1 Resistive electrical appliances

Generally, pure resistive loads that work through resistive elements are called resistive loads, such as induction cookers, mobile phones, computers, LCD TVs, incandescent lamps, electric fans, mahjong machines, audio-visual players, small printers, water dispensers, rice cookers, etc. Electrical appliances are all resistive loads.

2 inductive appliances

High-power electrical appliances made with the principle of electromagnetic induction, such as motors, compressors, air conditioners, refrigerators, washing machines, water pumps, air compressors, etc., the starting power of these products exceeds the rated power (3-12 times)

How to choose a suitable battery for inverter

Working time = U (voltage payment) × I (battery capacity) × 0.8 × 0.9 ÷ electrical power

Example: a 12V 50AH battery with a 220V 100W bulb
Working time=12Vx50AH×0.8×0.9÷100W=4.32(hours)

Note: 0.8 is the battery discharge coefficient (constant) 0.9 is the conversion efficiency of the inverter (constant)

How long it can be used is also related to the new and old performance of your battery

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

Answer: To put it simply, an inverter is an electronic device that converts low-voltage (DC 12V/24V/36V/60V) DC power into 220V AC power. It is named because we usually use 220V AC rectification to change it into DC, while the inverter has the opposite effect. We are in a “mobile” era, mobile office, mobile communication, mobile leisure and entertainment. In the mobile state, people not only need low-voltage DC power supplied by batteries or batteries, but also need 220V AC power which is indispensable in our daily environment. Inverters can meet this demand.

2: According to the output waveform, how many types of inverters are there?

Answer: There are mainly two types: pure sine wave inverter and modified sine wave inverter. Modified sine wave is also called quasi sine wave (or improved sine wave, simulated sine wave, etc.).
The output waveform of the pure sine wave inverter is pure sine wave, which is stable, not distorted, not easy to deform, and has strong load capacity, close to the power supply capacity of the city power. With inductive load, 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 AC power to ensure continuous and normal operation of equipment. The output waveform of the modified sine wave is the modified sine wave. The switching inverter uses PWM pulse width modulation to generate the modified wave output. During the inverter process, the special intelligent circuit and high-power FET are used, which greatly reduces the power loss of the system, and adds the soft start function, effectively ensuring the reliability of the inverter. The modified chord wave is used in the inverter, which can basically meet most of our power demand, with high efficiency, low noise and moderate price, so it has become the mainstream product in the market.

3. Question: What is “perceptual load”?

Answer: Generally speaking, it refers to high-power electrical products made with electromagnetic induction principle, such as motors, compressors, relays, fluorescent lamps, etc. This type of product requires a much higher starting current (about 3-7 times) than the current required to maintain normal operation when starting. For example, a refrigerator that consumes about 150W during normal operation can have a starting power of more than 1000W. In addition, as the inductive load will generate the back EMF voltage at the moment of connecting or disconnecting the power supply, the peak value of this voltage is far greater than the voltage value that the inverter can withstand, it is easy to cause the instantaneous overload of the inverter and affect the service life of the inverter. Therefore, this kind of electrical appliances have high requirements for power supply waveform.

4. Q: What is the efficiency of the inverter?

Answer: The inverter itself consumes part of the power when it works, so 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 100W DC and outputs 90W AC, its efficiency is 90%.

5. Question: What is the continuous output power? What is the peak output power?

Answer: Some electric appliances or tools that use electric motors, such as refrigerators, washing machines, electric drills, etc., need a large current to push them at the moment of starting. Once they are started successfully, they only need a small current to maintain their normal operation. Therefore, for the inverter, the concepts of continuous output power and peak output power are also introduced. The continuous output power is the rated output power; Generally, the peak output power is twice the rated output power. 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 peak power of electrical startup can work normally.

6. Question: How should the inverter be connected to the power supply and load?

Answer: For appliances under 300W, you can directly plug the 300W inverter plug into the cigarette lighter socket for use. The inverter with more than 300 watts is directly connected to the battery through the alligator clip wire. The red wire is connected to the positive pole of the battery, and the black wire is connected to the negative pole of the battery (do not connect it reversely, remember!) If the power supply site 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 AC should be longer.

7. Q: What is the danger of using inverter?

Answer: The wire from the car battery to the inverter input terminal carries a very large current. If the wire is of poor quality, too thin or the load exceeds the standard, causing the copper wire to heat up or even eventually catch fire, it will lead to a very serious accident. Therefore, the inverter must be operated in strict accordance with the provisions of the user manual during its use

8. Q: How do I know the capacity of the battery?

A: There are many letters and numbers printed on the battery. If you find the words XXAH, you can know how large the battery is. Let’s start with the meaning of AH. A stands for ampere (amp.), that is, the unit of current, and H stands for hour. The two letters together mean “ampere hour”, that is, how many amperes of current can be continuously output in one hour. The preceding XX is usually two numbers, that is, the number of amperes. For example, 45AH means that the battery can output (12V) 45A current in an hour. As for the output power of this battery, we multiply 12V by 45A to get 540W, which is the output power (theoretical value) of this battery.

9. Q: How to equip a proper inverter for the battery?

Answer: If the specification of the battery is 12V 50Ah, we multiply 12V by 50Ah, and the output power of the battery is 600W. If the efficiency of the inverter is 90%, we multiply 90% by 600 watts to get 540 watts. This means that your battery can drive an inverter with a maximum output power of 540 watts. Of course, you can also buy an inverter with an output power of 800W, regardless of the current battery specifications. Then, first use the battery within the allowable range, and then use it at full power after a larger car is replaced in the future. Finally, the power requirement of the inverter is not high. For example, 100 watts is enough. You can buy a low-power inverter. In addition, when determining the power of the inverter, there is also an important principle, that is, when using the inverter, do not operate with full load for a long time, otherwise the life of the inverter will be greatly shortened, and the fault rate of the inverter will also be significantly increased. We strongly recommend that the user should use the inverter under the condition of not exceeding 85% of the rated power

10. Q: What should be paid attention to when using the on-board inverter?

Answer: First of all, use the inverter in strict accordance with the provisions of the user manual; Secondly, the output voltage of the inverter is 220 V AC, which is in a small space and in a movable state, so be careful. Keep it in a safe place (especially away from children!), To prevent electric shock. It is better to cut off the input power when not in use. Third, do not place the inverter near the outlet of the direct sunlight or the heater. The working environment temperature of the inverter should not exceed 40 ℃. Fourth, the inverter will generate heat when working, so do not place objects near or on it. Fifth, the inverter is afraid of water, so do not make it rain or sprinkle water.

11. Question: Why is the displayed voltage lower than 220V when measuring the AC output of the quasi sine wave inverter with an ordinary multimeter?

Answer: This is normal, because when measuring the quasi sine wave AC voltage, a multimeter with the “true RMS” gear should be used to obtain the correct reading.
