2.1 Intended Use
The SunnyTripower is a transformerless PV inverter, with 12 MPPtrackers, that converts the direct
current of the PV array to grid-compliant, three-phase current and feeds it into the utility grid.
The product is intended for use in industrial environments.
The product must only be accessible to qualified persons.
The product complies with EN55011 of class A, group 1:
• a.c. mains power port: ≤ 20 kVA
• d.c. power port: > 75 kVA
• Electromagnetic radiation disturbance: ≤ 20 kVA
In accordance with EN55011, the product must only be operated at locations where the distance
between the product and third-party radio-communication installations is greater than 30m. This
distance must be maintained from persons carrying radio or electromagnetically sensitive
equipment.
The product is not intended to be used in living areas and cannot provide protection of radio
reception against interference signals in such environments.
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 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.
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 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.
The enclosed documentation is an integral part of this product. Keep the documentation in a
convenient, dry place for future reference and observe all instructions contained therein.

2.2 IMPORTANT SAFETY INSTRUCTIONS
Keep the manual for future reference.
This section contains safety information that must be observed at all times when working.
The product has been designed and tested in accordance with international safety requirements. As
with all electrical or electronical devices, there are residual risks despite careful construction. To
prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.
DANGER
Danger to life due to electric shock when live components or cables are
touched
High voltages are present in the conductive components or cables of the product. Touching live
parts and cables results in death or lethal injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Disconnect the product from voltage sources and ensure it cannot be reconnected before
working on the device.
• Wear suitable personal protective equipment for all work on the product.
DANGER
Danger to life due to electric shock when live components or DC cables are
touched
When exposed to light, the PV modules generate high DC voltage which is present in the DC
cables. Touching live DC cables results in death or lethal injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Disconnect the product from voltage sources and ensure it cannot be reconnected before
working on the device.
• Do not disconnect the DC connectors under load.
• Wear suitable personal protective equipment for all work on the product.
