- Natural cooling — no active cooling required
- All-in-one: EMS/BMS, PLC, fire protection, HVAC
This datasheet defines our reference platform, not a boundary. Every storage system we deliver is sized and configured to the specific requirements of your project — energy capacity, inverter rating, container format, and integration scope are all determined in close collaboration with your engineering team. Our systems scale from 100 kWh to multiple MWh. Made to order means every system performs exactly as your grid, load profile, and site conditions demand.
