Specification: Output Waveform : Modified Sine Wave Peak Output Power : 2000W(The maximum momentary power that can be generated by an appliance at start-up) Continues Output Power: 800W(please ensure that the rated power is higher than the rated power of the appliance you are using) Input DC Voltage : 12V（9V-15V）;24V（19V-30V） Output AC Voltage : 220V AC Voltage Range : 220V-240V Output Frequency : 50HZ Low Voltage Alarm : 12:10V DC±0.5V;24V:20 DC±0.5V Low Voltage Shut Down : 12V:9V DC±0.5V;24V:19 DC±0.5V Over Load : Shut Off Output Over Thermal : Shut Off Output Automatically Fuses : Short Circuit Start : Soft Start Material : Aluminum Alloy No load current : <2Amps Conversion Efficiency : >90% Sizes(Approximately) : 255*100*60MM Weight(Approximately) :1.2KG Socket Style: EU Color : Red What kind of electric load does Modified Sine Wave Inverter apply to? 1. It's applied to Non-Inductive Load such as Laptop,TV and so on. 2. If you want to use Inductive Load such as Refrigerator, High-power pump, Vacuum Cleaner, Drill and so on.You'd better to use a Pure Sine Wave Invetrer, otherwise the Modified Sine Wave Inverter may not work or break down. Fan's function: 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. Delivery Contents : 1 x Inverter 2 x alligator clip cables 1 x Cigarette lighter cables 1 x User Manual Troubleshooting 1.The inverter is not working. A.Check whether the plug is inserted in place and whether it is loose. B.Whether the inverter switch is turned on. C.Whether the car cigarette lighter jack has voltage output, such as external leads, and whether the polarity is correct. 2.Insufficient output power of the inverter can only drive low-power electrical appliances A.The capacity of the battery is too small, and electrical appliances must be replaced or reduced. B.The battery voltage is too low and must be charged or replaced. C.If you change to another car, the inverter is normal, and you need to go to a professional repair shop to thicken the car cigarette lighter jack cable. The use of the cigarette lighter socket shall not exceed a load of 150W. D.If it is an external battery, thicken the lead to shorten the lead length 3.The inverter does not work and the FAULT light is off A.The electrical power used exceeds the nominal 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 power appliances
