Frequently Asked Questions
Q
Why is the quotation higher than some other suppliers?
A: In the domestic market, high and low-quality inverter brands are mixed together. Many low-cost inverters are actually assembled in unlicensed workshops. They are built crudely with substandard components to reduce costs, which presents a significant security risk. To protect personal safety and property, please prioritize reliability over low prices and choose a trusted inverter.
Q
How many categories does it have according to the output waveform?
A:
Type One (Modified Sine Wave Inverter): This type uses PWM pulse width modulation to generate a modified sine wave. Featuring a dedicated intelligent circuit and high-power field effect tube, it reduces power loss and includes a soft-start function to ensure reliability. It meets the needs of most electrical equipment that does not demand premium power quality. However, it exhibits a 20% harmonic distortion when running sophisticated equipment and can cause high-frequency interference to radio communications. They are efficient, quiet, moderately priced, and represent the market mainstream.
Type Two (Pure Sine Wave Inverter): This type adopts an isolated coupling circuit design, providing high efficiency, stable output waveform, and high-frequency technology. It is small in size and compatible with all types of loads, including common electrical appliances and inductive devices (such as refrigerators, electric drills, etc.) without causing interference or noise (like buzzing or TV static). Its output is equivalent to or better than the utility grid, as it contains no electromagnetic pollution.
Q
Is the output voltage of the inverter stable?
A: Absolutely. Our inverter is designed with an advanced regulator circuit, keeping the output voltage highly stable. Note that measuring with a conventional multimeter may show unstable readings because ordinary multimeters cannot correctly calculate data for non-pure sine waveforms.
Q
What are resistive load appliances?
A: Generally, appliances like mobile phones, computers, LCD TVs, incandescent bulbs, electric fans, video broadcasts, small printers, electric mahjong machines, and rice cookers belong to resistive loads. Our modified sine wave inverters can power these devices successfully.
Q
What are inductive load appliances?
A: Inductive load appliances utilize electromagnetic induction principles, typically found in high-power motor-driven devices, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, and pumps. These products require 3 to 7 times their rated power during startup. Therefore, only pure sine wave inverters are suitable for running them safely.
Q
What should be noticed when installing the inverter?
A: Install the product in a place that is well-ventilated, cool, dry, and waterproof. Please do not place foreign objects or apply stress to the inverter. Always remember to turn on the inverter before turning on your connected appliances.
