Q&A
Can it drive a 3P air conditioner and an electric oven at the same time?
Total power needs to be calculated: the rated power of a 3P air conditioner is about 2200W-2500W, and the electric oven is about 1500W-2000W. The total power is 3700W-4500W, which exceeds the 3000W continuous power, so simultaneous use is not recommended; if used alone, the 6000W peak can meet the startup needs of both, and the battery capacity must be ≥200Ah (12V) when used alone.
What happens if the positive and negative poles are reversed when connecting the battery?
The device features built-in reverse polarity protection. If the positive and negative terminals are connected incorrectly, the circuit will automatically disconnect to prevent damage to the equipment. Simply adjust the battery clip connections (red clip to positive terminal, black clip to negative terminal), then restore power to resume normal operation.
What appliances can this inverter support?
Rated 1500W, peak 3000W – supports most home appliances.
Which regional plugs can be used with the universal socket?
The universal socket supports most national plug specifications, such as GB, US, EU, etc. (some require adapters), and can meet the use of devices in multiple regions.

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.
