Rated power: Rated power refers to the power of the inverter when it is working normally. Its value is the rated voltage of the appliance multiplied by the rated current. If the actual power of the appliance is greater than the rated power, the appliance may be damaged; If the actual power is less than the rated power, the electrical appliance cannot operate normally.

Continuous power: The output power of the host to allow long-term continuous operation under the environmental conditions specified in the current relevant standards.

Instantaneous (peak) power : refers to the maximum power that can be reached in a short period of time, usually only for about 30 seconds. Under normal circumstances, the peak power of the power supply can exceed the maximum output power by about 50% 

Input voltage (range) : refers to the voltage provided by the external power supply to the inverter, the general inverse inverter voltage is 12V\24V\36V\48V\60V\72V 

Instantaneous (peak) power : refers to the maximum power that can be reached in a short period of time, usually only for about 30 seconds. Under normal circumstances, the peak power of the power supply can exceed the maximum output power by about 50% 

Output voltage (range) : The inverter boost output into AC (AC) voltage, generally 110V and 220V two, the frequency of 50hz and 60hz

Frequency : The number of cycles per second that the sine wave of an AC power supply occurs is called the frequency. It is expressed in Hz (Hertz) as the unit of the cycle number of sine waves per second of the power supply. China's power grid is 50 cycles per second = 50Hz, and other countries or regions have 60Hz.

USB output : The inverter has a USB interface and can provide a +5V current output greater than 500ma

Output waveform : The output waveform is the waveform that describes the voltage output of the inverter power supply, which is determined by the working principle of the inverter power supply. The general output waveform of the inverter is sine wave or modified sine wave

Pure sine wave inverter : the output waveform is pure sine wave, compared with the corrected sine wave, this waveform is stable, no distortion, not easy to deformation, strong load capacity, sine wave inverter output is the same as our daily use of the grid or even better sine wave AC, because it does not exist in the grid electromagnetic pollution. With inductive loads such as microwave ovens and motors, it has the ability to make the load work faster and effectively reduce the noise generated by the equipment. Provide continuous and stable AC power to ensure the continuous normal operation of the equipment.

Repair sine wave inverter : repair sine wave is also called quasi sine wave (or improved sine wave, analog sine wave, etc.). Modified sine wave is a waveform between sine wave and square wave, and its output waveform has a time interval between the positive maximum and the negative maximum, but the waveform of quasi-sine wave is still composed of broken lines, which belongs to the category of square wave and has poor continuity. Modified sine wave inverters should avoid “ Inductive load” . In popular terms, that is, the application of electromagnetic induction principle of high-power electrical products, such as motors, compressors, relays, fluorescent lamps and so on. This type of product requires a starting current that is much larger than the current required to maintain normal operation (about 5-7 times). For example, a refrigerator that consumes about 150 watts in normal operation can have a starting power of more than 1,000 watts. In addition, because the inductive load at the moment of switching on the power or turning off the power supply, the reverse electromotive force voltage will be generated, and the peak value of this voltage is far greater than the voltage value that the vehicle inverter can withstand, it is easy to cause the instantaneous overload of the vehicle inverter, affecting the service life of the inverter. Modified sine waves are also called quasi-sine waves (or improved sine waves, simulated sine waves, etc.). Modified sine wave is a waveform between sine wave and square wave, and its output waveform has a time interval between the positive maximum and the negative maximum, but the waveform of quasi-sine wave is still composed of broken lines, which belongs to the category of square wave and has poor continuity.

Inductive load : Under normal circumstances, the load with inductive parameters is generally called inductive load. To be exact, it should be the load current lagging the load voltage of a phase difference characteristic for the inductive load, such as transformers, motors and other loads, called inductive load. Inductive load: Some devices consume reactive power while consuming active power. Inductive load: A circuit with a coil load is called inductive load.

Lamps that rely on gas conduction are inductive loads, such as fluorescent lamps, high-pressure sodium lamps, mercury lamps, metal halide lamps, etc.; Relying on the resistance wire light is a resistive load, such as: tungsten iodide lamp, incandescent lamp, resistance furnace, oven, electric water heater, hot oil tin and so on.

High-power electrical products made by the principle of electromagnetic induction, such as motors, compressors, relays, fluorescent lamps, etc., require a starting current much larger than the current required to maintain normal operation (about 3-7 times) at the start of such products. For example, a refrigerator that consumes about 150 watts in normal operation can have a starting power of more than 1,000 watts. 

Output current : Scientifically, the amount of electricity passing through any cross section of the conductor in unit time is called current intensity, referred to as current. Usually denoted by the letter I, its unit is the ampere, “ Ann ” , symbol “A”.

No-load loss : No-load loss is a constant loss. It is independent of the current passing through, but is related to the voltage to which the component is subjected. Usually we understand it as the energy consumption when the load is not loaded.

Conversion efficiency : It is the ratio of output watts to input watts, if the number is closer to 1, the better the efficiency is displayed, in terms of inverters, the general efficiency is about 70%~80%, that is, the input 1000W, the output is about 700W~800W, the inverter itself consumes 200W~300W of power.

W(Watt) : The watt (symbol: W) is the unit of power in the International System of Units. Watt is defined as 1 joule per second (1 J/s), the rate at which energy (measured in joules) is converted, used, or dissipated per second. In electrical units, it's 1 volt. Ampere (1 V· A, or 1 volt-ampere).

Low voltage protection : The inverter provides electrical safety protection device, it has an intelligent anti-high voltage device built in, in the case of abnormal low voltage input, it will intelligently start the internal protection device to ensure the power safety of the inverter and back-end electrical appliances. The low voltage protection relay in the inverter is connected to both ends of the power supply, and when the input voltage is lower than a certain value of the allowed access voltage, it will automatically trip to separate the circuit breaker switch.

Overload protection : Overload protection equipment installed to prevent the main power line from overheating and damaging the protector due to overload. Overload is a broad term that can refer to excessive load on electrical equipment or excessive force on objects. On these beyond "; Load" The protection made by the behavior is collectively referred to as overload protection. In the power supply system, the function of automatically disconnecting the power supply device due to excessive load is called overload protection.

High voltage protection : The inverter provides electrical safety protection device, it has an intelligent anti-high voltage device built in, in the event of an instantaneous high voltage input anomaly, it will intelligently start the internal protection device to ensure the power safety of the inverter and back-end electrical appliances.

Overtemperature protection : When the inverter exceeds the maximum allowable working temperature value, the inverter automatically breaks off, interrupting the work to ensure the safety of electricity consumption.

Operating temperature : refers to a temperature range in which the inverter works normally. In this working range can ensure the normal operation of the instrument.

Operating humidity : indicates a humidity range for the normal operation of the inverter. In this working range can ensure the normal operation of the instrument.

Power frequency : refers to the frequency of the AC power supply used in industry, one of the important indicators of electrical quality in unit Hertz (Hz).
