FAQ:
How does the UPS function of this inverter work?

When the external power supply is normal, the inverter powers the device while charging the battery; when the external power supply is interrupted, it automatically switches to battery power to ensure uninterrupted operation of the device.

Does it only support DC12V input voltage?

The regular model has DC12V input, and other input voltages such as DC24V can be customized. Please consult customer service for details.

Can it be used in RVs or trucks?

Yes. The device input voltage is DC 12V, which matches the battery voltage of RVs and trucks. It can be connected via battery clips or cigarette lighter interface (need to confirm that the maximum current of the cigarette lighter is ≥10A) to supply power to car refrigerators, parking air conditioners, laptops, etc.

Can this inverter power a laptop?

 If the laptop power is within 150W and the input is AC220V, it can supply power normally.

What is the difference between labeled 6000W and full power 3000W?

Labeled 6000W is peak power, which is only used to cope with the instantaneous high-power demand during device startup (such as air conditioner, motor startup); full power 3000W is continuous power, referring to the power that the device can stably output for a long time. When driving appliances daily, 3000W should be used as a reference to avoid total power overload.
