Error Messages
An Error message is caused by a critical inverter fault. When this occurs, the inverter will usually shut
down and will display a fault LED. One or more messages in this menu will change from
N
to
Y
. An error is
also accompanied by an event message (see page
2461).
See the inverter Operator's Manual for more information on troubleshooting a specific error.
Figure 31 Inverter Errors
Screen Items:
Low Output Voltage:
The inverter’s AC regulation
cannot be maintained under high load conditions.
AC Output Shorted:
The inverter exceeded its
maximum surge current due to severe overload.
AC Output Backfeed:
Usually indicates another AC
power source (out of phase with the inverter) was
connected to the unit’s AC output.
Stacking Error:
A programming problem among
stacked units. (Often occurs if there is no master.)
Low Battery V:
he DC voltage is below the Low Battery
Cut-Out (LBCO) set point. (See page 85.)
High Battery V:
The DC voltage is above the inverter’s
acceptable level (as specified in the Operator’s Manual
for the appropriate inverter).
Over Temperature:
The inverter has exceeded its
maximum allowed operating temperature.
Phase Loss:
A slave was ordered to transfer to AC by
the master, but no AC is present. The unit continues
inverting. This is the only “Error” that is not
accompanied by a shutdown.
Soft Keys:
<Back> returns to the previous screen.
<Port> cycles through each device
connected to the network.
