When choosing the household inverter, how to grasp the power of the household inverter is a problem that needs to be carefully considered, in which seven types of electrical appliances need to refer to the following configuration requirements when choosing the power the household inverter.

1. Electric heating wire and pure resistive appliances such as light bulbs and solar lamps.

How much power is marked on these appliances, divide its power by 0.9, for example, 100W light bulb, 100 divided by 0.9 equals 111, equipped with a 120W power inverter can be safely used.

2. TV

There are two kinds of TV, one is liquid crystal, the other is the picture tube. For LCD TV, as long as the power of the inverter is 2 times larger than the target power of the TV. For example, LCD TV standard 100W, equipped with a 300W inverter can definitely be used. For the TV set of the picture tube, because of the large capacitance, the degaussing coil is equivalent to an inductive load, and the impact force is very strong, which is generally calculated as 10 times the peak value. For example, 100W, peak 1000W, must be equipped with more than 500W power inverter can be driven.

3. Computer.

LCD computer, according to the purchase of LCD TV point plus 90W power selection (computer host power), if it is a picture tube, according to the nominal power of the selected display to calculate its peak power plus 90W (the host power is generally less than 90W). Of course, you can also directly use the 500W inverter, absolutely no problem.

4. Electric drill.

Calculated according to 3 times the peak, for example, 500W, peak 1500W with 800W inverter, 1500W with 3000W inverter

5. Air conditioning.

The non-frequency conversion air conditioner is calculated as 7 times the peak value, and the frequency conversion air conditioner is calculated as 4 times the peak value. For example, for an air conditioner of 1000W per hour, seven times is 7000W and the peak of 3500W inverter is just 7000W. If the frequency conversion is calculated by 4 times, the peak value of 1000W peak 400050 2000W inverter is just 4000W, so the frequency conversion also uses 2000W.

6. Low-power electrical appliances.

Generally, there is no need to think too much about it, because the market price of a 100W inverter is only 70 yuan. General household appliances such as televisions, computers, stereos, and fluorescent tubes can be equipped with a 500W power inverter.

7. Special-purpose household appliances

The so-called special-purpose electrical appliances, such as juicers, blenders, impact drills, air conditioners, refrigerators and so on, are very difficult to choose, and the power of the inverter is 3-7 times that of the electrical appliances.

The combination of high-power inverter control and parallel technology effectively improves the safety of inverter control. At the same time of expanding the power supply capacity, the power supply modularization of the high-power inverter parallel system is realized. Secondly, the parallel inverter technology realizes the independence of the inverter unit, which effectively solves the problem that if one of the inverter units has a problem, the other inverter units can not operate normally.
