What do you know about the household inverter?

household inverter refers to the lifting device that converts low-voltage DC (12V / 24V and other voltage batteries) into AC (AC220V). Its function is mainly to meet the emergency use of refrigerators, computers, televisions, induction furnaces, air conditioners, lighting, and other electrical equipment in case of power failure. AC power supply (AC220V) is adopted for household appliances, and the battery is a low-voltage DC power supply, which cannot be directly used for household appliances. Power shall be supplied by an AC inverter.

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

It is mainly divided into sine wave household inverters and domestic square wave household inverters.

one The sine wave AC generated by domestic sine wave household inverters is the same as or even better than the power grid we use every day because it has no electromagnetic pollution in the power grid.

two The output of domestic square wave household inverters is a kind of square wave AC with poor quality and its positive and negative maximum values are generated almost at the same time, which has a serious unstable impact on the load and the domestic inverter itself. At the same time, its load capacity is low, only 40% ~ 60% of the rated load, and can not bear the induced load. If the load is too large, the third harmonic component in the square wave current will increase the capacitive current in the load, and in serious cases, it will damage the power filter capacitance of the load.

What is the latest development trend of the household inverter?

Given the above shortcomings, quasi sine wave (or improved sine wave, improved sine wave, analog sine wave, etc.) household inverters have appeared in recent years. There is a period between the positive maximum and the negative maximum of the output waveform. At the same time, the utilization effect is improved, but the waveform of the quasi sine wave is still composed of broken lines, which belong to the category of square wave and have poor continuity.

How to choose household inverter products?

The household inverter is a kind of power supply product working in a high current and high-frequency environment, and its potential failure rate is high. Therefore, consumers must be careful when buying.

Firstly, select from the output waveform of the domestic inverter, preferably not lower than quasi sine wave;

Secondly, the household inverter should have a complete circuit protection function;

Third, the manufacturer must have a good after-sales service commitment;

Fourth, the circuit and products were tested for some time.

We have to choose the household inverters that suit us according to different needs to play the best role. Shenzhen Sumry Electronics Co., Ltd. always focuses on customers’ needs and therefore it will provide the best household inverters for all customers from all over the world.
