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. Multi-sensor aerosol fire suppression, combustible gas detection, and emergency pressure relief vents.

SAJ CM2 99.9-125 kW / 261 kWh datasheet (EN)Product questions
What size AC breaker and cabling are required for this 125 kW station?
250 A 3-pole industrial MCCB; 95 mm² to 120 mm² copper cable. With a maximum continuous AC output current of 198.5 A per phase (at 400 V three-phase), install a 3-pole 250 A industrial circuit breaker (MCCB) on the main switchboard, paired with copper conductor cross-sections of 95 mm² to 120 mm².
Can multiple CM2-125K-261 units be installed in parallel?
Yes. Multi-unit parallel scaling for multi-megawatt-hour projects. Multiple CM2 outdoor stations can be connected in parallel on the same 400 V AC distribution bus, managed centrally by an SAJ eManager-C1 Pro controller to scale power and capacity to 500 kW / 1+ MWh.
