2.1 Intended Use
The SunnyHighpower is a transformerless PVinverter. It converts the direct current from the PV
modules into grid-compliant three-phase current and feeds it into the utility grid via a separate
transformer.
With the SunnyHighpower100 it is possible to feed the three-phase current directly into the low-
voltage grid while complying with the locally applicable connection requirements.
The product is intended for use in industrial environments.
In accordance with EN55011, the product must only be operated at locations where the distance
between the product and third-party radio-communication installations is greater than 30m.
The product is suitable for operation in a chemically active environment in accordance with
IEC60721-3-4 as per Class4C2.
The product is suitable for indoor and outdoor use.
When used indoors, the ventilation system at the installation site must be able to dissipate the
power loss that occurs.
The product must only be operated with PV modules of protection class II in accordance with
IEC61730, application class A. The PV modules must be compatible with this product.
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).
The product is not equipped with an integrated transformer and therefore has no galvanic isolation.
The product must not be operated with PV modules whose outputs are grounded. This can cause
the product to be destroyed. The product may be operated with PV modules whose frame is
grounded.
All components must remain within their permitted operating ranges and their installation
requirements at all times.
Use SMA products only in accordance with the information provided in the enclosed
documentation and with the locally applicable laws, regulations, standards and directives. Any
other application may cause personal injury or property damage.
Alterations to SMA products, e.g., changes or modifications, are only permitted with the express
written permission of and according to the instructions from SMA Solar Technology AG.
Unauthorized alterations can be dangerous and lead to personal injury. In addition, an
unauthorized alteration will void guarantee and warranty claims and in most cases terminate the
operating license. SMA Solar Technology AG 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
appropriate.
