2.1 Intended Use
The SunnyTripower is a transformerless PV inverter, with 6 MPPtrackers, that converts the direct
current of the PV array to grid-compliant, three-phase current and feeds it into the utility grid.
The product is suitable for indoor and outdoor use.
The product may only be operated with PV arrays (PV modules and cabling) that are approved in
accordance with the electrical standards applicable on-site and the NationalElectricalCode®
ANSI/NFPA 70.
No galvanic isolation
The product is not equipped with a transformer and therefore has no galvanic isolation.
• Do not operate grounded PV modules together with the product. If grounded PV modules
are connected to the product, an event will occur. The event will be displayed, along with
the associated message, in the event list on the user interface of the product.
• Only ground the mounting frames of the PV modules.
• The neutral conductor of the AC output is grounded within the product as standard.
When connecting a utility grid with neutral conductor, the bridge between the neutral
conductor of the AC output and the enclosure must be removed.
PV modules with a high capacity to ground may only be used if their coupling capacity does not
exceed 12.6μF.
To protect the PV system against excessive reverse currents under fault conditions, a DC-side
overcurrent protective device must be connected in accordance with the National Electrical Code®
to prevent any short-circuit currents that exceed the ampacity of the DC electric circuit or the
maximum series fuse rating of the PV modules. Typically, this requires string fusing where more than
two strings are combined in parallel. Where an overcurrent protection device is required, the
National Electrical Code® requires that both positive and negative conductors have overcurrent
protection for ungrounded PV modules.
All components must remain within their permitted operating ranges and their installation
requirements at all times.

User ManualSTP33-62-US-41-BA-en_es-1016
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.
ENGLISH

3 Product Overview
SMA Solar Technology AG
User Manual STP33-62-US-41-BA-en_es-10 17
The Rapid Shutdown function is deactivated by default. The Rapid Shutdown function should only
be activated when PVRSE switching devices have been installed within the PV array or between the
PV array and the inverter. The Rapid Shutdown function can be activated during or after inverter
commissioning via the user interface by selecting the operating mode suitable to the PV array
PVRSE switching devices. If the Rapid Shutdown function is activated and PV array PVRSE switching
devices are not installed, the inverter cannot discharge the connected DC input conductors during
Rapid Shutdown and the inverter can be damaged.
WARNING - THIS PV RAPID SHUTDOWN EQUIPMENT DOES NOT PERFORM ALL OF THE
FUNCTIONS OF A COMPLETE PV RAPID SHUTDOWN SYSTEM. THIS PV RAPID SHUTDOWN
EQUIPMENT MUST BE INSTALLED WITH OTHER EQUIPMENT TO FORM A COMPLETE PV
RAPID SHUTDOWN SYSTEM THAT MEETS THE REQUIREMENTS OF NEC (NFPA 70) FOR
CONTROLLED CONDUCTORS OUTSIDE THE ARRAY. OTHER EQUIPMENT INSTALLED IN OR
ON THIS PV SYSTEM MAY ADVERSLY AFFECT THE OPERATION OF THE PV RAPID SHUTDOWN
SYSTEM. IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE THAT THE COMPLETED PV
SYSTEM MEETS THE RAPID SHUT DOWN FUNCTIONAL REQUIREMENTS. THIS EQUIPMENT
MUST BE INSTALLED ACCORDING TO THE MANUFACTURER’S INSTALLATION MANUAL.
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.
String-Failure Detection
The string-failure detection measures the total current of every input and continuously calculates the
mean values for the inputs in question. The total currents are compared with the mean values. If a
total current exceeds or falls short of the mean value by the set tolerance value, an event is
reported. Marginally increased total currents are reliably detected over several query intervals and
distinguished from typical current fluctuations of the PV array. String-failure detection is deactivated
by default and must be activated. In addition, the tolerance value can be set via the user interface
and the mean values read off.
Surge arrester type 2 and type 1+2
On the AC and DC side, the inverter is equipped with slots for type 2 or type 1+2 surge protection
devices. The surge protection devices limit dangerous overvoltages. The surge protection devices
can be retrofitted.
Arc-Fault Circuit Interrupter (AFCI)
In accordance with the National Electrical Code®, the inverter has a system for DC arc fault
detection and interruption. The arc-fault circuit interrupter is listed in accordance with UL 1699B Ed.
1. A detected electric arc causes the inverter to interrupt feed-in operation: In order to restart feed-in
operation, the feed-in operation must be activated manually. If the installation conditions allow it,
you can deactivate the arc-fault circuit interrupter.
SMA Smart Connected
SMA Smart Connected is the free monitoring of the inverter via the SMA SunnyPortal. Thanks to
SMA Smart Connected, the PV system operator and qualified person will be informed automatically
and proactively about inverter events that occur.

Importing and exporting files with end devices having an iOS operating
system is not possible.
For technical reasons, importing and exporting files (e.g. importing an inverter configuration,
saving the current inverter configuration or exporting events) is not possible with mobile end
devices having an iOS operating system.
• Use an end device that does not have an iOS operating system for importing and
exporting files.
The procedure can be different depending on the end devices. If the procedure described does not
apply to your end device, establish the direct connection via WLAN as described in the manual of
your end device.
Procedure:
1. If your end device has a WPS function:
• Activate the WPS function on the inverter. To do this, tap twice in succession on the
enclosure lid of the DC-Connection Unit next to the LEDs.
☑ The blue LED flashes quickly for approx. two minutes. The WPS function is active
during this time.
• Activate the WPS on your end device.
☑ The connection with your end device will be established automatically. It can take
up to 20seconds for this connection to be established.
2. If your end device has not a WPS function:
• Search for WLAN networks with your end device.
• Select the SSID of the inverter SMA[serial number] in the list with the found WLAN
networks.
• Enter the inverter WLAN password. Within the first tenfeed-in hours and prior to
completing the configuration by means of the installation assistant, you must use the
standard WLAN password SMA12345. After the first tenfeed-in hours or after
completing the configuration by means of the installation assistant, you must use the
device-specific WLAN password (WPA2-PSK) of the inverter. You find the WLAN
password (WPA2-PSK) on the type label.
