INTENDED USE
The Sunny Tripower is a transformerless PV inverter with two MPP trackers which 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. The product may 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.
PV modules with a large capacity to ground must only be used if their coupling capacity does not exceed 3.5 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 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. modifications 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.
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

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 may only be carried out by electrically qualified
persons.
Risk of burns due to hot surfaces
The inverter can become hot during operation. Avoid contact during operation. Allow the inverter
to cool down sufficiently before carrying out any work.
20 min
Danger to life due to high voltages in the inverter: observe the waiting time of 20 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.
