Sma Optitrac Global Peak - SMA SUNNY TRIPOWER 12000TL-US Instructions D'installation

4 Product Overview SMA Solar Technology America LLC
RS485 Interface
The inverter can communicate via cables with special SMA communication products via the RS485
interface (information on supported SMA products at www.SMA-Solar.com). The RS485 interface
can be retrofitted and can be used in place of the SMA Speedwire/Webconnect interface in the
inverter.
Class 1 wiring methods are to be used for field wiring connection to the terminals of the
communication interface.
Grid Management Services
The inverter is a grid support interactive inverter.
The inverter was tested in accordance with the UL 1741 SA (2016-09-07) to be compliant with the
source requirements documents of the states available at the time. For connecting the inverter to the
utility grid, no additional grid monitoring equipment is necessary. A description of the tested
functions and instructions on the activation and setting of functions can be found in the technical
information "Grid Support Utility Interactive Inverters" at www.SMA-Solar.com.
PV Rapid Shutdown System Equipment
The inverter is a PV Rapid Shutdown System Equipment and performs the function of voltage
reduction according to UL 1741 CRD PV Rapid Shutdown Systems 2015. When a rapid shutdown
is triggered by disconnecting the utility grid, the inverter discharges independently on the AC side to
≤ 30 V within 30 seconds.
If a disconnection device is used in addition between the inverter and the PV array that disconnects
the PV array in the case of a rapid shutdown, the inverter discharges independently on the DC side
to ≤ 30 V within 30 seconds.
The electric discharge on the DC side is deactivated by default and must be activated manually
after commissioning of the inverter(see Section 8.7 "Activating of the Rapid Shutdown DC
discharge function", page 42).
NOTICE - The Rapid Shutdown is tripped when opening the AC Disconnect. The AC Disconnect
must be clearly identified as Rapid Shutdown Initiator in accordance with National Electrical
®
Code . The status of the Rapid Shutdown System is indicated depending on the On/Off position of
the AC Disconnect.
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. You can activate SMA OptiTrac Global Peak via the operating parameters (see Section 8.5
"Setting SMA OptiTrac Global Peak", page 40).
Arc-Fault Circuit Interrupter (AFCI)
®
In accordance with the National Electrical Code
, the inverter has a system for arc fault detection
and interruption.
