SMA SB 3300TL Installation - Manual (Page 15)

SMA Technologie AG Requirements for the Installation
Installation Guide SB3300TL-11:SE2006 Page 15
4.2 Requirements: PV Modules
The Sunny Boy 3300TL is designed for the connection of one string (PV modules con-
nected in series) with homogeneous structure (PV modules of the same type and same
direction).
The „Sunny Design“ tool will help to dimension and check the size of your string with
respect to the inverter you intend to use. Information about the „Sunny Design“ tool
is available at www.SMA.de.
The device has two PV plug connectors (for one DC input). The connecting cables of
the PV panel therefore have to be equipped with such plug connectors as well.
A connection kit for the connection of loose cable ends in a string can be purchased
as an accessory. In the following you find the SMA order numbers for the different
PV plug connectors:
• Multi-Contact 3 mm: „SWR-MC“
• Multi-Contact 4 mm: „MC-SET“
• Tyco:
„TYCO-SET“
4.3 Requirements: Grid 230 V (AC)
The relevant technical regulations as well as specific re-
quirements defined by the local public utility have to be
complied with.
The terminals of the Sunny Boy 3300TL are suitable for
cables with a cross-section of up to 10 mm². Their outer diameter should be between
9 mm and 17 mm. The Sunny Boy 3300TL is connected with three wires (L, N, PE).
Limits for DC input
max. voltage per string 750 V (DC)
max. input current per string 8 A (DC)
