2. Inverter-based resource - Wikipedia

   en.wikipedia.org/wiki/Inverter-based_resource

   An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation ( CIG ), include the variable renewable energy generators (wind, solar) and battery storage power stations ...

3. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel , wind turbine , hydro-electric , and the grid.

4. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. [2]

5. Grid-tied electrical system - Wikipedia

   en.wikipedia.org/wiki/Grid-tied_electrical_system

   The inverter monitors the alternating current mains supply frequency and generates electricity that is phase matched to the mains. When the grid fails to accept power during a "black out", most inverters can continue to provide courtesy power.

6. Stand-alone power system - Wikipedia

   en.wikipedia.org/wiki/Stand-alone_power_system

   Storage is typically implemented as a battery bank, but other solutions exist including fuel cells. Power drawn directly from the battery will be direct current extra-low voltage (DC ELV), and this is used especially for lighting as well as for DC appliances. An inverter is used to generate AC low voltage, which more typical appliances can be ...

7. Synchronization (alternating current) - Wikipedia

   en.wikipedia.org/wiki/Synchronization...

   Connecting a generator with the wrong phase sequence will result in large, possibly damaging, currents as the system voltages are opposite to those of the generator terminal voltages. [ 2 ] The voltage, frequency and phase angle must be controlled each time a generator is to be connected to a grid.
