1. What is the difference between a pure sine wave inverter and a modified sine wave inverter?
Modified sine wave inverters use less elaborate switching and filter circuits. When supplying certain loads, electrical noise or interference occurs. The frequency and voltage on the outputs may vary and contain a certain level of noise and distortion. It can operate some resistive loads such as bulbs etc, but is not suitable for inductive devices.
The pure sine wave inverter produces pure sine wave that are just as good as the mains power supply, without electrical noise or interference. The pure sine wave inverters have a significant advantage over modified sine wave inverters in terms of power and power consumption: Choose the pure sine wave inverter for the quality and longevity of your devices.
2. How to choose a suitable power of the inverter?
For resistive loads (TV, computers, fans, lamps, water heaters), please choose an inverter with a higher power than the rated power. For example, for 800 W stove, please choose 1000 W inverter
With inductive load (refrigerator, air conditioning, pump, motor, compressor, pumps, microwave, washing machines, etc.), the shock performance may be 3-7 times higher. Please choose an inverter with a power of 5-10 times or higher. For example, we would recommend 2000W inverter for 1 HP air conditioner (735W).
