Output waveform: Pure sine wave Don't connect the inverter to the household circuit! When using 12V/24V to connect the cigarette lighter wire in the car, please do not exceed 120W. Otherwise the car fuse will blow! The installation and commissioning of the inverter should be carried out by electrical maintenance personnel who understand the structure and operation of the inverter. 12V's inverter only can link 12V's battery (Normal operating range is from 9V to 15.5V) and 24V's inverter only can link 24V's battery (Normal operating range is from 19.5V to 28.5V)
