There are two main effects to consider when sizing transformers fed from inverters powered by PV arrays. Modern PV inverters normally put out a sinusoidal voltage and current waveform that is close to an ideal sine wave.
Inverter duty transformer: They are used to transfer electrical energy without changing the frequency. It converts DC energy into AC at a low voltage after which it increases the value to suit the devices that are being used. They are used for small power conversion.
Renewable transformers also have different voltages than the standard industrial voltages you might have seen. 800, 630, and 600 are all common voltages used with solar arrays. 800V is more common with European inverter manufacturers; 630V is usually found in larger solar arrays; and 600V is the most common voltage for solar inverters.
The transformer will need to accommodate, e.g. step down the voltage: from 480 V along the inverter circuit to provide 208 V to the utility side circuit. In this context, the transformer will be energized first from the utility side, and the inverter side second. Given our newly gained naming conventions, this arrangement is straightforward.
