Product Overview

Product Description
The Sunny Tripower is a transformerless PV inverter, with 2 MPP trackers, that converts the direct
current of the PV array to grid-compliant, three-phase current and feeds it into the utility grid.
No galvanic isolation
The product is not equipped with a transformer and therefore has no galvanic isolation.
• Do not operate grounded PV modules together with the product. If grounded PV modules
are connected to the product, an event will occur. The event will be displayed, along with
the associated message, in the event list on the communication product.
• Only ground the mounting frames of the PV modules.
• The neutral conductor of the AC output is not bonded to ground within the product.
