Q&A
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.
How to connect the battery with the battery clip?
Connect the positive and negative poles of the battery clip to the positive and negative poles of the battery respectively, and ensure a firm connection.
Is it normal for the inverter to heat up when working?
It is normal for it to generate some heat when working. If the temperature is too high (e.g., hot to the touch), please stop using it and check if the load is overloaded.
How to install the battery terminal wire?
Connect the red terminal wire to the positive pole of the battery and the black terminal wire to the negative pole. Ensure the interface is firm and there is no short circuit when connecting.
