What is inverter

图片
The pure sine inverter 3000w is also called the power regulator, which can be divided into two types: independent power supply and grid connected. According to the waveform modulation method can be divided into square wave inverter, step wave inverter, pure sine inverter 3000wand combined three-phase inverter. For the inverter used in the grid connected system, it can be divided into transformer type inverter and inverter without transformer. The pure sine wave inverter 3000w is a kind of power adjusting device which is composed of semiconductor device, mainly used to convert DC power into AC power. Generally consists of a boost circuit and an inverter bridge circuit. The boost circuit raises the DC voltage of the solar cell to the voltage required by the output of the pure sine wave inverter 3000w, and the inverter bridge circuit converts the boosted DC voltage to the common frequency AC voltage. The inverter is mainly composed of switching elements such as transistors, so that t

Other protection function of solar MPPT charge controller

1. Solar MPPT charge controller  input and output short circuit protection function. The input and output circuits of the controller should be provided with short circuit protection circuit. 2.Anti reverse charge protection function. The  solar MPPT controller  must have the protection function to prevent charging back to the solar cell from the battery. 3.Polarity reverse protection function. The solar cell component or battery is connected with the controller, and when the polarity is reversed, the controller should have the function of protecting the circuit. 4.Lightning protection function. The input end of the controller is provided with a lightning protection function, and the type and the rated value of the arrester shall ensure that the expected impact energy can be absorbed. 5.Anti impulse voltage and impulse curren protection. The controller should not be damaged by applying 1.25 times nominal voltage at the input of the controller for an hour. The controller charging circui

Do solar panels produce radiation?

The advantages of solar power is obvious, but there is always a misunderstanding of everyone. Do solar panels produce radiation? Solar power generation convert solar energy directly into DC power through the characteristics of semiconductor, into direct current power, and then convert DC power into alternating current which can be used by load. There is no chemical change and nuclear reaction, so solar power will not have short wave radiation. While the  commercial solar inverter  is just a common electronic products, althrough there is the IGBT or a transistor inside, only with dozens of switching frequency, but all the solar inverters have a metal shell, which can greatly shield the radiation, and in accordance with the provisions of the global electromagnetic compatibility certification. What is radiation? The meaning of radiation is very broad, light radiation, electromagnetic radiation, particle flow is radiation, heat is radiation. So it is clear that we are in a variety o

Home solar power system change the rural areas

The rise of home solar power system in the rural areas, not only bring a stable income to the farmers, but also use rural areas resources effectively. Let barren hills, courtyards and roofs are used properly. It is precisely because of these strong conditions, so that home solar power system in rural areas has great development potential. 1.Effectively improve the living environment of rural areas Macroscopically, the photovoltaic industry has a great significance to optimize the structure of energy consumption, solve the contradiction between energy supply and demand, promote energy conservation and emission reduction, and protect the environment. Microscopically, solar power generation from the construction to the grid generation, there is no waste and no energy consumption, but also can continue to generate electricity. Solar power projects in rural areas will be more effective in promoting energy-saving emission reduction, will guide more families to use new energy sources, so

MPPT algorithm of high efficiency and energy saving solar inverter

图片
The biggest highlight of SOROTEC  solar panel inverter  is its advanced MPPT algorithm, this algorithm can ensure the solar tracking efficiency of 99%. SOROTEC solar inverter applications is the ideal solution for a variety of occasions, such as water supply and demand for irrigation, desert control, green space, livestock and residential housing. Different from the traditional solar inverter, SOROTEC  solar system inverter  has a friendly user experience and a variety of protection performance. The solar inverter can be automatically turned on after connecting to the solar panel without any parameter setting. In addition, it also has the function of over voltage protection, reverse connection warning and high temperature protection. After the visit of SOROTEC’s booth, many customers have changed the concept of solar inverter. Before customers know SOROTEC’s products, generally uses the motor to generate power and the motor fuel consumption is very high, the high cost resulting in

The role of UPS for data center and its energy consumption analysis

The power supply of the data center can not be interrupted for a moment, even if only a few seconds interruption may also cause significant data loss or damage to the equipment, and even affect the normal operation of the data center, causing serious economic losses. With the rapid development of information technology and related industries, data center UPS power supply system has become a reliable guarantee for the operation of data center. With the development of industry and the wide application of computer technology, more and more data centers need to be protected by data center UPS power supply system. For the data center,  modular UPS system  is not only as a whole product to continue supplying power to the load after power failure, but as a high reliability and high intelligent power supply platform, comprehensive protection for the entire data center, not only can provide the backup time, also can improve the quality of power grid. Therefore, data center UPS as an importan

Technological innovation of solar inverter companies

With the deterioration of the climate, renewable energy development has become the mainstream of the world. With policy guidance, government subsidy and capital investment, solar energy and other new energy companies are developing rapidly. But compared with conventional energy, under the competition of cost and technology, the survival of the fittest solar inverter companies also entered the accelerated phase. The  solar energy inverter  which is the key equipment of solar power plant as an example, related enterprises in 2012 Chinese market up to 300, while it is reduced to about 100 in 2015, and only more than and 10 active solar inverter companies in 2016. 2015, Chinese solar energy installed capacity exceeded Germany became the world’s first. At the same time, the transformation is happening quietly: subsidies backslide forced the technical innovation of enterprises to achieve cost breakthrough, then implement of solar “leader” plan to promote technological upgrading of enterp

Some advantages of low frequency UPS and high frequency UPS

图片
Technology is always in the development and has now entered the digital age, the new technology to replace the old technology is the law of history, the level of competition increased significantly, which is also true in UPS power supply industry. Advantages of high frequency UPS 1.Low power consumption In the same index, such as the input power factor is above 0.95, the UPS must be applied in low frequency harmonic filter or changed to 12 pulse rectifier, that is to increase a device in the front, coupled with the output transformer, two more links than  high frequency UPS . Due to the influence above, the efficiency of the  low frequency UPS  is 5% lower than that of the high frequency UPS. In the same capacity of 100kW, low frequency UPS consume more 50 thousand kwh of electricity each year than the high-frequency UPS! This has far-reaching significance in energy saving and emission reduction today. 2.High input power factor Low frequency UPS is generally below the input ci
