2. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   A high-quality modern grid-tie inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1° of the AC power grid. The inverter has an internal computer that senses the current AC grid waveform, and outputs a voltage to correspond with the grid. However, supplying ...

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 ...

4. Soft-switching three-level inverter - Wikipedia

   en.wikipedia.org/wiki/Soft-switching_three-level...

   A soft-switching three-level inverter (S3L inverter) is a high-efficiency power electronic inverter intended, in particular, for use with three-phase drives, as a grid-tie inverter for photovoltaic installations or wind turbines and in power supplies. [1] The topology was developed in 2009 at HTWG Konstanz (Constance University of Applied ...

5. Solar inverter - Wikipedia

   en.wikipedia.org/wiki/Solar_inverter

   The key role of the grid-interactive or synchronous inverters or simply the grid-tie inverter (GTI) is to synchronize the phase, voltage, and frequency of the power line with that of the grid. [8] Solar grid-tie inverters are designed to quickly disconnect from the grid if the utility grid goes down. This is an NEC requirement that ensures that ...

6. Wikipedia:Cleanup Taskforce/String inverter - Wikipedia

   en.wikipedia.org/.../String_inverter

   The term "string inverter" is somewhat nonsensical in this context because the small-scale wind generators are not typically done in arrays like solar panels and there is typically only a single generator per installation (for small systems). Now high-DC-voltage "grid-tie string inverters" are all the rage for use in wind systems, too.

   grid energy storage Any system tied to an electrical grid that stores electrical energy at low demand times and releases it to meet peak loads; it might be a centralized station like a pumped-storage hydroelectric plant, or might be distributed over many customer sites such as by the use of electric vehicle batteries. grid-tie inverter

8. Islanding - Wikipedia

   en.wikipedia.org/wiki/Islanding

   Between those events, the inverter produces a sinusoidal output, varying the current to produce the proper voltage waveform given the previous cycle's load. When the main grid disconnects, the power factor on the island suddenly decreases, and inverter's current no longer produces the proper waveform. By the time the waveform is completed and ...

9. Interconnector - Wikipedia

   en.wikipedia.org/wiki/Interconnector

   An interconnector (also known as a DC tie in the USA [1]) is a structure which enables high voltage DC electricity to flow between electrical grids. An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids .
