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.
What is a Grid-Tied Inverter?
From a higher potential to a lower potential, the current flows. The grid-connected solar inverter attempts to keep its output voltage greater than the grid voltage. Net current flow from solar

OverviewOperationPayment for injected powerTypesDatasheetsExternal links
Grid-tie inverters convert DC electrical power into AC power suitable for injecting into the electric utility company grid. The grid tie inverter (GTI) must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant. 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
