1500V Liquid Cooled
Energy Storage Cabinet

MEGATRON 1500V 344kWh liquid-cooled and 340kWh air cooled energy storage battery cabinets are an integrated high energy density, long lasting, battery energy storage system.  Each battery cabinet includes an IP56 battery rack system, battery management system (BMS), fire suppression system (FSS), HVAC thermal management system and auxiliary distribution system.  Outdoor liquid cooled and air cooled cabinets can be paired together utilizing a high voltage/current battery combiner box.

Outdoor cabinets are manufactured to be a install ready and cost effective part of the total on-grid, hybrid, off-grid commercial/industrial or utility scale battery energy storage system.  BESS string setup examples are:

Battery Packs utilize 280Ah Lithium Iron Phosphate (LiFePO4) battery cells connected in series/parallel.  Liquid cooling is integrated into each battery pack and cabinet using a 50% ethylene glycol water solution cooling system.  Air cooling systems utilize a HVAC system to keep each cabinets operating temperature within optimal range. Aerosol fire suppression is also integrated into each outdoor cabinet allowing for safer and more controlled energy storage system design for firefighting.

340kWh rack systems can be paired with 1500V PCS inverters such as DELTA to complete fully functioning battery energy storage systems.
