To step up the output voltage of the inverter to such levels, a transformer is employed at its output. This facilitates further interconnections within the PV system before supplying power to the grid. The paper sets out various parameters associated with such transformers and the key performance indicators to be considered.
In the power system’s transmission and transform process, solar transformers played an essential role in varying the AC voltage while maintaining an AC rate constant. The transformer increases the voltage at the generator’s terminal to transmit a specific amount of power.
In the PV/Solar grid-tie applications the primary side of transformer is often incorrectly identified as the side connected to the solar inverter. In practice; the transformer will initially be energized from the side tied to the facility/utility grid. After the transformer is energized from facility/utility grid it will send power to the inverter.
The current (load) will remain idle until inverter pushes current back through the transformer to the facility/utility grid when the PV plant generates power. At this point the transformer is being used in a bi-directional application with no additional energizing inrush currents when the PV source is generating power.
If the conversion of the power produced by the solar panels is done by more than one photovoltaic inverter, it is recommended that the output of those inverters be grouped by connecting them to a secondary LV switchboard, which is then connected to the main LV switchboard at a single point.
Photovoltaic power generation is an efficient use of solar energy.
