4.2 Requirements: PV-Modules
The Sunny Boy 2800i is designed for the connection of up to three
strings (PV modules connected in series).
The „ GenAu“ tool will help to dimension and check the size of
your strings with respect to the Sunny Boy you intend to use. The
„ GenAu“ tool is available for download at www.SMA.de.
The device has six Multi-Contact plug connectors (two for each
string). The connecting cables of the PV panel therefore have to
be equipped with such plug connectors as well.
A connection kit for connection of loose cable ends in a string can
be purchased as an accessory (SMA order name: „ SWR-MC“).)
