Superior stack design
SMA Design Reserve of 38% ensures higher availability and a longer service life
The SMA Sunny Central 2500-EV and 2500-EV-US inverters are designed specifically for 1,500V PV power plants. Their stack design features 2x 1,200V IGBTs connected in series. Other inverters used for 1,500V DC voltages are often equipped with only one 1,700V IGBT. With a voltage reserve of 900 V, SMA thus offers a Design Reserve of 38% that meets availability and service life requirements to accomplish true 1,500 V DC systems.
Benefits of the stack design:
- Tried-and-tested, robust stack topology for availabilities of more than 99% over 25 years
- Up to 100% curtailment to guarantee all operating points
- Unrestricted continuous operation possible at high DC voltages of up to 1,425 V DC
