What is the inverter with the grid?
The grid inverter is a type of power inverter that takes direct current (DC), usually from solar panels or wind turbines, and converts it to an alternating current (AC). What the changing converter with grid differs from other types of power inverters is that it is tied to the mains, allowing the excess current of AC back to the grid and sold to the commercial company. In order to feed the electricity inverter back into the power grid, it must have the same electrical frequency to supply the same electrical frequency, it must also call it an inverter or an asynchronous inverter. This frequency is usually 50 or 60 cycles per second, also known as Hertz. The grid inverter must also use an oscillator to ensure that it does not create a higher voltage than the power grille allows; However, the tension must be slightly higher than what the grid releases. The modern grid converter uses integrated circuits to dynamic output voltage to match the power grid.
Many countries allow people with electrical systems that use a converter with a grid to sell their excess energy back to the energy company, although not all tools are obliged to allow it. In most cases, a system called Pure Measure is used so that a person with excess energy receives direct compensation for a net electricity amount that returns to the grid. When the power flows from the building back to the grid, the power meter turns backwards. According to a contract between energy producer and company company, the tariff may be used in the supply. The national electrical code (NEC) regulates the design and use of the grid inverter in the United States.
A modern converter with a grid can use a high -frequency transformer to convert the current. This type of transformer passes through strong steps to convert DC power to high -frequency AC, back to DC and then back to AC at the desired output voltage. This design requires computer checkAbove the transfer process, but results in less energy loss.
Some grid inverters do not use the transformer at all, which significantly reduces its weight and increases its efficiency. However, this design does not work well with a converter that has negative ground. The inverters of the grids that do not use the transformer are the most common in Europe because they do not require grid converters to have negative ground until 2005.
