Specifications: DC input: 12V(10V-15V) AC output: 120VDC No Load Current Draw: 0.8A Efficiency: 90% Frequency: 60Hz Socket: Dual USA Outlets Low Voltage Alarm:9.5V-10.5V Low Voltage Shut Down: 10V-11V Over Voltage Shut Down: 15.5V Cooling Way: Cooling Fan, will run until the temperature is above 50 Degrees Celsius Working Temperature: Minus 10 Degrees Celsius to 50 Degrees Celsius Storage Temperature: Minus 30 Degrees Celsius to 70 Degrees Celsius Total Harmonic Distortion: less than 5% Precautions for resistive load applications and inductive load applications: If you need the inverter to run the resistive load (like TV, electric cooker, LED light), please choose the inverter with continuous power higher than the appliance's rated power. For example, for the power inverter with continuous power 2500w, it is suggested to run the appliance with rated power less than 2500w. It is best to use 80% of the rated power. If you need the inverter to run the inductive load (for an appliance such as a compressor, motor, water pump), please calculate the power of inverter 3 to 7 times higher than the rated power of your appliance.
