  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. 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 ...

  5. 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 ...

  6. Electrical grid - Wikipedia

    en.wikipedia.org/wiki/Electrical_grid

    A super grid or supergrid is a wide-area transmission network that is intended to make possible the trade of high volumes of electricity across great distances. It is sometimes also referred to as a mega grid. Super grids can support a global energy transition by smoothing local fluctuations of wind energy and solar energy.

  7. Stand-alone power system - Wikipedia

    en.wikipedia.org/wiki/Stand-alone_power_system

    An inverter is used to generate AC low voltage, which more typical appliances can be used with. A typical stand-alone solar PV system at a sewage treatment plant in Santuari de Lluc , Spain Stand-alone photovoltaic power systems are independent of the utility grid and may use solar panels only or may be used in conjunction with a diesel ...

  8. Balance of system - Wikipedia

    en.wikipedia.org/wiki/Balance_of_system

    The balance of system (BOS) encompasses all components of a photovoltaic system other than the photovoltaic panels. [1] This includes wiring, switches, a mounting system, one or many solar inverters, a battery bank and battery charger.

  9. Mains electricity by country - Wikipedia

    en.wikipedia.org/wiki/Mains_electricity_by_country

    (1) Nominal grid voltage according to regulation is 230/400 V, [46] but in practice, equipment with 220/380 V is more commonly used. (2) Types C and F plugs are officially recognized by SNI 04-3892.1.1-2003. (3) British type G sockets are common in Riau Islands due to their close proximity to Singapore. [47] Iran: C, F 220 V 400 V 50 Hz Iraq
