5.2 PV Generator Requirements

The Sunny Boy is designed to be connected to up to three strings (PV modules wired in

series) having a homogenous structure (modules of the same type, identical orientation

and tilt).

Sunny Design will assist you in the system design and checking of the string size for a

given type of inverter. Further information on Sunny Design is available at

www.SMA.de.

The unit has six 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:

5.3 Low Voltage Grid (AC)

The Sunny Boy must have a three-conductor connection to the grid (live (L), neutral (N),

protective earth (PE)).

The grid connection terminals on the AC connection

socket included in the accessories kit 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 cross-

section between 9 mm² and 13.5 mm², while the

PG16 connection socket is used for cables with a

cross-section up to a maximum of 17 mm². For detailed instructions, see sections

"Connecting the AC Output with PG13.5" (Page 26) and "Connecting the AC Output

with PG16" (Page 28).

• Multi-Contact 3 mm: SWR-MC

• Multi-Contact 4 mm: MC-SET

• Tyco: TYCO-SET

Limit values for DC input

Max. voltage 600 V (DC)

Max. input current 12 A (DC)

Warning!

We recommend using a 16 A line circuit

breaker to protect the power circuit. No

loads should be connected to this power

circuit.
