Product details:<br><br> DC input: 12V DC input range: 10V-15V<br> No Load Current Draw: 1A<br> Efficiency:90%<br> AC output: 120V AC<br> Regulation:3%<br> Frequency: 60Hz<br> Socket:15A USA type<br> Low Voltage Alarm:9.5V-10.5V<br> Low Voltage Shut Down: 9V-10V<br> Over Load: shut off, recover manually<br> Over Voltage Shut Down:15.5V<br> Over Thermal: Shut Off Output Automatically, Over voltage protection<br> Cooling Ways: Cooling Fan will run when the temperature is over 50 degree<br> <br>Precautions: <br><br>1. Please use the standard battery cables we sent, or a full power output may not be guaranteed. And the spare fuses in the package are just used when the original ones are burned by accident.<br> 2. Please do not connect the inverter with the grid power, and a reverse connection of positive and negative is also forbidden.<br> 3. 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.<br> 4. 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.<br> 5. For a red light flashing, it is a kind reminder to note you the input voltage is a bit high, you can regardless of it. If the input is too high, the inverter will shut down automaticly.Please make sure your battery is fully charged before using.<br> 6. The output voltage can be adjusted in a little range.
