•  Charge and store electricity when the mains power is normal, and quickly invert the power supply after a power outage to ensure •  continuous electricity consumption. 
•  Independent mains power and diesel generator interface, intelligent switching, stable and reliable power supply. 
•  Hospitals, base stations, remote factories and mines are essential for emergency power supply.
