In the domestic market, high and low quality inverter brands are mixed together. Many low-cost inverters are actually assembled in small unlicensed workshops. They crudely use substandard components to reduce costs, posing a very big security risk! To protect personal and property safety, please do not prioritize a low price, and be sure to choose a reliable, high-quality inverter.

Type one: Modified Sine Wave inverter, which uses PWM pulse width modulation to generate a modified sine wave. Due to the use of intelligent dedicated circuits and high-power field effect tubes, it greatly reduces power loss and adds a soft-start function, effectively ensuring the reliability of the inverter. If power quality is not highly demanded, it is able to meet the needs of most electrical equipment. However, 20% harmonic distortion issues remain when running sophisticated equipment, which can also cause high-frequency interference to radio communications equipment. This kind of inverter meets the basic needs of most appliances with high efficiency, low noise, and moderate prices.

Type two: Pure Sine Wave inverter, which adopts an isolated coupling circuit design. It features high efficiency, high stability of the output waveform, and high-frequency technology. It is small in size and suitable for all kinds of loads, connecting to any common electrical devices and inductive load devices (such as refrigerators, electric drills, etc.) without interference (e.g., buzz and TV noise). The output of a pure sine wave inverter is the same as, or even better than, the grid power we daily use, as it does not present grid electromagnetic pollution.

Absolutely. Our inverter is designed with an advanced regulator circuit. You can verify this by measuring the value with a true RMS multimeter. The output voltage is highly stable. Note: many customers find it seems unstable when using conventional multimeters to measure voltage because ordinary multimeters cannot correctly test and calculate non-pure sine waveforms.

Generally speaking, appliances like mobile phones, computers, LCD TVs, incandescent lights, electric fans, video broadcasts, small printers, electric mahjong machines, and rice cookers all belong to resistive loads. Our modified sine wave inverters can drive them successfully.

These refer to appliances that utilize electromagnetic induction principles, typically high-power products with motors, compressors, relays, or compressors. Examples include motors, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, and pumps. These products draw far more power (about 3-7 times) than their rated power during startup. Therefore, only a pure sine wave inverter is suitable for them.

Place the product in a location that is well-ventilated, cool, dry, and waterproof. Please do not apply stress or insert foreign objects into the inverter. Remember to turn on the inverter before turning on the connected appliance.
