Designed for high-power marine applications, the High-Power Marine ESS Container delivers up to 1.2 MW of continuous output, providing reliable backup power for vessels during generator outages or peak load conditions. With a 2.5 MWh energy capacity, the system is optimized to supply high-power loads for short-duration operations while ensuring stable and uninterrupted power delivery.
Built in a 20-foot containerized solution, the system integrates high-performance LFP battery modules, an advanced Battery Management System (BMS), thermal management, fire protection, and marine-grade safety features. Its compact, modular design enables easy transportation, installation, and maintenance in demanding offshore environments.
Ideal for dynamic positioning (DP) vessels, offshore construction ships, heavy-lift cranes, and other marine applications requiring rapid, high-power energy support, the container enhances operational reliability, reduces generator dependency, and contributes to lower fuel consumption and emissions.
