FAQ:
Can this inverter drive a 3P air conditioner and a refrigerator at the same time?

Yes. The rated power of a 3P air conditioner is about 2200W-2500W, and an ordinary double-door refrigerator is about 150W-300W, with a total power of about 2350W-2800W, which does not exceed the 3000W continuous power; and the peak 6000W can cope with the instantaneous startup impact of the air conditioner. When using, ensure the battery capacity is ≥200Ah (12V) to ensure battery life.

What appliances can this inverter support?

Rated 1500W, peak 3000W – supports most home appliances.

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.

Is it a pure sine wave or a modified sine wave? What's the difference?

This is a modified sine wave inverter, suitable for most conventional home appliances and electronic devices; pure sine wave is suitable for precision devices with extremely high power requirements. This modified sine wave is more cost-effective at 2000W, meeting the needs of most scenarios.
