About WZRELB: Professional manufacturer for pure sine wave power inverter for 10 years, provide prompt reply, friendly customer service and 18-month . Product details: DC input: 12V DC input range: 10V-15V Efficiency: 85%-90% AC output: 120v Frequency: 60Hz Socket: Dual US type Low Voltage Alarm: 9. 5V-10. 5V Low Voltage Shut Down: 9V-10V Over Load: shut off, recover manually Over Voltage Shut Down: 15. 5V Cooling Ways: Cooling Fan will run when the temp is over 50 degree Celsius Precautions: 1. Please do not connect the inverter with the grid power, and a reverse connection of positive and negative is also forbidden. 2. Please do not overload. If your applications are inductive loads, please choose the inverters whose continuous power is 3-7 times higher than the watts of your appliances. If you want to power up a refrigerator, we suggest you use 10 times higher power inverter. 3. Please turn off the load first then turn off the inverter. And as there is a soft start function, please turn on the inverter first then turn on your loads, or the output may not stable at the first seconds. 4. For a red light flashing, it remind that the input voltage is a bit high. 5. Please use the set of standard battery cables we sent, or a full output may not be . There are build-in fuse for safety concern, the fuse come with package are just spare parts. 6. Considering transportation safety, we took off the battery of remote controller, you can buy it in your local place. Its specification is 23a 12v.

High quality pure copper inductance, filter the wave form, ensure the true pure sine wave AC output, safeguard your equipment. All big imported MOSFET with strong driving capacity. Wireless remote controller, can control the inverter within 100ft in room and 166ft in open area. Much more convenient for being used as car and home power supply. Build-in intelligent cooling fan works according to temp and not load. Prolongs battery life. It is fairly quiet and only cycles on when the temp is over 66 degree Celsius. Fully Safety Protections: Over voltage, Low voltage, Overload, Short circuit, Over heat, polarity reverse protection(fuse), Ground protection from leakage of electricity. WZRELB 3000W 12V DC to 120V AC pure sine wave inverter generator, as good as Grid power, 3000W continuous power, 6000W peak power, with LED displays for DC AC voltages. Dual us outlets.
