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]
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 ...
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. [1]
Grid, styled "GRID," was founded during the 2001 California energy crisis by Erica Mackie, P.E., and Tim Sears, P.E., two engineering professionals. [2] According to a U.S. Environmental Protection Agency program profile, it "piloted its flagship Solar Affordable Housing Program in the San Francisco Bay Area in 2004, and subsequently expanded to other parts of the state."
A solar inverter is a balance of system (BOS) component of a photovoltaic system and can be used for both grid-connected and off-grid (standalone) systems. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti- islanding protection.

About 840 million people (mostly in Africa), which is ca. 11% of the World's population, had no access to grid electricity in 2017, down from 1.2 billion in 2010. [ 2 ] Electrical grids can be prone to malicious intrusion or attack; thus, there is a need for electric grid security .
