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 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 arrays (PV modules and cabling) that are approved by the electrical standards applicable on-site and the National Electrical Code® ANSI/NFPA 70 or the Canadian Electrical Code® CSA C22.1.
Transformerless (Non-isolated)
The product is not equipped with a transformer and therefore has no galvanic isolation.
The neutral conductor of the AC output is not bonded to ground within the product.
- 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 not bonded to ground within the product. When connecting a utility grid without neutral conductor, N and PE of the AC terminal must be bridged.
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.
All components must remain within their permitted operating ranges and their installation requirements at all times.
The product is approved for the US and Canadian market.
