How does a solar farm connect to the grid?
All solar farms connect to a specific point on the electrical grid, the vast network of wires that connects every power generation plant to every home and business that consumes power. That point is called the “point of interconnection,” or POI.
How solar inverter is connected to the grid?
The grid connect inverter converts the DC electricity produced by the solar panels into 240V AC electricity, which can then be used by the property/household. If a grid connect system is producing more power than is being consumed, the surplus is fed into the mains power grid.

The DC energy for each hour is calculated from the PV system DC rating and the incident solar radiation and then corrected for the PV cell temperature. The AC energy for each hour is calculated by multiplying the DC energy by the overall DC-to-AC derate factor and adjusting for inverter efficiency as a function of load.
