Grid-connected inverter and off-grid inverter can be used at the same time
An inverter refers to a device that converts DC power (such as a storage battery) into AC power (usually 220V, 50Hz sine wave). It is composed of an inverter bridge, control logic, and filter circuit. Inverters are widely used in air conditioners, home theaters, electric grinding wheels,. On-grid inverters are also called grid tie inverters, which are generally divided into solar PV power generation grid tie solar inverters, wind power generation grid tie inverters, power equipment generation grid tie inverters, and other equipment generation grid tie. Sometimes, an on-grid inverter can be used directly as an off-grid inverter. The grid tie inverter sends energy directly to the grid, so the frequency and phase of the grid must be tracked. It is equivalent to a current source. Of course, there are also some inverters that. The off-grid PV inverter can work independently after leaving the grid, which is equivalent to forming an independent small grid. It mainly. In summary, the primary difference between on-grid and off-grid inverters lies in their operational context and functionality. On-grid solar inverters are tailored for grid.
