4.3 AC Voltage Configuration

The Sunny Boy 8000-US must not be connected to a 208 V grid.
The Sunny Boy is compatible with the following grid types:
• 208 V AC (not Sunny Boy 8000-US)
• 240 V AC
• 277 V AC
The Sunny Boy is configured ex works for connection to
the power distribution grid with a voltage of 240 V AC.
The Sunny Boy can be configured for other voltages.
4 cables are inserted into the enclosure via a cable
support sleeve. Each cable is labeled with its respective
voltage.
1. Connect the cable with the correct voltage to the
left terminal block (A).
2. To adjust the AC voltage, select the cable with the
correct voltage at the right terminal block (C).
Connect the selected cable to the left side of the left
terminal block (A).
3. Secure all screw terminals. If spring-type terminals
are available, close the levers of the terminals by
pressing down.
