Multifunction Relay
The inverter is equipped with a multifunction relay as standard. The multifunction relay is an
interface that can be configured for the operating mode used by a particular system.
Error message required by standard
In some countries, signaling of errors is required by standards, e.g. IEC 62109-2. In order to
meet the standard requirement, take one of the following measures:
• Operate the multifunction relay in the operating mode
Fault indication
or
FltInd
and
connect a display unit to the multifunction relay that signals an error or the undisturbed
operation of the inverter.
• Activate the error alarm in Sunny Portal (for information on receiving error alarms via
Sunny Portal, see the Sunny Portal user manual at www.SunnyPortal.com). This requires
the inverter to be registered in Sunny Portal.
SMA OptiTrac Global Peak
SMA OptiTrac Global Peak is an advancement of SMA OptiTrac and allows the operating point of
the inverter to follow the optimal operating point of the PV array (MPP) precisely at all times. In
addition, with the aid of SMA OptiTrac Global Peak, the inverter detects several maximum power
points in the available operating range, such as may occur particularly with partially shaded
strings. SMA OptiTrac Global Peak is enabled by default.
All-pole sensitive residual-current monitoring unit
The all-pole sensitive residual-current monitoring unit detects alternating and direct differential
currents. In single-phase and three-phase inverters, the integrated differential current sensor detects
the current difference between the neutral conductor and the line conductor(s). If the current
difference increases suddenly, the inverter disconnects from the utility grid.
