Voltage at AC connection
Line conductor L1
: The master
has measured an undesired volt-
age at connection
AC1
.
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).
