The customers’ enjoyable purchasing experience is rather important for us. If something goes wrong with your product, please do not hesitate to contact us for assistance. 2.if any issues came out during the warranty, please send us the video which show how inverter fail to work normally, and your order . Our specialist will find out the reason accroding to your video.We will send the replacement or others to solve the problem noteHow to choose a Proper Inverter? There are two types of Inverter, one being a modified sine wave inverter, the other a pure sine wave type.For Inductive Load If connecting with inductive loads (e.g. Microwave, coffee machine, k7 karcher power washer, Compressor, Water Pump, Saw, Drill, old CRT TV, Refrigerator, Ice conditioner, Air conditioner, Relays，Fluorescent lamp, Vacuum cleaner, smoke machine, Sound system,random orbit sander, orbital polisher), please choose a PURE SINE WAVE inverter whose rate power is 3-7 times higher than the load's rate power. For example, for a 150w refrigerator(7 times), please choose a 1500w Pure Sine Wave inverter or higher; for a 800w air conditioner, please choose 2500w Pure Sine Wave inverter or higher. For Resistive Load If connecting with resistive loads (e.g. Kettle, Toaster, Shower, Computer, TV, Fan, Scanner, Fax machine, Duplicator, Juice extractor, Heater, Electric cooker, crock pot), please choose either modified sine wave or pure sine wave inverter whose continuous power is a little higher than the load's rate power. For example, for loads near 700w, it's better to choose inverter with continuous power more than 800w. Battery Recommended Tips: Before you connect your devices, think about the battery capacity you need. A small battery cannot run a high wattage device. For example, if you run an 800W heater for 2 hours, how many AH batteries should be used? Take a 12V battery as an example: Rated wattage 800w/conversion efficiency of inverter (calculated at the lowest 85%)/battery voltage (12V/24V)/battery discharge coefficient 80%*working time (2 hours) =800W/85%/12V/0.8*2H=196AHMaximum wattage of devicesDC voltBattery RecommendedRunning Time3500W12V/24V400AH/200AH1h 00min3000W12V/24V360AH/180AH1h 03min2500W12V/24V300AH/150AH1h 03min2000W12V/24V240AH/120AH1h 03min1500W12V/24V200AH/100AH1h 10min1200W12V/24V120AH/60AH0h 53min850W12V/24V100AH/50AH1h 02min600W12V/24V80AH/40AH1h 10minCooling fanRun all the timeColorredTypeModified Sine Wave InvertermaterailaluminumFeaturesDC/AC, High Voltage Input Protection, Low Voltage Input Protection, On/Off Switch, Overheating Protection, Short Circuit ProtectionRMS Power500WInput Voltage12VMPN500WOutput Voltage110VBrandLvyuanSystem ConfigurationOff-GridVoltageDC 12V TO AC 110V/120VCurrent TypeAC/DCCharging ModeNONCurrent OutputNONApplicationAutomotive, Camping/Hiking, Commercial, Electronics, Home/GardenResistance PropertiesAbrasion ResistantPower500W ratedModelF-500UCurrent RatingNONWattage500WMaterialaluminumPower SourceBATTERYRecommended EnvironmentIndoor/OutdoorSize4.92inch*3.07inch*1.80inchnot fitpower tools /battery charger
