Welcome to my shop! Specification Output waveform : Pure sine wave Rated power: 3000W(please ensure that the rated power is higher than the rated power of the appliance you are using) Input DC voltage: 12V or 24V(Non-dual voltage input, please select the appropriate input voltage) DC voltage range: 9V-15.5V/19.5V-28V Output AC voltage: 230V AC voltage range: 220V-240V Low voltage alarm: 10V DC±0.5V Low voltage shutdown: 9V DC±0.5V Overload: shut down output Overvoltage shutdown: 15.5V USB output: 5 V - 2A Overheat : Automatic output shutdown Fuse : Short circuit Start-up : Soft start Digital display : Input/output voltage LED display Material : Aluminium alloy No load current : <2Amps Conversion efficiency : >90% Dimensions (approx.) : 390mm*180mm*140mm Weight (approx.) : 5.2KG Socket style : EU/Universal (commonly used in all countries' sockets, except 110V countries) AC socket: 2 sockets Colour: Blue Cooling Fans: When the temperature is less than or equal to 45℃,the fan stops working, and when the temperature is greater than or equal to 45℃, the fan starts to work. 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. 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. 4. Please do not connect the inverter to grid power and also prohibit the reverse connection of positive and negative terminals. 5. 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. Package includes. 1 x Inverter 1 x white wireless remote control (Batteries not included, 12V 23A batteries recommended) 1 x extra thick battery cable (1 x Battery thick cable 1 x Battery clip) 1 x User manual Troubleshooting 1. The inverter does not work. A. Check that the plug is in place and that it is not loose. B.Is the switch of the inverter turned on. C.Is there voltage output from the car lighter jack, if there is an external lead, is the polarity correct. 2. The output power of the inverter is not enough and can only drive small power appliances A. The capacity of the battery is too small and the appliance must be replaced or reduced. B. The battery voltage is too low and must be charged or replaced. C. If you change the car and the inverter is normal, you need to go to a professional repair shop to thicken the car cigarette lighter jack cable. The use of the cigarette lighter socket must not exceed a load of 150W. D. If it is an external battery, thicken the lead and shorten the lead length 3. The inverter does not work and the fault light goes out A. The electrical power used exceeds the rated power, causing protection. Reduce the use of electrical power B. The battery voltage is too low, the battery must be charged or replaced C. Reduce the use of electrical appliances
