2.1
Intended Use
The Sunny Boy is a transformerless PV inverter with two MPP trackers which converts the direct
current of the PV array to grid-compliant alternating current and feeds it into the utility grid.
The product is suitable for indoor and outdoor use.
The product must only be operated with PV arrays of protection class II in accordance with
IEC 61730, application class A. The PV modules must be compatible with this product.
The product is not equipped with a 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.
PV modules with a high capacity to ground must only be used if their coupling capacity does not
exceed 1.4 μF (for information on how to calculate the coupling capacity, see the Technical
Information "Leading Leakage Currents" at www.SMA-Solar.com).
All components must remain within their permitted operating ranges and their installation
requirements at all times.
The product must only be used in countries for which it is approved or released by SMA Solar
Technology AG and the grid operator.
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 Solar Technology AG. Unauthorized alterations 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 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.
