The off-grid inverter is an inverter used in off-grid solar power generation systems. Its main function is to convert the direct current generated by solar panels into alternating current to meet the power demand in off-grid environments, such as in remote areas, In camping, boats, or moving vehicles. off grid solar inverter,off grid 3 phase inverter, off grid solar power inverter, off grid solar inverter 5kw, off grid solar inverters for sale Ningbo Autrends International Trade Co., Ltd. , https://www.china-energystorage.com
"The package of COB has high requirements on the electrical parameters and packaging requirements of LED chips. Previously, COB had some problems in terms of package form, heat dissipation and light efficiency. Now these problems are being gradually solved, and the secondary application of COB is relative to Other packages are much simpler." Zheng Xiaoming, general manager of Star Spectrum Optoelectronics, said that COB light sources have been used in commercial lighting and industrial lighting applications, and various bulb and spotlight markets are gradually being introduced. The perfection of COB light source requires a development process, but it will certainly become one of the mainstream packaging forms of the future LED market.
In the first half of this year, Starlight Optoelectronics actively responded to market changes, adjusted product mix, and gradually increased the proportion of testing and sorting equipment for COB packaging and application. Due to the individualized design of the COB light source, many custom equipment appeared in the orders of Star Optoelectronics in the first half of the year. "Customer requirements are diversified, and we must fully meet the different needs of our customers." Zheng Xiaoming said.
Although the LED market is not optimistic in the first half of the year, Zheng Xiaoming is still optimistic about the trend in the second half of the year. "It will definitely be better than last year." He revealed that in the second half of this year, the research and development and production focus of Starpower Optoelectronics is the standard test and online of various COBs. Test equipment, including line test equipment, will greatly improve equipment reliability, repeatability and comparability.
Because the COB light source has very high heat dissipation requirements, Star Spectrum Optoelectronics has put forward the concept of comprehensive thermal testing and photoelectric index testing of the equipment, so that it can measure the junction temperature, thermal resistance and voltage coefficient K of the LED very accurately, and test the LED. The luminosity and chromaticity parameters at different junction temperatures, and can also measure the junction temperature of the LED luminaire under operating conditions.
Zheng Xiaoming said that the company will fully display the company's COB test equipment at the 2012 High-tech LED Exhibition, which opened on August 17.
2012 High-tech LED Exhibition Exhibition Address: Guangzhou Poly World Trade Center Expo Booth No.: 2J01

Main effect:
Converts the direct current generated by solar panels into alternating current to supply the power needs of homes, mobile devices, or other electrical appliances.
Off-grid inverters are usually equipped with battery energy storage systems, which store excess power so that they can continue to supply power when the solar panels cannot generate enough power.
Differences from On-Grid Inverter:
Connection method: Off-grid inverter is an inverter used in the off-grid system and does not need to be connected to the grid. They are often used in places where there is no access to the grid, such as remote areas, wild camping, or outlying islands.
Grid requirements: Unlike on-grid inverters, off-grid inverters do not need to meet grid requirements and standards because they are not connected to the grid. They can operate independently and can be adapted to different off-grid environments.
Self-sufficiency: The off-grid inverter is equipped with a battery energy storage system, which can store excess electricity so that it can continue to supply electricity when the solar panels are unable to generate electricity. This makes the off-grid system self-sufficient and not dependent on an external grid for power.
Application scenarios: Off-grid inverters are widely used in remote areas, camping, ships, mobile vehicles, and some special-purpose scenarios. On the other hand, grid-connected inverters are mainly used in home, commercial, and industrial photovoltaic power generation systems connected to the grid.
In general, the main function of the off-grid inverter is to convert the direct current generated by the solar panels into alternating current to meet the power demand in the off-grid environment and achieve self-sufficiency by being equipped with a battery energy storage system. In contrast, on-grid inverters connected to the grid are mainly used to integrate solar power into the grid, realize the interaction between solar power and the grid, and comply with the requirements and standards of the grid.
Star Spectrum Optoelectronics will bring COB test equipment to the 2012 High Tech LED Show
With the rapid increase in the personalized demand for LED light sources for commercial lighting, the domestic COB package light source is gradually gaining market recognition since the second half of last year.
