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 suitable for indoor and outdoor use.
The product must only be operated with PV arrays (PV modules and cabling) that are approved by
the electrical standards applicable on-site and the National Electrical Code
the Canadian Electrical Code
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 user interface of the product.
• Only ground the mounting frames of the PV modules.
• The neutral conductor of the AC output is grounded within the product as standard.
When connecting a utility grid with neutral conductor, the bridge between the neutral
conductor of the AC output and the enclosure must be removed.
PV modules with a high capacity to ground may only be used if their coupling capacity does not
exceed 12.6 μF.
All components must remain within their permitted operating ranges and their installation
requirements at all times.
