On-Grid Inverter converts DC power to AC power for feeding back to the grid. The frequency of the output voltage of the grid-connected inverter needs to be the same as the grid frequency (50 or 60Hz), which is generally achieved by the oscillator in the machine, and the output voltage will also be limited not to exceed the grid voltage. Modern high-quality grid-connected inverters can have an output power factor of 1, which means that the output voltage and current phases are the same, and the phase difference between them and the grid voltage is within 1 degree. There is a microprocessor in the inverter that can sense the AC waveform of the grid, and according to this waveform, generate voltage and send it back to the grid. However, the electricity sent back to the grid needs to have a certain proportion of reactive power, so that the power of the nearby grid is within the allowable limit. noon) its voltage may rise too high. on grid solar inverter, micro inverter on grid, 25 kw on grid inverter, on grid power inverter, 15kw on grid inverter Ningbo Autrends International Trade Co., Ltd. , https://www.aitsolarpanels.com
The company said that the main influencing factors of the performance growth are: the construction of investment projects and the deep development of international high-end customers, which strongly supported the company's business development; the technological innovation of intelligent terminal products continued to accelerate, and the market scale continued to expand, driving micro-electricity. The rapid development of the sound industry.
The operating results disclosed in this performance report are not different from the expected results in the company's 2012 third quarter report. 
If the power of the grid is cut off, the grid-connected inverter needs to be disconnected from the grid quickly. This is a regulation of the National Electrical Code (NEC) in the United States to ensure that when the grid is out of power, the grid-connected inverter will not provide power to the grid, and at this time the workers who maintain the grid will not be electrocuted.
Properly configured, grid-tie inverters allow a home to use alternative energy sources that it generates itself (such as solar or wind power) without cumbersome wiring and without the need for batteries. If there is insufficient alternative energy, the insufficient part will still be provided by electricity from the grid.
Grid-connected inverters are widely used in household photovoltaic power generation systems, commercial and industrial photovoltaic power plants and other scenarios. By connecting to the grid, they help to achieve efficient use of renewable energy and reduce carbon emissions, promoting sustainable development and popularization of clean energy.
