On the Zhalatosang Mountain in Kola Township, Yajiang County, Garze Tibetan Autonomous Prefecture, Sichuan, at an altitude of 4,600 meters, more than 1,100 builders braved the severe cold and lack of oxygen to continuously work on the construction front line of the Kola Photovoltaic Power Station.

The "water-solar hybrid" project is located in the area between 4,000 meters and 4,600 meters above sea level on the Western Sichuan Plateau. It has an installed capacity of 1 million kilowatts and a construction area of over 16 square kilometers, which is equivalent to the size of more than 2,000 standard football fields. The project consists of more than 2 million photovoltaic modules and more than 5,000 inverters, with nearly 50,000 tons of steel used for the supports.

The oxygen content on the construction site is only 50% of that in plain areas, but the ultraviolet radiation is 90% higher. During the construction period, it was necessary to "resist" strong winds with instantaneous wind strength of level 8 to level 9 from time to time, and the effective construction time was continuously compressed. Under such harsh weather conditions, workers gritted their teeth and overcame it, seizing the construction window period.

Household inverter is suitable for household appliances use inverter, can help household appliances to achieve the conversion of direct current and alternating current, we use the household inverter, the user needs to connect the wire to the household inverter, and each household inverter will have a positive and negative signs, in general the red represents the positive pole, the black represents the negative pole, in the connection of the wire the user must pay attention to observe the red wire to the red end, black wire to the black end, if you accidentally connect the wrong will cause a short circuit, and even burned household inverter, it is a good idea to connect the red wire to the black end. When connecting the wires, users must pay attention to observe that the red wire is connected to the red end and the black wire is connected to the black end, if you are not careful to connect the wrong one, it will cause the circuit to short circuit and even burn down the household inverter, so you must be careful when connecting the wires.

In fact, there are many electrical appliances in our family will use the household inverter, such as air conditioning, computers, refrigerators, hoods and other electrical appliances, they are all through the household inverter will be converted from DC to AC power required for electrical appliances.

The characteristics of household inverters are high conversion efficiency, good stability, high safety performance, in addition to commonly used household appliances, some small appliances such as fans, mobile phones, digital cameras, etc. will also use household inverters. Visible household inverter is everywhere in our life. At the end, I want to tell you that we not only need to choose the right household inverter, but also need to pay attention to the maintenance of the inverter, careful operation.
