QWhy is the quotation higher than some other suppliers?
In the domestic market, high and low-quality inverter brands are mixed together. There are many low-cost inverters produced by assembled, unlicensed workshops. They crudely reduce costs by using substandard components for assembly, presenting a significant security risk. To protect personal safety and property, please choose a reliable, high-quality inverter rather than focusing solely on a low price.
QHow many categories are there according to the output waveform?
Type One (Modified Sine Wave Inverter): Uses PWM pulse width modulation to generate a modified sine wave. Due to the use of an intelligent dedicated circuit and high-power field effect tube, it greatly reduces power loss and adds a soft-start function, ensuring reliability. It meets the needs of most electrical equipment where power quality demands are not highly strict. However, it still exhibits 20% harmonic distortion issues when running sophisticated equipment and can cause high-frequency interference to radio communications.
Type Two (Pure Sine Wave Inverter): Adopts an isolated coupling circuit design, providing high efficiency, high stability of the output waveform, and high-frequency technology. It is small in size and suitable for all kinds of loads. It can be connected to common electrical and inductive load devices (such as refrigerators, electric drills, etc.) without interference (e.g., buzz and TV noise). The output is equal to or better than the daily utility grid power, without electromagnetic pollution.
QIs the output voltage of the inverter stable?
Absolutely. The inverter is designed with a reliable regulator circuit. You can verify this by measuring the true value with a multimeter. Please note that when using conventional multimeters to measure the voltage, the reading might appear unstable. Ordinary multimeters can only correctly test pure sine waveforms and calculate data.
QWhat are resistive load appliances?
Generally speaking, appliances like mobile phones, computers, LCD TVs, incandescent lights, electric fans, video broadcasts, small printers, electric mahjong machines, and rice cookers belong to resistive loads. Modified sine wave inverters are capable of driving these appliances successfully.
QWhat are inductive load appliances?
These refer to appliances operating on electromagnetic induction principles, typically high-power products with motors, compressors, relays, or fluorescent lights. Examples include compressors, electric stoves, refrigerators, air conditioners, energy-saving lamps, and pumps. These products draw a startup power that is 3 to 7 times their rated power. Therefore, only pure sine wave inverters should be used to power them.
QWhat should be noticed when installing the inverter?
Place the product in a well-ventilated, cool, dry, and waterproof location. Do not stress the unit or insert foreign objects into the inverter. Always remember to turn on the inverter before switching on the connected appliance.
