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

Type one: 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 power quality is not highly demanded, it is able to meet the needs of most electrical equipment. However, it still exhibits 20% harmonic distortion 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 power, showing high efficiency, small noise, and a moderate price, thus becoming 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. Suitable for all kinds of loads, 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 grid electromagnetic pollution.

Absolutely. Our inverter is designed with a good regulator circuit. You can even check it when measuring the true value with a multimeter. Actually, the output voltage is quite stable. Note: many customers find it seems unstable when using a conventional multimeter to measure voltage. This operation is incorrect because 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 broadcast systems, 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 motors, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, pumps, etc. These products' startup power is far more than their rated power (about 3-7 times) when starting. Therefore, only a pure sine wave inverter is suitable for them.

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