The inverter using the basic common sense

1. Q: What is an inverter and what role does it play?

Answer: Simply speaking, inverter is an electronic device that converts low voltage (DC 12V/24V/36V/60V) direct current into 220V alternating current. Because we usually use 220V alternating current rectifier into direct current, and the function of inverter is on the contrary, so it is named. We are in a "mobile" era, mobile office, mobile communication, mobile leisure and entertainment. In the moving state, people not only need low voltage direct current supplied by batteries or batteries, but also need 220V alternating current which is indispensable in our daily environment, inverter can meet our demand.

2. Q: According to the output waveform, what types of inverters are divided?

Answer: There are mainly two types, one is pure sine wave inverter, and the other is quasi-sine-wave inverter. Modified sine wave is also called quasi-sine wave (or modified sine wave, analog sine wave, etc.).

The output waveform of the pure sine wave inverter is pure sine wave. This waveform is stable, undistorted, not easily deformed, and has strong carrying capacity, which is close to the power supply capability of the mains. With inductive loads such as microwave oven and motor, it can make the load work faster and effectively reduce the noise generated by the equipment. Provide continuous and stable alternating current to ensure the continuous and normal operation of the equipment. The output waveform of modified sine wave is modified sine wave. Switching inverter power supply uses PWM pulse width modulation to generate modified wave output. In the inverter process, due to the use of dedicated intelligent circuit and high power FET, the power loss of the system is greatly reduced, and the soft start function is added, which effectively ensures the reliability of the inverter. Sine wave repair is used in inverter, which can basically meet most of our electricity demand, with high efficiency, low noise and moderate price, thus becoming the mainstream product in the market.3. Q: What is "emotional load"?Answer: Generally speaking, high-power electrical appliance products made by applying electromagnetic induction principle, such as motor, compressor, relay, fluorescent lamp, etc. This kind of product needs a starting current which is much larger (about 3-7 times) than the current needed to maintain normal operation when starting. For example, the starting power of a refrigerator that consumes about 150 watts during normal operation can be as high as over 1000 watts. In addition, since the inductive load will generate back electromotive force voltage at the moment when the power supply is turned on or off, the peak value of this voltage is far greater than the voltage value that the inverter can bear, it is easy to cause the instantaneous overload of inverter, which affects the service life of inverter. Therefore, this kind of electrical appliances have higher requirements on the power supply waveform.

4. Q: What is the efficiency of inverter?Answer: inverter itself also consumes a part of electricity when it is working, therefore, its input power is greater than its output power. The efficiency of inverter is the ratio of input power and output power of inverter. If an inverter inputs 100 watts of direct current and outputs 90 watts of alternating current, then its efficiency is 90%.5. Q: What is continuous output power? What is the peak output power?Answer: Some electrical appliances or tools using electric motors, such as refrigerators, washing machines, electric drills, etc., need a large amount of current to push them at the moment of starting. Once the starting is successful, then only a small current is needed to maintain its normal operation. Therefore, for inverter, there are concepts of continuous output power and peak output power. Continuous output power is the rated output power, but also the general peak output power is the rated output power of 2 times. It must be emphasized that the starting current of some electrical appliances, such as air conditioners and refrigerators, is 3-7 times of the normal working current. Therefore, only the inverter that can meet the starting peak power of electrical appliances can work normally.

6. Q: How should I connect inverter with power supply and load?Answer: using electrical appliances below 300W can directly plug the 300W Inverter plug into the cigarette lighter socket for use. Inverter with more than 300 watts is directly connected to the battery through alligator wire, and the red line is connected to the positive pole of the battery, and the black line is connected to the negative pole of the battery (do not reverse, remember!) If the electric location is far away from the battery, the connection principle of the inverter is: the connection between the inverter and the battery should be as short as possible, while the output line of 220V alternating current should be longer.

7. Q: What is the risk of using inverter?Answer: the wire from the car battery to the inverter input is carrying a very large current. If the copper wire is hot or even eventually caught fire due to the poor quality of the wire, too thin wire or excessive load, it will lead to a very a nasty accident. Therefore, during the use of inverter, it must be operated strictly in accordance with the provisions of user manual.8. Q: How do I know the capacity of the battery?

Answer: There are many letters and numbers printed on the battery. As long as you find the word XXAH, you can know how large the battery is. Let's talk about the meaning of AH first. A represents amp., that is, the unit of current, and H represents hour. The two letters together mean "ampere hour", which means how many amps of current can be continuously output in one hour. The previous XX is usually two numbers, namely the number of amps. For example, 45AH represents that this battery can output (12V) 45 amps of current in one hour. As for the power that this battery can output, we use 12v multiplied by 45 amps to get 540W, which is the output power of this battery (theoretical value).

9. Q: How to equip the battery with a suitable inverter?Answer: If the specification of the battery is 12v 50 amps, we use 12v multiplied by 50 amps to get the output power of the battery is 600 watts. If the efficiency of the inverter is 90%, then we multiply 90% by 600W to get 540W. That is to say, your battery can push an inverter with a maximum output power of 540W. Of course, you can also adopt the procurement method of "one step in place", that is, regardless of the specifications of the battery currently used on your car, you can buy an inverter with an output power of 800W. Then, first use it within the allowable range of the current battery, and use it at full power after changing a larger car in the future. Finally, the power requirement for inverter is not high. For example, 100W is enough, then you can buy a low-power inverter. In addition, when determining the power of the inverter, there is another important principle, that is, when using the inverter, do not run at full load for a long time, otherwise the life span of the inverter will be greatly shortened, at the same time, the failure rate of inverter will also increase significantly. We strongly recommend users to use inverter under the condition of no more than 85% of rated power.

10. Question: What should we pay attention to when using vehicle inverter?Answer: First of all, the inverter should be used strictly in accordance with the provisions of the user manual; Secondly, the output voltage of the inverter is 220V alternating current, however, this 220V electricity is in a narrow space and in a movable state, so you should be very careful. It should be placed in a safer place (especially away from children!), To prevent electric shock. When not in use, it is better to cut off its input power. Third, do not place the inverter in direct sunlight or near the outlet of the heater. The working environment temperature of inverter should not exceed 40 degrees centigrade. Fourth, the inverter will generate heat when working, so do not place objects near or above it. Fifth, inverter is afraid of water, do not let it rain or sprinkle water.11. Q: Why is the displayed voltage lower than 220V when using ordinary multimeter to measure the AC output of quasi-sine wave inverter?Answer: This is normal, because when measuring the AC voltage of quasi sine wave, a universal watch with "true effective value" should be used to get the correct reading.

The inverter of the use

1) power supply options

power supply must be provided by storage battery or auto cigarette lighter. 12V, 24V, 48V and 60V can be selected according to different finished products.

2) connect to Inverter to power supply

turn OFF the switch of inverter and all devices in the "OFF" state.

A: Battery Power supply: connect the negative pole of the battery to the black terminal (-) of the inverter, and connect the positive pole of the battery to the red terminal (+) of the inverter.

B: auto cigarette lighter power supply: The dedicated connection line of the cigarette lighter is connected to the red terminal of the inverter according to the red line. After the black line is connected to the black terminal of the inverter, plug the cigarette lighter into the auto cigarette lighter.

3) connect to Inverter to electrical appliance

make sure that the load battery is the nominal power supply of the inverter, and the starting current cannot exceed the peak capacity of the inverter. After connecting the inverter and electrical appliances, turn on the inverter and electrical appliances.

4)turn on the inverter switch, the buzzer is turned on, and the cooling fan is started. If the performance is normal, stop ringing fan speed halving, green color indicator light on, indicating normal operation. The display of digital tube changes from "---" to the display of actual input and output voltage data. The above three figures show the input voltage with an accuracy of 0.1V, while the following three figures show the output voltage with an accuracy of 1V.

5) If the load power is higher than the rated output power of the inverter, the overload protection will automatically turn off the output voltage of this product, and the indicator light will turn red at the same time, and the output voltage of the digital tube will be displayed as "000". Please remove the load. After connecting the load less than the rated power, the machine will start automatically after two seconds, or restart the machine through the inverter switch.

6)if there is no output on the boot and an alarm is given, the cause of the failure will be judged by ringing. If the sound is rapid (about three times per second), the input voltage is higher than the input safe potential, and the voltage is displayed on the digital tube; If the sound is flat (about one second) the input voltage is lower than the normal working voltage, and the voltage is displayed on the digital tube; When the sound is slow (about 2 seconds), it is caused by the excessive internal temperature. At this time, the cooling fan will rotate at full speed, when the temperature drops to the safe working temperature, the machine will start automatically.

Tip:the design of storage battery can provide instantaneous large current when starting, and they are not suitable for deep discharge. If non-UPS products are used until the under voltage is turned off, the input power supply should be disconnected and the storage battery should be charged to avoid affecting the service life of the storage battery.

Note:although this product is equipped with overvoltage protection function, if the input voltage exceeds the working voltage of adaptable product, it may still damage this product.
