized Cost of Electricity (LCOE) by over 40%.
- Flexible Deployment: The modular, side-by-side architecture allows for on-demand configuration for microgrids, utility plants, and renewable integration.
- Triple-Layer Fire Safety: Features early detection, targeted suppressant spraying, and an AI-driven big-data monitoring system to identify risks before they become hazards.
