In the domestic market, high and low-quality inverter brands are mixed together. There are many low-cost inverters produced by assembled small unlicensed workshops. They crudely reduce costs by using substandard components for assembly, presenting a very large security risk! In order to protect personal safety and property, please do not covet low prices, and be sure to choose a reliable inverter.

Type one: Modified Sine Wave inverter, which uses PWM pulse width modulation to generate a modified sine wave. Due to the usage 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 high power quality is not demanded, it meets the needs of most electrical equipment. However, 20% harmonic distortion issues still exist when running sophisticated equipment, which can also cause high-frequency interference to radio communications equipment. This kind of inverter meets basic power needs with high efficiency, low noise, and a moderate price, making it a mainstream product in the market.

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

Absolutely. Our inverter is designed with a reliable regulator circuit. You can verify this when measuring the true value with a multimeter; the output voltage is indeed quite stable. Special explanation: many customers find it seems unstable when using a conventional multimeter to measure voltage. This operation is incorrect, as ordinary multimeters can only test pure sine waveforms and calculate standard data.

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.

Inductive loads refer to applications using electromagnetic induction principles produced by high-power electrical products, such as motor-type compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, and pumps. These products' startup power is far greater than their rated power (about 3-7 times). Therefore, only pure sine wave inverters are suitable for these applications.

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