Welcome to my shop! Specification Output waveform. Pure sine wave Rated power: 4000W (please ensure that the rated power is higher than the rated power of the appliance you are using) Input DC voltage: 12V or 24V Please select the appropriate input voltage for you DC voltage range: 9V-15.5V/19.5V-28V Output AC voltage: 220V AC voltage range: 220V-240V Low input DC voltage (DC) : Turn off (9V5%) ;Turn off (19V5%) High input DC voltage (DC) : Turn off (15V5%) ;Turn off (30V5%) Overload: shut down output Overvoltage shutdown: 15.5V Overheat : Automatic output shutdown Fuse : Short circuit Start-up : Soft start Digital display : Input/output voltage LED display Material : Aluminium alloy No load current : 90% Dimensions (approx.) : 450mm*180mm*140mm Weight (approx.) : 6-6.3KG Socket style : EU AC Socket: 2 Sockets USB output:5V-2A Colour: Blue/Black Cooling Fans: When the inverter is turned on, the fan works immediately and its working sound will be a little louder than that of a pure sine wave inverter. So if noise is a concern, please order a pure sine wave inverter. 8 Safety protection features High voltage input cut-off protection. Low voltage alarm protection. Overload protection. Overcurrent protection. Surge power protection. Reverse connection protection. Short-circuit protection from fuses. High quality is always a fundamental principle for inverters. Package includes. 1 x Inverter 1 x white wireless remote control (Batteries not included, 12V 23A batteries recommended) 4 x extra thick battery cable 1 x User manual Please note. 1. Make sure that the rated wattage is higher than the appliance you want to use. 2. If you want to run several appliances at the same time, you should refer to the total wattage. 3. Please use the standard battery cables we send you, otherwise full power output may not be guaranteed. And the spare fuse in the package is only for use in case the original fuse is accidentally blown. 4. Please do not connect the inverter to grid power and also prohibit the reverse connection of positive and negative terminals. 5. Please do not overload. If your application is an inductive load, choose an inverter with a continuous power 3-7 times higher than the wattage of your appliance. For example, refrigerators, freezers, drills, washing machines, water pumps, microwave ovens, ovens, hoovers, hair dryers, etc. with motors inside.
