This inverter is a tool that will convert 12-24V DC to 100-240V AC. We offer a variety of modified sine wave inverters (150W-3000W) and pure sine wave inverters (300W-2500W) with an aluminum housing that is light and corrosion resistant. These power inverters include a number of AC and USB sockets, so that they can provide power to a variety of electrical products. The pure sine wave inverter outputs a better waveform with a low distortion rate, consistent with AC from the power grid and is suitable for digital precise equipment and facilities that require high quality power waveform such as radios and medical facilities. Modified sine wave inverters are suitable for most appliances. However, inductive load type electrical appliances such as refrigerators and electrical drills cannot be used simultaneously with a modified sine wave inverter, as there is a risk of damage to both the relevant motor and the inverter. The modified sine wave inverter costs less than a pure sine inverter, thus, we recommend using a modified sine wave inverter if your power requirements are lower.
