FAQ:
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 run a refrigerator or power tools?

Recommended load ≤80% of rated power. For inductive loads, use a pure sine wave model.

Is the cooling fan noisy during operation?

The noise is low (≤45 decibels, equivalent to normal conversation volume). The fan uses a silent motor and automatically adjusts the speed according to the device temperature (low-speed operation when temperature <40℃, high-speed operation when >60℃), balancing heat dissipation and noise.

What is the benefit of the UPS function? A2:

It automatically switches to battery power when AC fails.

 

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.
