Features & Advantages

Intelligent Liquid Cooling

Closed-loop thermal management maintains cell ΔT < 3°C uniformity across all clusters. Reduces auxiliary power by up to 40% vs. air-cooled. IP66-rated battery modules ensure protection in extreme humidity environments.

3-Level Safety Architecture

Pack-level thermal runaway detection with multi-stage BMS, three-level explosion-proof design, aerosol suppression + water fire protection (optional). <20 ms PCS response for primary frequency regulation.

Plug-and-Play Deployment

Factory-prefabricated 20 ft ISO container — all systems tested before shipment. Energy density >80% higher than air-cooled equivalents — minimises site footprint and commissioning time.

Cloud EMS · Regional Service

AI diagnostic dispatch, OTA upgrades, remote fault diagnostics. Service centres in Europe, Africa, East Asia and Central Asia — spare parts stocked in-region for rapid response without factory lead times.
