SAJ CB2-71.6-HV5 (71.6 kWh C&I battery cabinet)
Description
Low-current long-string transmission for heavy commercial cycling.
SAJ CB2-85.9-HV5 is an 85.9 kWh pre-integrated commercial outdoor battery cabinet operating at 921.6 V nominal, equipped with eighteen 50 A BU2-HV5 modules, active HVAC climate control, and aerosol fire protection for heavy industrial energy storage.
921.6 V High-Voltage Operating Bus (18 Modules)
High operating voltage minimizes DC transmission losses when paired with 75–125 kW commercial hybrid inverters.
Pre-Integrated Turnkey Outdoor Cabinet
Factory-installed master BMS, motorized DC switchgear, and internal busbars eliminate on-site wiring delays.
Integrated HVAC Air Conditioning & Heating
Maintains optimal battery cell temperatures across extreme outdoor seasons (-20 °C to +50 °C).
Multi-Tier Aerosol Fire Protection
Automated thermal sensors and integrated fire suppression provide commercial property safety.
