5. 2 PV Generator Requirements
The Sunny Boys have two input areas "String A" and "String B", each equipped with a
separate MPP-tracker. The input area "String A" can be used for the connection of up
to two strings (modules connected in series) with identical properties (modules with iden-
tical orientation, identical type, slant and number). The input area "String B" can be
used for a single string, while this string can be different from the strings connected to
"String A".
“Sunny Design“ helps you design the system and check string size taking the relevant
inverter into consideration. Further information on "Sunny Design" is available at
www.SMA.de .
The unit has six DC plug connectors (four for String A and two for String B) for connect-
ing the PV generators. The connecting cables from the PV generators must also be fitted
with this type of plug connector. 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"
