In the market, high and low inverter brands are mixed together. There are many low-cost inverters that are actually assembled in small unlicensed workshops. They are built crudely, reducing costs by using substandard components for assembly, which presents a very big security risk! In order to protect personal and property safety, 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 an intelligent dedicated circuit and high power field effect tube, it greatly reduces the power loss and increases the soft-start function, effectively ensuring the reliability of the inverter. If the 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 can meet the basic needs of most of our power needs, featuring high efficiency, low noise, and a moderate price, thus becoming the 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. Small in size and suitable for all kinds of load, it 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 electromagnetic pollution.

Absolutely. Our inverter is designed with a good regulator circuit. You can even check it when measuring the true value using a multimeter. Actually, the output voltage is quite stable. Here we need to make a special explanation: many customers found it is unstable when using a conventional multimeter to measure voltage. We can say the operation is incorrect. An ordinary multimeter can only test pure sine waveforms and calculate data.

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

It refers to the application of electromagnetic induction principles, produced by high-power electrical products such as motor types, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, pumps, etc. These products' startup power is far more than the rated power (about 3-7 times). Therefore, only pure sine wave inverters are suitable for them.

Put the product in a place that is well ventilated, cool, dry, and waterproof. Please do not stress the inverter or put foreign objects into it. Remember to turn on the inverter before turning on the connected appliances.
