The main use for photovoltaic transformer in large-scale solar applications is to step up inverter output voltages for the delivery of renewable energy to the utility grid. Pad-mounted distribution transformers are the most common type of distribution transformer china encountered in solar array fields. While pole-type distribution transformers are frequently the norm in conventional electric distribution systems to supply power to residences and some businesses, solar applications tend to use pad-mounted transformers because the associated ac circuits typically run underground rather than overhead.
