4.2 DC input prerequisites
Your Sunny Boy 3800 is equipped with Multi-Contact (4 mm) DC plug connectors as
standard. Depending on your order preferences, the Sunny Boy 3800 can be
equipped with other connector systems instead, such as Multi-Contact (3 mm) or Tyco
connectors.
The device has eight DC plug connectors for connecting an upstream rectifier /
overvoltage protection unit for the wind turbine. The connecting cables must also be
fitted with the same type of plug connector. A pre-plugged set for connecting loose
cables to the appropriate DC connector system of the Sunny Boy 3800 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 4mm: "MC-SET"
• Tyco:
"TYCO-SET"
4.3 Low voltage grid 230 V (AC)
The relevant technical regulations and the special instructions of the local grid
operator must be followed.
The connection terminals of the Windy Boy 5000 /
6000 are suitable for wire cross-sections of up to
16 mm². The external diameter of the cable must be
between 11 mm and 25 mm. If you use a cable with
a cross-section smaller than 14 mm (11 mm minimum),
the rubber bushing in the screw fitting must be
replaced by the one included with the inverter
The connection is made with three wires (L, N, PE).
Limit values for DC input
Max. voltage 600 V (DC)
Max. input current 30 A (DC)
Please make sure that the input voltage never exceeds 600 V.
Higher input voltages will damage the Sunny Boy 3800 and lead
to loss of any and all warranty rights!
Each connection to a Windy Boy 5000 /
6000 must be equipped with a separate
circuit breaker 40 A. No other consumers
may be connected to the cable.
