2.1 Intended Use
The Sunny Tripower is a transformerless PV inverter,
with 6 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 complies with EN 55011:2016 +
A1:2017 of group 1, class A:
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.
PV modules with a high capacity to ground must
only be used if their coupling capacity does not
exceed 12.6 μF (for information on how to
determine 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.
