5MWh Liquid-cooling Energy Storage Container

Superb safety: triple fire protection measures guarantee early detection, accurate spraying, and rapid fire suppression throughout the entire process; big data intelligent fire monitoring system features panoramic surveillance and fire risk warning, risks spotted in advance, and rapid response taken across the system.
High economic efficiency: 315 Ah LFP cells with high energy density and prolonged cycle life realizes a cost reduction per kWh of 30%; 5MWh in one 20ft container; side-by-side arrangement; saving over 40% of the project area.
Increasing flexibility: flexible system topology for various scenarios, including the power generation side, grid side, and user side; modular design enables flexible capacity and configuration.
