FAQ
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 capacity battery can be used with it?
It is recommended to use a 12V 100Ah-200Ah lead-acid battery or lithium battery; the larger the battery capacity, the longer the UPS power supply time (e.g., a 100Ah battery can support a 100W device to work continuously for about 10 hours).
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.
What is the difference between modified sine wave and pure sine wave?
Modified sine wave is suitable for most ordinary home appliances and electronic devices; pure sine wave is suitable for devices with extremely high power requirements (such as precision instruments). This modified sine wave is more cost-effective and meets the needs of most daily scenarios.

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.
