Intended Use

The Sunny Highpower is a transformerless PV inverter. It converts the direct current from the
PV array into grid-compliant three-phase current and feeds it into the utility grid via a separate
transformer.
The product is intended for use in commercial, industrial or business sectors.
The product is suitable for operation in a chemically active environment in accordance with
IEC 60721-3-4 as per Class 4C2.
The product is suitable for indoor and outdoor use.
The product must only be operated with PV modules of protection class II in accordance with
IEC 61730, application class A. The PV modules must be compatible with this product.
The product must only be operated with PV arrays (PV modules and cabling) that are approved by
the electrical standards applicable on-site and the National Electrical Code
the Canadian Electrical Code
The product may only be operated in connection with a suitable medium-voltage transformer. The
low-voltage side must be configured in a star formation and the neutral point must be grounded (for
information about the requirements of the medium-voltage transformer, consult the technical
information "Important Requirements for Medium-Voltage Transformers" under www.SMA-
Solar.com).
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.
PV modules with a high capacity to ground may only be used if their coupling capacity does not
exceed 32 μF.
