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.
All components must remain within their permitted operating ranges at all times.
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
protection for ungrounded PV modules.
The product is approved for the USA market.
Use this product only in accordance with the information provided in the enclosed documentation
and with the locally applicable standards and directives. Any other application may cause
personal injury or property damage.
Alterations to the product, e.g. changes or modifications, are only permitted with the express written
permission of SMA. Unauthorized alterations will void guarantee and warranty claims and in most
cases terminate the operating license. SMA shall not be held liable for any damage caused by
such changes.
Any use of the product other than that described in the Intended Use section does not qualify as the
intended use.
The enclosed documentation is an integral part of this product. Keep the documentation in a
convenient place for future reference and observe all instructions contained therein.
The type label must remain permanently attached to the product.
