4.2 PV generator requirements
The Sunny Boy 1700 is designed to be connected to up to two strings (PV modules
wired in series) having a homogenous structure (modules of the same type, identical
orientation and angle).
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 unit has four DC plug connectors (two for each string) for connecting the PV
generators. The connecting cables from the PV generators must also be fitted with this
type of plug connector. A pre-assembled set for connecting the free cable ends from
a string is available as an optional accessory. The SMA order codes for the various
connectors are as follows:
• Multi-contact 3 mm: "SWR-MC"
• Multi-contact 4 mm: "MC-SET"
• Tyco:
"TYCO-SET"
4.3 Low Voltage Grid 230 V (AC) Requirements
The Sunny Boy must have a three-conductor connection to the mains (live (L), neutral
(N), protective earth (PE)).
The grid connection terminals on the AC connection
socket included in the delivery of your Sunny Boy can
take wires with a cross-section of up to 2.5 mm². The
accessories kit also contains a PG13.5 AC connection
socket for connecting cables with a diameter between
9 mm and 13.5 mm, while the PG16 connection socket
is used for cables with a diameter up to a maximum of 17 mm. For detailed
instructions, see sections "Connecting the AC output with PG13.5" (page 22) and
"Connecting the AC plug with PG16" (page 24).
