Gotion Smart Storage 7MWh, 4 hours (first delivery to Greece January 2027)

The ultimate liquid-cooled storage system (ESD1331-025P7044)

Gotion 7MWh Container

The **Gotion Smart Storage 7MWh** represents the future of large-scale BESS. With a nominal capacity of **7,044 kWh**, it is one of the world's most energy-dense storage solutions within a standard 20-foot container. Integrating state-of-the-art liquid-cooling technology and fully certified to the strictest European standards (CE), it offers the highest return on investment for utility-scale projects with limited available space.

Leading energy density

Achieves over 7MWh of capacity in a standard 20ft container footprint, drastically reducing land costs, civil engineering requirements, and overall project Capex.

Advanced thermal stability

The optimized liquid-cooling system guarantees a temperature difference between cells of ≤2.5°C, ensuring uniform battery aging and maximum service life.

Level 4 safety

Designed for absolute safety, featuring multi-gas detection sensors, active venting, and a triple-action fire suppression system (Pack-level, Compartment-level, Water-firefighting).

CE certified quality

Fully compliant with European safety and operational standards, the 7MWh system is ready for immediate permitting and grid connection across the EU.
