FAQ

Pure Sine Wave Inverters

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.

Modified Sine Wave Inverters

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 working principle of the UPS function?

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

Is customization available?

OEM/ODM support for logo, color, and packaging design.

Distributor

Do I need to carry inventory?

We offer flexible inventory options based on your market needs, and we can assist with supply chain management.
