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.
Does it support inductive loads?
Modified sine wave inverters are suitable for resistive loads; for inductive loads, pure sine wave models are recommended.
What is the difference between a pure sine wave inverter and a modified sine wave inverter?
Pure sine wave inverter has an output waveform close to mains power with low distortion rate (<3%), which can be safely adapted to precision devices such as computers, medical instruments, and inverter home appliances; modified sine wave inverter has a notched waveform, which easily causes device heating, malfunction or damage, and is only suitable for simple devices such as bulbs and fans.
How does reverse protection work?
When the positive and negative poles of the battery are reversed, the inverter will automatically cut off the circuit to avoid device damage and ensure power usage safety.
3000W Full-Power Pure Sine Wave Inverter, DC 12V to AC 220V Power Converter, Suitable for High-Power Precision Devices
This 3000W full-power pure sine wave inverter (Model: CS3000PSW) adopts pure sine wave output technology (waveform distortion rate <2%), and the output power is highly consistent with mains power quality. It can safely drive high-power precision loads such as air conditioners, refrigerators, medical instruments, and small industrial equipment, avoiding equipment malfunctions or shortened service life caused by unstable waveforms. The device supports DC 12V input (compatible with 10.5V-14.8V wide voltage), continuously outputs 3000W full power, and has a peak power of 6000W, easily coping with the instantaneous startup impact of high-power devices; it is equipped with 4 AC universal sockets (max current 16A) + 2 USB 3.0 fast-charging ports (22.5W per port) to meet the simultaneous power supply needs of multiple devices. Built-in six-fold safety protection (overload, overvoltage, undervoltage, short circuit, overtemperature, reverse connection), combined with dual intelligent silent cooling fans (noise ≤45dB), it achieves the triple advantages of "high power + high safety + low noise," suitable for home emergency, outdoor engineering, vehicle-mounted power supply, small industrial scenarios and other fields.
