Frequently Asked Questions
1. Why is your quotation higher than other suppliers?
In the market, inverter qualities vary. Low-cost inverters are often assembled in unlicensed workshops using substandard components, posing significant security risks. To protect personal and property safety, always choose a reliable inverter rather than focusing solely on a low price.
2. What are the categories based on output waveform?
Type One: Modified Sine Wave. Uses PWM modulation. Suitable for most basic electrical equipment. It may have 20% harmonic distortion, which can interfere with sophisticated or radio equipment.
Type Two: Pure Sine Wave. Adopts isolated coupling circuit design. High stability and efficiency. Suitable for all loads, including inductive ones like refrigerators and drills, without interference or noise.
3. Is the output voltage of our inverter stable?
Absolutely. Our inverters feature a high-quality regulator circuit. While ordinary multimeters might show unstable readings (as they are designed for pure sine waves only), a true RMS multimeter will confirm the output is quite stable.
4. What are resistive load appliances?
These include mobile phones, computers, LCD TVs, incandescent lights, electric fans, rice cookers, and small printers. Our modified sine wave inverters can power these successfully.
5. What are inductive load appliances?
These products use electromagnetic induction, such as motors, compressors, refrigerators, air conditioners, pumps, and fluorescent lamps. These require 3-7 times their rated power during startup. Only pure sine wave inverters are suitable for these devices.
6. What should be noticed during installation?
Place the inverter in a well-ventilated, cool, dry, and waterproof location. Do not place foreign objects on or inside the unit. Always turn on the inverter before turning on the connected appliance.
