What is a 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.
How does a grid tie inverter work?
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.
What is a grid-interactive inverter?
In the United States, grid-interactive power systems are specified in the National Electric Code (NEC), which also mandates requirements for grid-interactive inverters. Grid-tie inverters convert DC electrical power into AC power suitable for injecting into the electric utility company grid.
What is a transfer switch in a grid-tie inverter?
A transfer switch is also known as a transfer relay. Grid-tie inverters usually feature a built-in load transfer switch for backup emergency power applications. As long as utility power reaches the inverter’s AC input side, the transfer switch passes the AC grid power directly through the inverter to the load.
What is the output voltage of a grid-tie inverter?
For inverters designed for residential use, the output voltage is 120 V or 240 V at 60 Hz for North America. It is 230 V at 50 Hz for many other countries. Peak Efficiency The peak efficiency is the highest efficiency that the inverter can achieve. Most grid-tie inverters have peak efficiencies above 90%.
What are inverter specifications?
Specifications provide the values of operating parameters for a given inverter. Common specifications are discussed below. Some or all of the specifications usually appear on the inverter data sheet. Maximum AC output power This is the maximum power the inverter can supply to a load on a steady basis at a specified output voltage.
