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. These Portable Generators Are Great For On-The-Go Power Or ...

   Like most generators, inverter generators provide 120/240 volts of AC power. They generate AC current just like the others, but it’s then converted to DC (Direct Current), and then inverted back ...

4. Stand-alone power system - Wikipedia

   en.wikipedia.org/wiki/Stand-alone_power_system

   There are three basic elements to the system - the power source, the battery, and the power management center. Sources for hybrid power include wind turbines, diesel engine generators, thermoelectric generators and solar PV systems. The battery allows autonomous operation by compensating for the difference between power production and use.

5. Power electronics - Wikipedia

   Power is instantaneously drawn from onsite batteries and converted into usable AC voltage by the VSI, until grid power is restored, or until backup generators are brought online. In an online UPS system, a rectifier-DC-link-inverter is used to protect the load from transients and harmonic content.

6. 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]

7. Off-the-grid - Wikipedia

   en.wikipedia.org/wiki/Off-the-grid

   For net metering, to sell back to the grid, an inverter would still be needed, and also to use the grid-as-a-backup, if still using a grid-tied electrical system. DC electricity doesn't transmit over power lines efficiently over long distances, but if it is generated and stored in batteries on site, it is more efficient by 10-20 percent to keep ...
