Product Information

SINACON PV inverter

Centerpiece of the photovoltaic balance of plant

Siemens' electrical Balance of Plant (eBoP) solution for utility-scale photovoltaic power plants enables PV power to be reliably integrated into the grid.

Practical, economical, and time-saving: The MV-inverter station is a comprehensive plug-and-play solution with highest power density for extra-large PV plants.
In the station, three high-performance components from the Siemens portfolio work together perfectly: central inverter, transformer, and RMU (Ring Main Unit).

FITformerREN – liquid immersed distribution transformer

Rugged and reliable

Step-up transformers connect PV plants to the grid. The transformers are configured to withstand high temperatures and harsh weather conditions. A special multiple winding design of the transformer enables to connect two independent PV inverters (up to 2.5 MVA) to the grid. It allows a cost-efficient solution with a large transformer (up to 5 MVA).

Function:        To convert LV to MV with identical frequency
Ratings:           < 30 MVA (< 5 MVA for PV applications), < 72.5 kV
Frequency:     50 Hz, 60 Hz
Cooling:          ONAN up to KFAF

Main advantages of FITformer REN:

  • Hermetically sealed tank leads to minimal mainentenance
  • Usage of biodegradable cooling fluids raise the flame point
  • Extremely low noise levels and losses
