10 Troubleshooting
Corrective measures
A bypass switch may have bridged the
internal transfer relay.
• Ensure that the bypass switch is in
the position for operation with the
Sunny Island.
• Ensure that the bypass switch is in
the position for operation with the
Sunny Island.
An external energy source (e.g., genera-
tor) may have been connected to the
connection AC1.
• Disconnect external energy source
from connection AC1 and connect
to connection AC2 (see the
Sunny Island inverter installation
manual).
• Reduce the power of the loads.
• Reduce the power of the loads.
