3 Product Overview
SMA Solar Technology AG
Grid Management Services
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 Equipment
The inverter is listed as PV Rapid Shutdown Equipment (PVRSE) according to UL 1741.
All DC inputs and AC outputs of this product comply with photovoltaic rapid shutdown requirements
for controlled conductors outside the array.
A complete PV Rapid Shutdown System consists of the inverter, PV array switching devices, and a
Rapid Shutdown initiation device.
NOTICE - The inverter's Rapid Shutdown function is initiated by disconnecting the inverter from the
AC grid voltage, for example, by opening the main PV system AC disconnect. The AC disconnect
that serves as the Rapid Shutdown initiation device must be readily accessible and clearly marked
®
in accordance with National Electrical Code
. The Rapid Shutdown status of the PV system will be
indicated by the On/Off (Closed/Open) position of this AC disconnect. The Off (Open) position
indicates that Rapid Shutdown has been initiated.
When switching devices compliant with the SunSpec Communication Signal for Rapid Shutdown
are installed within the PV array, the inverter can transmit a SunSpec-compliant "permission to
operate" signal to the PV array switching devices via its DC input conductors. When Rapid
Shutdown is initiated, the inverter will stop transmitting the SunSpec signal. When the SunSpec
signal is not being received, the PV array switching devices are responsible for limiting voltages on
®
conductors inside the PV array in accordance with National Electrical Code
. It is important that
during a Rapid Shutdown via the SunSpec communication signal all PV modules of a string are
always equipped with SunSpec-compliant PV array switching devices, otherwise the inverter cannot
start feed-in operation. To ensure safe discharging of the DC connection lines, the standby voltage
of the used PV array switching devices of a string must be < 30 V.
A PV Rapid Shutdown System can also be installed using PV array switching devices initiated by
loss of grid AC voltage or other means. In these cases, it must be ensured that the PV system Rapid
Shutdown initiation device initiates Rapid Shutdown of the PV array devices at the same time that
the inverter is disconnected from AC voltage. The PV array switching devices must disconnect the
PV array from the inverter within a maximum of 15 seconds after Rapid Shutdown initiation.
The inverter is capable of grid support operation where in case of a loss of AC voltage, the inverter
remains connected to the utility grid for a defined ride-through time and waits for voltage recovery.
If grid voltage does not recover within the defined ride-through time, the inverter disconnects from
the grid and Rapid Shutdown is initiated.
