Frequently Asked Questions
Why is the quotation different between suppliers?
The market contains mixed brands. Low-cost inverters often use substandard components in unlicensed workshops, posing security risks. Always choose a reliable inverter to protect personal and property safety.
What are the main categories of inverters based on waveform?
1. Modified Sine Wave: Cost-effective, suitable for most equipment but may have 20% harmonic distortion. 2. Pure Sine Wave: High stability, isolated circuit design, suitable for all loads including sensitive inductive devices like refrigerators and drills without interference.
Is the output voltage stable?
Yes. Our inverters feature advanced regulator circuits. Note that ordinary multimeters may show incorrect readings because they are often designed only for standard grid waveforms; a true RMS multimeter is required for accurate measurement.
What are resistive load appliances?
These include mobile phones, computers, LCD TVs, incandescent lights, electric fans, and rice cookers. Modified sine wave inverters can power these successfully.
What are inductive load appliances?
These are products using electromagnetic induction like motors, compressors, refrigerators, and air conditioners. They require 3-7 times their rated power during startup, so only pure sine wave inverters are suitable.
What should be noticed during installation?
Place the unit in a well-ventilated, cool, dry, and waterproof location. Do not place objects on the inverter and ensure the inverter is turned on before connecting the appliance.
