In domestic market, the high and low 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, 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: Sine Wave inverter, which uses PWM pulse width modulation to generate modified sine waves. 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 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 with high efficiency, low noise, and moderate price, making it a mainstream product in the market.

Type two: Pure Sine Wave inverter, which adopts 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 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 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. Please note: many customers find it appears unstable when using conventional multimeters to measure voltage. This is because ordinary multimeters can only test pure sine waveforms accurately and calculate values based on that.

Generally speaking, appliances like mobile phones, computers, LCD TVs, incandescents, 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 utilizing electromagnetic induction principles, produced by high-power electrical products such as motors, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, and pumps. These products require power far exceeding their rated power (about 3-7 times) when starting. Therefore, only pure sine wave inverters are suitable for these appliances.

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