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. In DC, electricity is maintained at constant voltage in one direction. Anti-islanding protection prevents backfeeding during outages. Smart inverters enable two-way grid communication and support. . Grid-Following Inverters (GFLI) and Grid-Forming Inverters (GFMI) are two basic categories of grid-connected inverters.
