As aforementioned, the inverter is interconnected to the grid, so it should fulfill the grid standards as well. These standards includes power quality, grid ride through capability and islanding prevention . Power quality is mainly measured on the basis of Power Factor (PF) and Total Harmonic Distortion (THD).
The grid-connected solar inverter operates according to a simple basic electrical theory. 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 to the grid is the result of this.
In the grid-connected inverter, the associated well-known variations can be classified in the unknown changing loads, distribution network uncertainties, and variations on the demanded reactive and active powers of the connected grid.
The grid-tie inverter enables your home to not just import power from the utility, but export power to the utility as well. When solar energy is available for usage, the inverter distributes power to your household appliances directly from the solar panel. In the instance that there is not enough solar energy, it switches back to grid power.
