[Rocklin, CA] Developed for integration with its Sunny Central line of central inverters for utility-scale PV plants, SMA’s redesigned Medium Voltage Block includes a medium-voltage transformer, an ac busbar kit and an optional tracker auxiliary rack. The block’s layout is based on that of a traditional ANSI pad-mount transformer, with low-voltage connections positioned horizontally in plane with the output busbars of the inverter. All the necessary hardware for installation, including the busway, busbars, grounding straps, connection hardware and transformer monitoring cable sets, are included. Transformer monitoring, communicated through the inverter MODBUS registries, reports the status of the transformer, including values for temperature and pressure, which enables trend-based predictive maintenance to streamline O&M activities.
