Power selection skills of household inverters

When choosing a household inverter, how to grasp the power of the household inverter is a problem that needs to be carefully considered. Among them, there are mainly seven types of electrical appliances. When choosing the power of a household inverter, you need to refer to the following configuration Require.

1. Pure resistive electrical appliances such as heating wire and light bulbs, solar lights, etc.

The power of these appliances is divided by 0.9. For example, for a 100W bulb, 100 divided by 0.9 equals 111. It can be safely used with a 120W inverter.

2. TV

There are two types of TVs, one is liquid crystal and the other is picture tube. For LCD TVs, as long as the inverter is twice the power of the TV standard. For example: LCD TVs with a standard of 100W can definitely be used with a 300W inverter. For the television of the picture tube, due to the large capacitance, the degaussing coil is equivalent to an inductive load, and the impact force is very strong, generally calculated as 10 times the peak value. For example: 100W, the peak value is 1000W, it can be driven only with an inverter of 500W or more.

3. Computer

For computers with LCD monitors, select the LCD TV point plus 90W power (computer host power). If it is a kinescope, press the nominal power of the selected monitor to calculate its peak power plus 90W (host power is generally within 90W). Of course, a 500W inverter can also be used directly, which is absolutely no problem.

4. Electric drill

Calculated by 3 times the peak value, for example: 500W, peak 1500W with 800W inverter, 1500W, with 3000W inverter.

5. Air conditioning

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

6. Low-power electrical appliances

Generally, there is no need to think too much, because a 100W inverter is only sold for 70 yuan in the market. General household appliances such as TVs, computers, stereos, and fluorescent tubes can be equipped with a 500W.

7. Household appliances for special purposes

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