How to choose the power of home solar inverter?

A: When choosing a home inverter, how to grasp the power size of the home inverter is a problem that needs to be carefully considered, of which there are mainly seven types of appliances in the choice of home inverter power, you need to refer to the following configuration requirements.

1, Electric filament and light bulbs, solar lights and other purely resistive appliances

These appliances on the label how much power, with its power divided by 0.9, for example: 100W light bulb, 100 divided by 0.9 is equal to 111, equipped with a 120W inverter can be used safely.

2, TV

Television is divided into two kinds, one is liquid crystal, one is a tube. For LCD TVs, as long as the inverter is 2 times larger than the TV's marked power, it can be used. For example: LCD TV standard 100W, equipped with a 300W inverter can definitely be used. For tube TV sets, due to the capacitive large, degaussing coil is equivalent to an inductive load, the impact is very strong, generally calculated by 10 times the peak. For example: 100W, peak 1000W, to be equipped with more than 500W inverter can be driven.

3, computer

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

4, electric drill

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

5，Air conditioner

The non-inverter is counted as 7 times the peak value, and the inverter is counted as 4 times the peak value. For example, such as 1000W per hour air conditioning, 7 times is 7 is 7000W, 3500W inverter peak just 7000W. frequency conversion according to 4 times, 1000W peak 4000, 2000W inverter peak just 4000W, so the frequency conversion should also be used 2000W.

6, small power appliances

Generally do not have to think too much, because a 100W inverter market price is only 70 yuan, general household appliances such as TV, computer, audio, optical tube of these appliances, equipped with a 500W can be.

7, special-purpose household appliances

The so-called special-purpose appliances, such as juicers, blenders, impact drills, air conditioners, refrigerators and other appliances, in the choice is very difficult to select the power of the inverter if the power of the appliance is 3-7 times.

*** Note: Resistive loads: you can choose the same power as the load. Capacitive load: you can choose 2-5 times the power according to the load.
