Error Codes
The error code numbers may differ depending on the inverter type (single phase or three phase) as
described in the table below.
The error messages include an error number and a description, and have the following format:
E r r o r c o d e X X X
X X X X X X X X X X X X X X X X X X X X
X X X X X X X X X X X X X X X X X X X X
An error message is displayed for 30 seconds, after which the inverter waits the necessary reconnection
time and then restarts. During this time, the LCD displays the Waking Up message and the remaining time
to reconnection.
WARNING!
All Warnings and Cautions in this manual should be adhered to while troubleshooting an error.

If the fault persists, contact SolarEdge
support.
N/A

Wrong AC
connection
The lines connections
to the inverter are
incorrect, for example:
AC line 1 from the grid
is connected to line 2 at
the inverter so there is
no 120deg between L2
to L1 and L3 to L2 at
the inverter side.
Switch between L1 and L2 or L2 and L3
connections

N/A
AC Current Surge
The internal hardware
that measures AC
current has measured
substantially high
output currents. This
may occur because of
changes in the AC
voltage or a switching
load near the site.
If the fault persists:
 Check the AC connection to the
inverter.
 Check with the grid operator if a large
surge source or irregular load exists
near the site.
 If the grid does not have problems
contact SolarEdge support.
