Question you may concern
What capacity battery is needed to meet long-term use?
It needs to be calculated according to the total power of the device, the formula is "Battery Capacity (Ah) = Total Device Power (W) × Usage Time (h) ÷ Input Voltage (12V)". For example, to drive a 1000W device for 5 hours, the required battery capacity = 1000×5÷12≈417Ah, it is recommended to use 2 200Ah batteries in parallel (total capacity 400Ah, actual usage about 4.8 hours).
What kind of distributors are you looking for?
We seek distributors with experience in the amusement or entertainment equipment industry and a strong local market presence.
Does the UPS function require additional mains connection?
Yes. The inverter needs to be connected to a home/office socket via the included mains cable, and the device will automatically detect the mains status; when the mains power is interrupted, it will switch to battery power immediately.
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.
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.
