In the domestic market, high and low-quality inverter brands are mixed together. There are many low-cost inverters produced by small unlicensed workshops. They rudely use substandard components for assembly to reduce costs, presenting a very large security risk! In order to protect personal safety and property, please do not covet low prices; 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 an intelligent dedicated circuit and high-power field effect tube, 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 problems still exist 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 of our appliances 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. It features high efficiency, high stability of the output waveform, high-frequency technology, and a small size. It is suitable for all kinds of loads, connecting 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 generate electromagnetic pollution.

Absolutely. Our inverter is designed with a high-quality regulator circuit. You can verify this by measuring the true value with a multimeter. The output voltage is highly stable. Note: many customers find it seems unstable when using conventional multimeters to measure voltage. This operation is incorrect, as ordinary multimeters can only correctly test and calculate pure sine wave 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 run them successfully.

This refers to high-power electrical products produced by the principle of electromagnetic induction, such as motors, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, and pumps. These products require far more power (about 3-7 times) than their rated power upon startup. Therefore, only a pure sine wave inverter can support 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.
