Turnkey Single-Enclosure AC Storage Station
Integrates a 99.9 kW bidirectional PCS, 261 kWh liquid-cooled battery racks, HVAC, and fire protection in one outdoor unit.
Drop-In Commercial AC Retrofit
Connects directly to existing commercial 400 V electrical panels without modifying existing rooftop solar inverters.
99.9 kW Grid-Optimized AC Output
Pre-configured beneath standard 100 kW utility connection thresholds for streamlined connection approval.
Precision Liquid Cooling (≤2.5 °C)
Industrial coolant loop maintains uniform battery cell temperatures across extreme outdoor seasons.
More product details
Constructing separate indoor battery rooms, installing PCS units, and running complex inter-cabinet cabling requires months of engineering. The CM2-99.9K-261 integrates the PCS, battery racks, HVAC, and fire suppression in a single pad-mounted unit.
- Connects straight to the main commercial 400 V AC distribution panel with zero rooftop DC rewiring.
- Internal pre-wired bidirectional PCS manages power conversion at 97.5%+ European efficiency.
- Multi-sensor aerosol fire suppression, combustible gas detection, and emergency pressure relief vents.

Extending battery calendar life with active liquid thermal regulation.
Air-cooled commercial storage stations develop thermal hot spots during heavy summer peak shaving. The CM2 circulates liquid coolant directly through thermal plates beneath the 280 Ah cells. Circulating liquid coolant maintains cell temperature differentials strictly within ≤2.5 °C across the container. Extends battery calendar life by over 30% compared to conventional air-cooled commercial stations. Integrated HVAC maintains optimal 20–25 °C cell temperatures across extreme outdoor ambient conditions (-30 to +55 °C).
Same tank as CM2-125.
261 kWh / 832 V does not change on the power step. Current and PCS rating do.
