Intended Use

The Sunny Highpower is a transformerless PV inverter. It converts the direct current from the PV modules into grid-compliant three-phase current and feeds it into the utility grid via a separate transformer.

The product is intended for use in commercial, industrial or business sectors.

The product is suitable for operation in a chemically active environment in accordance with IEC 60721-3-4 as per Class 4C2.

The product is suitable for indoor and outdoor use.

When used indoors, the ventilation system at the installation site must be able to dissipate the power loss that occurs.

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 may only be operated in connection with a suitable medium-voltage transformer. The low-voltage side must be configured in a star formation and the neutral point must be 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).

PV modules with a high capacity to ground must only be used if the coupling capacity of all PV modules does not exceed 32 μF.

All components must remain within their permitted operating ranges and their installation requirements at all times.
