2. 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.

3. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Utility frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.

4. 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 ...

5. Three-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Three-phase_electric_power

   A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line-to-ground voltage because it uses less conductor material to transmit a given amount of electrical power. [3] Three-phase power is mainly used directly to power large induction motors, other electric motors and other ...

6. Stand-alone power system - Wikipedia

   en.wikipedia.org/wiki/Stand-alone_power_system

   Reactive power: The circulating current can differ from the current consumed when capacitive or inductive loads are used. Harmonic distortion: Non-linear loads may create distortion of the inverter waveform. Mismatch between load and inverter size: When a higher rated inverter is used for a lower capacity load, overall efficiency is reduced. [9]

7. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   The purpose of a balanced power system is to minimize the noise coupled into sensitive equipment from the power supply. Unlike a three-wire distribution system, the grounded neutral is not distributed to the loads; only line-to-line connections at 120 V are used. A balanced power system is used only for specialized distribution in audio and ...
