The inverter supports different firmware versions to fulfill different grid-
connection requirements within the EU.
With the firmware version ≤ 2.99.99.R, the inverter fulfills the grid-connection requirements
valid until April 26, 2019 within the EU. Grid-connection requirements outside the EU are not
affected and remain valid. With the firmware version ≥ 3.00.00.R, the inverter fulfills the
European grid-connection requirements in accordance with Regulation (EU) 2016/631 for
establishing a network code (also known as RfG), valid from April 26 2019 within the EU. The
inverter can be equipped ex-factory with the firmware version ≥ 3.00.00.R. This can be
identified by the imprints "SMA Grid Guard 10.0" and "RfG Firmware for EU countries" on the
box label. If no imprints can be found on the box label, the inverter is equipped with the
firmware version ≤ 2.99.99.R.
• Ensure that the inverter is equipped with a firmware version that fulfills the local grid-
connection requirements.
