2. Stand-alone power system - Wikipedia

   en.wikipedia.org/wiki/Stand-alone_power_system

   Schematics of a hybrid system. A stand-alone power system (SAPS or SPS), also known as remote area power supply (RAPS), is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system. Typical SAPS include one or more methods of electricity generation, energy storage, and regulation.

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. [1]

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. Uninterruptible power supply - Wikipedia

   en.wikipedia.org/wiki/Uninterruptible_power_supply

   A solar inverter, or PV inverter, or solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

6. 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.

7. Synchronization (alternating current) - Wikipedia

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

   In an alternating current (AC) electric power system, synchronization is the process of matching the frequency, phase and voltage of a generator or other source to an electrical grid in order to transfer power. If two unconnected segments of a grid are to be connected to each other, they cannot safely exchange AC power until they are synchronized.
