Q&A
Does it have a charging (UPS) function?
No, this model is a pure inverter without UPS function.
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.
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.
Can it be connected to a battery long-term?
Yes, ensure good ventilation to avoid overheating.
