Switch

Switch on the PV load-break switch at the inverter and,
if available, at the PV array junction box.

3.2.3 Commissioning

The inverter starts automatically if sufficient solar irradiation
is available. Commissioning takes a few minutes. During this
period, the inverter performs a self-test.
INFORMATION
The inverter is protected against short-term reverse
polarity. The inverter does not generate feed-in
power until any reverse polarity is corrected.
Prolonged reverse polarity leads to a failure of the inverter
and thus will void the warranty.
• Make sure that the cables are correctly connected to
the inverter.

3.2.4 Grid Code File

INFORMATION
If the desired grid code is not available, or if the LCS
tool displays a warning about incompatible software
versions, the grid code and software library must be
updated on the LCS tool.
It is possible to create customer-specific grid code
files with adjusted set values. For this purpose, please
contact SMA Technology AG.
Installation Guide

3.2.5 Configuring the Fallback

If the communication between the inverter and the
SMA Inverter Manager is interrupted, the inverter switches
to a previously defined operating state (Fallback). The
desired operating state when communication is interrupted,
can be activated and configured with the customer-specific
grid code file or via the LCS tool. For further information on
the configuration of the system fallback between the
SMA Inverter Manager and a superior control unit
(e.g. SCADA system or Power Plant Controller) see
installation manual of the SMA Inverter Manager /
SMA Digital I/O Box / LCS Tool.
INFORMATION
Observe the specifications of your electric utility
company.
