INTENDED USE
The Sunny Boy is a transformerless PV inverter 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 suitable for use with this product.
PV modules with a large capacity to ground must only be used if their coupling capacity does not exceed 900nF (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 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. modications or conversions, are only permitted with the express written permission of
SMASolarTechnologyAG. Unauthorized alterations will void guarantee and warranty claims and usually void the
operating license. SMASolarTechnologyAG shall not be held liable for any damage caused by such alterations.
Any use of the product other than that described in the Intended Use section does not qualify as appropriate.

SYMBOLS
Danger to life due to electric shock
The inverter operates at high voltages. Prior to performing any work on the inverter, disconnect
it from voltage sources. All work on the inverter must only be carried out by electrically qualied
persons.
Risk of burns due to hot surfaces
The inverter can get hot during operation. Avoid contact during operation. Allow the inverter to
cool down suciently before carrying out any work.
Notice
This symbol indicates general dangers. In this case, it indicates that the inverter must be
additionally grounded or that equipotential bonding is required locally.
Danger to life due to high voltages in the inverter: observe the prescribed waiting time
of ve minutes
High voltages that can cause lethal electric shocks are present in the live components of the
inverter. Always disconnect the inverter from voltage sources before performing any work on it.
Tapping
Tap twice on the enclosure lid to activate the WPS function of the inverter. WPS enables the
automatic connection to an end device via WLAN.
