Why is the quotation higher than some other suppliers?
In the domestic market, high and low-quality inverter brands are often mixed. Many low-cost inverters are assembled in unlicensed workshops using substandard components to reduce costs, which poses major security risks. To protect personal safety and property, we prioritize premium component sourcing and rigorous testing rather than compromising standards for a low price.
What are the different categories based on the output waveform?
Type One (Modified Sine Wave): Uses PWM pulse width modulation. Integrated intelligent circuits and high-power field-effect tubes reduce power loss and support a soft-start function. It meets basic demands for most electrical equipment, though 20% harmonic distortion can affect sophisticated devices and communication tools.
Type Two (Pure Sine Wave): Uses an isolated coupling circuit design, high-frequency technology, and delivers high stability. Perfect for all kinds of loads, including sensitive inductive loads (refrigerators, electric drills, etc.) without interference (like TV static or buzzing noise). It matches or exceeds the quality of daily grid power.
Is the output voltage of this inverter stable?
Yes, absolutely. The inverter is designed with a reliable regulator circuit. You can verify this output stability using a true RMS multimeter. Standard non-RMS multimeters may provide inaccurate readings as they cannot properly calculate data from pure sine wave outputs.
What are resistive load appliances?
Resistive load appliances generally include mobile phones, computers, LCD TVs, incandescent bulbs, electric fans, video broadcasts, small printers, electric mahjong machines, and rice cookers. Our inverters easily support these device types.
What are inductive load appliances?
Inductive loads work on electromagnetic induction principles and are found in high-power motor-driven appliances, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, water pumps, etc. These items require 3 to 7 times their rated power during startup. Therefore, a pure sine wave inverter is required to run them safely.
What safety precautions should be observed when installing the inverter?
Install the inverter in a well-ventilated, cool, dry, and water-proof location. Avoid putting stress on the casing or inserting foreign objects. Always remember to turn on the inverter first before turning on the connected appliances.
