The brands of inverters are mixed, and the quality is uneven. There are a lot of low-priced inverters that are actually of substandard quality, and they are assembled with unqualified components in order to reduce costs, making the product very dangerous to use. In order to protect personal and property safety, please do not covet low prices, and must choose safe and reliable inverters!
Type 1: Modified sine wave inverter, using PWM pulse width modulation to generate a modified sine wave. Due to the use of intelligent special circuits and high-power field effect tubes, the power loss is greatly reduced and the soft-start function is added, which effectively guarantees the reliability of the inverter. If the requirements for power quality are not high, it can meet the needs of most electrical equipment. However, there are still 20% harmonic distortion problems when precision equipment is running, and it will also cause high-frequency interference to communication equipment. This kind of inverter can meet most of our basic needs for electricity and has become a mainstream product in the market because of its moderate price.
Type 2: Pure sine wave inverter, designed with isolated coupling circuit, high efficiency, high output waveform stability, high-frequency technology, small size, suitable for various loads, can be connected to any common electrical equipment and inductive load equipment, no noise disturbance. The output of the pure sine wave inverter is the same as our daily grid-connected power supply, or even better because it does not have grid-connected electromagnetic pollution.
certainly. Our inverter is designed with a good voltage-stabilizing circuit. You can check it with a multimeter. In fact, the output voltage is quite stable. A special explanation is needed here: Many customers find unstable voltages when using traditional multimeters to measure voltages because ordinary multimeters can only test pure sine waveforms and calculate data.
Generally speaking, electrical appliances such as mobile phones, computers, LCD TVs, incandescent lamps, electric fans, video broadcasting, small printers, electric mahjong machines, and rice cookers are all resistive loads. Our modified sine wave inverters can successfully drive them.
Refers to the application of the principle of electromagnetic induction to produce high-power electrical products, such as motors, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, water pumps, etc. These products’ power far exceeds the rated power (about 3-7 times) when starting. So they can only use a pure sine wave inverter.
Place the product in a well-ventilated, cool, dry, and waterproof place. Please do not put heavy pressure or put foreign objects into the inverter. Remember to turn on the inverter before turning on the appliance.
