Q: what is peak output power?

A: peak power refers to the power that the AC power supply can bear at the moment of starting up, usually refers to the load of motor type. When starting, the instantaneous starting power caused by large starting current is called peak output power.

Q: what is the difference between the continuous output power and the peak output power?

A: continuous power and peak power are different because of their significance.

Continuous load = current value × 220 (AC voltage)

Starting load = (3 ~ 7) × Power value

Generally speaking, whether electrical appliances or electric tools can be started depends on whether your inverter power has the ability to drive it.

Q: what is perceptual load?

A: generally, the load with inductive parameters, that is, the load with current leading voltage characteristics, is regarded as inductive load. Generally speaking, it refers to the high-power electrical products made by the principle of electromagnetic induction, such as motors, compressors, relays, fluorescent lamps, etc. This kind of products need a much larger starting current (about 3-7 times) than the current required to maintain normal operation. For example, a refrigerator that consumes about 150 watts of electricity during normal operation can have a starting power of more than 1000 watts. In addition, the inductive load will produce back EMF voltage at the moment when the power is turned on or off, and the peak value of this voltage is far greater than the voltage that the on-board AC power supply can bear, which can easily cause the instantaneous overload of the vehicle inverter and affect the service life of the inverter. Therefore, this kind of electrical appliances have higher requirements for power supply waveform.

Q: what is capacitive load?

A: generally, the load with capacitance characteristic parameters, that is, the load with voltage leading current characteristic, is called capacitive load.

Q: what is the difference between inductive load and capacitive load?

A: the load characteristics are different. First of all, when selecting the load, it must conform to the rated power of on-board AC power supply. As long as the service conditions of the vehicle AC power supply are satisfied, the capacitive and inductive load effects are the same.

Q: what's the difference between the output waveform of vehicle AC power supply and the output voltage of 220 V?

A: the output of AC power supply is analog sine wave, while the utility is real sine wave.

Q: what's the difference between the output voltage value of on-board AC power supply and the output voltage value of 220 V?

Answer: the output voltage of the AC power supply is the same as that of the city.

Q: what is the most common fault of on-board AC power supply? How to exclude?

A: when using the on-board AC power supply, in case of shutdown and alarm, check the following items:

1) Whether the power of the driven electrical appliances exceeds the rated power of the inverter.

2) Whether the on-board AC power supply is well connected with batteries and electrical appliances.

3) If it is stopped during use, whether it is a temperature alarm or not, it can continue to be used after a period of time.

Q: what is on-board AC power supply?

A: vehicle AC power inverter, also known as vehicle power supply, vehicle inverter, power converter, etc., can convert low-voltage (DC12V or DC24V) DC power into AC220V AC power, which is the same as the municipal power supply for general electrical appliances. It is a convenient vehicle power converter.
