Q&A
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.
Can this inverter power a laptop?
If the laptop power is within 150W and the input is AC220V, it can supply power normally.
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 to the battery?
Use the included battery clips, connect the red clip to the positive pole of the battery and the black clip to the negative pole. Ensure good contact and no short-circuit risk when connecting.

Congsin 3000W LCD Pure Sine Wave Inverter for Home Use Solar Backup Power Inverter Off Grid UPS
3000W Full-Power Pure Sine Wave Inverter (Labeled 6000W), DC 12V to AC 220V Power Converter, Suitable for High-Power Devices
This pure sine wave inverter (Model: CS3000PSW-L6000) features "3000W full continuous power output + labeled 6000W peak power." Adopting pure sine wave output technology (waveform distortion rate <2%), its power quality is close to mains power, which can safely drive high-power precision devices such as air conditioners, refrigerators, electric tools, and medical instruments, avoiding equipment malfunctions caused by unstable waveforms. The device supports DC 12V input (compatible with 10.5V-14.8V wide voltage): 3000W continuous power meets long-term stable power supply, and 6000W peak power easily copes with the instantaneous startup impact of devices. Equipped with 4 AC universal sockets (16A) and 2 USB 3.0 fast-charging ports (22.5W/port), it can supply power to 6 devices simultaneously. Built-in six-fold protection (overload, overvoltage, undervoltage, short circuit, overtemperature, and reverse connection), combined with dual intelligent silent cooling fans (noise ≤45dB), balances high-power performance and safety, making it suitable for home emergencies, outdoor engineering, vehicle-mounted power supplies, small commercial and other scenarios.
