2. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   Grid-tie inverters are designed to disconnect quickly from the grid if the utility grid goes down. In the United States, there is an NEC requirement [2] that in the event of a blackout, the grid tie inverter shut down to prevent the electricity it generates from harming persons repairing the power grid. Properly configured, a grid tie inverter ...

3. Grid-tied electrical system - Wikipedia

   en.wikipedia.org/wiki/Grid-tied_electrical_system

   A grid-tied electrical system, also called tied to grid or grid tie system, is a semi-autonomous electrical generation or grid energy storage system which links to the mains to feed excess capacity back to the local mains electrical grid. When insufficient electricity is available, electricity drawn from the mains grid can make up the shortfall ...

5. Islanding - Wikipedia

   en.wikipedia.org/wiki/Islanding

   Following the 2019 California power shutoffs, there was a rise in interest in the possibility of operating a house's electrical grid as an island.While typical distributed generation systems are too small to power all appliances in a home simultaneously, it is possible for them to manage critical household power needs through traditional load-frequency control.

   en.wikipedia.org/.../String_inverter

   Now high-DC-voltage "grid-tie string inverters" are all the rage for use in wind systems, too. So, string or no string, the bottom line is that the budding homebrew power industry is getting hip to high voltage as a means of improving system and inverter efficiency and lowering the costs of getting the power from one place (the roof or tower ...

8. Electrical grid - Wikipedia

   en.wikipedia.org/wiki/Electrical_grid

   Energy from fossil or nuclear power plants and renewable sources is stored for use by customers. Simplified grid energy flow over the course of a day. Grid energy storage (also called large-scale energy storage) is a collection of methods used for energy storage on a large scale within an electrical power grid.

9. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Grid-tied inverters are designed to feed into the electric power distribution system. [14] They transfer synchronously with the line and have as little harmonic content as possible. They also need a means of detecting the presence of utility power for safety reasons, so as not to continue to dangerously feed power to the grid during a power outage.
