Disconnect Messages

Disconnect screens explain the reason that the inverter rejected an AC source. The unit returns to
inverting mode if turned on. The ERROR LED (see page 11) will not illuminate for a Disconnect
message, although it may flash for a concurrent warning following the disconnect. (See previous
page.) If the AC source is removed, the warning and the LED will be blank, but the cause of the last
disconnect will remain. See the system display manual for instructions on viewing disconnect
messages. One or more messages in this menu will display yes. If a message says no, it is not the
cause of disconnection.
Disconnect screens only display the reason for the disconnection; they cannot correct it. It is usually
the result of external conditions, not an inverter fault. A few settings can be changed to
accommodate problems with the AC source.
Disconnect messages are not the same as the Stop Sell Reasons (see next page), although they may be
caused by the same circumstance. A grid-interactive unit can stop selling and still remain connected
to the utility grid.

Check AC source. If it is a generator,
reduce speed.
Check AC source. If it is a generator,
increase speed.
Check AC source. The inverter's

fix it.
