System Description 11SI44M-80H-13-MC-IA-en-10
NOTICE
Damage to the enclosure seal in subfreezing conditions
If you open the product when temperatures are below freezing, the enclosure seals can be damaged. Moisture can
penetrate the product and damage it.
• Only open the product if the ambient temperature is not below -5°C.
• If a layer of ice has formed on the enclosure seal when temperatures are below freezing, remove it prior to
opening the product (e.g. by melting the ice with warm air).
NOTICE
High costs due to inappropriate Internet tariff
Depending on use, the data volume of the product transferred via the Internet may vary in size. The data volume
depends, for example, on the number of inverters in the system, the frequency of device updates, the frequency of
data transfer to SunnyPortal or the use of FTP push. High costs for the Internet connection can be the result.
• SMA Solar Technology AG recommends using an Internet flat rate.
The inverter supports different firmware versions that are suitable for different systems.
Inverters using firmware version ≤2.99.99.R are suitable for off-grid systems and systems that are not subject to
the European grid connection conditions in accordance with Regulation (EU) 2016/631 for establishing a
network code (also known as RfG). In addition, inverters with firmware version ≤2.99.99.R may be used in
systems that have been commissioned before April 27, 2019, and that are subject to the grid connection
conditions of VDE-AR-N 4105:2011-08.
Inverters using a firmware version ≥3.00.00.R are only suitable for systems that are operated in parallel with the
utility grid (e.g. SMAFlexibleStorageSystem). The firmware version ≥3.00.00.R complies with VDE-AR-N
4105-11:2018, EN50549-1:2018, C10/11:2018 and EREC G98:2018/G99:2018 of the European grid
connection conditions in accordance with Regulation (EU) 2016/631 for establishing a network code (also
known as RfG), valid from April 27, 2019 within the EU.
Inverters with a firmware version ≤2.99.99.R can be identified by the imprint 2:Off-Grid on the box label.
Invertes with a firmware version ≥3.00.00.R can be identified by the imprint 1:On-Grid on the box label.
• Ensure that the inverter is equipped with a firmware version that are suitable for the respective system.
Change to the names and units of grid parameters to comply with the grid-connection
requirements in accordance with Regulation (EU) 2016/631 (valid from April 27, 2019)
To comply with the EU grid-connection requirements (valid from April 27, 2019) the names and units of grid
parameters were changed. The change is valid from firmware version ≥3.00.00.R. Names and units of grid
parameters for inverters with firmware version ≤2.99.99.R are not affected by this change and remain valid.
2.3 Battery Safety Information
This section contains safety information that must be observed at all times when working on or with batteries.
To prevent personal injury or property damage and to ensure long-term operation of the batteries, read this section
carefully and observe all safety information at all times.
