Intended Use

The Sunny Tripower is a transformerless PV inverter with 3 MPP trackers that converts the direct
current of the PV modules to grid-compliant three-phase current and feeds it into the utility grid.
The product is intended for use in residential and industrial environments.
The product complies with EN 62920 of class B, group 1.
The product is suitable for indoor and outdoor use.
If the product is operated with a medium-voltage transformer, the low-voltage side must be
configured in a star formation and the neutral point 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 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.
PV modules with a high capacity to ground must only be used if the coupling capacity of all PV
modules does not exceed 6 μF.
The product contains a product approved by Anatel under the number 09133-22-01318.
This product does not guarantee protection against harmful interference and must not cause harmful
disturbances to a properly authorized system. You can find more information on the Anatel website:
