Factory-integrated storage station with zero indoor space requirements.
Constructing fire-rated indoor battery switchrooms adds heavy construction costs and planning delays. The CB2-100.3 arrives as a fully integrated IP55 outdoor cabinet ready to connect to external concrete pads. Pre-wired with internal high-voltage DC busbars, motorized disconnect switchgear, and master BMS. Integrated HVAC unit maintains battery cells at an optimal 20–25 °C regardless of ambient weather. Automated aerosol fire suppression and gas detection provide certified industrial property safety.
