Frequently Asked Questions
Why is this quotation different from other suppliers?
In the market, inverter qualities vary greatly. Low-cost inverters often come from unlicensed workshops using substandard components, posing significant security risks. To protect personal and property safety, it is essential to choose a reliable, high-quality inverter rather than just focusing on the lowest price.
What are the categories of inverters based on output waveform?
There are two main types:
1. Modified Sine Wave Inverter: Uses PWM modulation. It is efficient, cost-effective, and suitable for most basic electrical equipment.
2. Pure Sine Wave Inverter: Features an isolated coupling circuit. It provides high stability, similar to or better than grid power, and is compatible with all loads, including sensitive inductive loads like refrigerators and drills.
Is the output voltage of the inverter stable?
Yes, our inverters are designed with advanced regulator circuits. Note that ordinary multimeters may show incorrect readings for modified sine waves; a true RMS multimeter is required for accurate measurement.
What are resistive load appliances?
Resistive loads include devices like mobile phones, computers, LCD TVs, incandescent lights, electric fans, and rice cookers. Our modified sine wave inverters can successfully power these devices.
What are inductive load appliances?
Inductive loads work on electromagnetic induction principles, such as motors, compressors, refrigerators, air conditioners, and pumps. These products require 3-7 times their rated power during startup. Pure sine wave inverters are recommended for these applications.
What should be noticed during installation?
Install the inverter in a well-ventilated, cool, dry, and waterproof location. Ensure there are no foreign objects inside the unit and always turn on the inverter before turning on the connected appliances.
