Utility scale photovoltaic (PV) systems are connected to the network at medium or high voltage levels. To step up the output voltage of the inverter to such levels, a transformer is employed at its output.
Before untangling more puzzling windings decisions for isolation transformers, transformers with energy storage in microgrid scenarios, or PV systems supplying both three-phase and single-phase dedicated loads, let us consider a common case: a grid-tied PV system.
In this paper, the author describes the key parameters to be considered for the selection of inverter transformers, along with various recommendations based on lessons learnt. This should enable the user to avoid potential pitfalls and failures while designing future utility scale.
Israel has made significant strides in expanding its renewable energy sector in 2024. The country installed 900 MW of photovoltaic (PV) capacity and 11 MW of biogas capacity, marking a decrease of about 200 MW compared to the 1.

Inverter transformers are used in solar parks for stepping up the AC voltage output (208-690 V) from solar inverters (rating 500-2000 kVA) to MV voltages (11-33 kV) to feed the collector transformer. Transformer ratings up to 5 MVA are with double LVs and up to 16 MVA are.
