The operating conditions of the transformer connected to the inverter are particularly unknown for each solar power plant; thus, the transformer will be subject to a particular harmonic content
For e.g. if the 120/208V electrical panel is not able to use up the generated PV output and the power is back-fed into the 575V distribution equipment, then would the power be used by other panels or distribution equipment tapped into this 575V distribution equipment? or would it be fed back into the grid?
Because solar transformers operate at a steady voltage, with the rated voltage controlled by inverters, voltage and load fluctuations are considerably lower than in wind turbines. Solar-power systems also have special design issues. Because the largest solar inverter size is about 500 kilovolt Ampère (kVA), designers are building 1,000 kVA
Simple example, if a transformer could handle 20 amps of load and the solar panels can generate 21 amps of power the transformer would overload in reverse. Basically that, really it''s the sustained synchronized nature of solar. They might put a 100kVA transformer for 6 houses with 200A service. This only really handles 400A combined.

Transmission of power and voltage conversion 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.
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.
The solar step-up transformers are generally supplied as combined transformers (pad-mounted transformers) or pre-assembled substations (European transformers) as complete units. What faults can occur in solar powerfarm operation?
