How to buy a car inverter? Which brand of car inverter is better

1.Vehicle inverter is also called automotive power converter, because the market demand for vehicle inverter is large, and the manufacturing threshold is low, so there are many small manufacturers in the production of vehicle inverter, which leads to a variety of vehicle inverter brands and uneven quality. The well-known on-board inverter brands mainly include MIG, Belkin, Olashuer, etc.

2.An inverter converts low-voltage direct current into 220 volts alternating current electronics. Normally, the on-board inverter is a 12V to 220V electronic product. Many on-board inverter products on the market are also integrated"Car charger"features.

For example, the MIG car inverter mentioned above also has the function of 12V to 5V, so it can be used as an on-board charger. (Note: The voltage of the mobile phone is 5V).

3.When choosing an inverter, consider the brand and its quality, and see if it has various protection functions to ensure the safety of the car battery and external appliances. The power of the on-board inverter is best to choose 200W or 300W.

It is best to pay attention to the waveform of the inverter, and it is best to choose a sine wave or the latest type of inverter with a modified sine waveform, because the square wave converter will cause unstable power supply and may damage the electrical appliances used. On-board inverters must have circuit protection functions.

4.Generally, the ordinary car charger** is about 50 yuan-80 yuan, and the car inverter** is higher than the ordinary car charger**. It is recommended to buy ** on-board inverter products around 200 yuan - 300 yuan.

The landlord bought a car inverter: it was plugged into a cigarette port, or it was directly connected to the battery. If you plug in the cigarette port to buy less than 200W, because the current of the car is not very large, 10-20A, too high power will burn the fuse.

The direct battery depends on its actual output power, protection function (reverse connection, short circuit, overvoltage, undervoltage, overcurrent, overload, vulnerability, temperature control) and other protection. It also depends on whether the components inside are refurbished or brand new. And so on, I hope it will help the landlord.

Take the on-board inverter as an example:

First of all,Choose from the output waveform of the inverter, preferably not lower than the quasi-sine wave;

Secondly,The inverter should have a complete circuit protection function;

Fourth,The circuits and products have been tested over time.

When the power inverter is in use, if there is a shutdown and alarm phenomenon, the following items should be checked:

1. Whether the power of the electrical appliance driven exceeds the rated power value of the inverter.

2. Whether the power inverter is well connected with the battery and electrical appliances.

3. Stop the machine during use, whether it is a temperature alarm, and you can continue to use it after stopping for a period of time.

When using a power inverter, pay attention to the voltage value of the battery-powered system, and read the manual carefully before use.

Household choose household, industrial choose industrial, household cheap, industrial expensive, and then it depends on what you do, about how much power!

There are many factors to consider when choosing an inverter, primarily power, but also output surge rating, input voltage, battery charger, and waveform.

The selection of inverter should first consider having sufficient rated capacity to meet the requirements of the equipment for electrical power under maximum load. For inverters with a single device as the load, the selection of its rated capacity is relatively simple. When the electrical equipment is a pure resistive load or the power factor is greater than that, the rated capacity of the inverter can be selected as multiple of the capacity of the electrical equipment.

At the same time, the inverter should also have the ability to resist capacitive and inductive load shocks. For general inductive loads, such as motors, refrigerators, air conditioners, washing machines, high-power water pumps, etc., when starting, its instantaneous power may be 5 6 times of its rated power, at this time, the inverter will withstand a large instantaneous surge. For such systems, the rated capacity of the inverter should have sufficient margin to ensure that the load can be started reliably, and the high-performance inverter can be started at full load for many times in a row without damaging the power components.

For the sake of their own safety, small inverters sometimes need to use soft start or current limiting start.

The inverter should also have a certain overload capacity, when the input voltage and output power are rated values, and the ambient temperature is 25, the continuous and reliable working time of the inverter should not be less than 4h; When the input voltage is rated and the output power is 125% of the rated value, the safe working time of the inverter should not be less than lmin; When the input voltage is rated and the output power is 150% of the rated value, the safe working time of the inverter should not be less than LOS

The consumption of the battery on the vehicle will be very high, the battery will not last long, and most vehicles will be able to charge the battery after several hours of driving. If the run-off is significant, the plug-in AC power source will charge the battery much faster than the alternator's ability to charge the battery. Some of the more expensive models come with a 150-amp charger, which is even more than the power of the car's charging system.

It is also necessary to determine the form of the inverter waveform, and the inverter with pure sine wave can make the precise equipment operate normally. A TV or a test device with a display, such as a mobile device, will get a bar of interference that will not produce a sine wave output from the inverter. Some portable refrigerators and air conditioners require a sine wave to start the compressor.

Modified sine waves typically have the same advantages as higher surge ratings for sine wave inverters. So, if a high surge is required, look for a modified wave inverter.
