Appendix A: Errors and Troubleshooting
This appendix describes the error messages that appear on the inverter LCD panel when an error occurs,
and how to troubleshoot them.
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.
Tous les avertissements et précautions mentionnés dans ce manuel doivent être aussi appliqués en
cas de dépannage.

9, 13
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.

Ground Current -
RCD
Ground current surge.
The internal hardware
that measures ground
fault has measured
substantially high
ground currents.
Ground faults may occur due to insufficient insulation to
the ground.
DO NOT TOUCH UN-INSULATED WIRES!
EXTREME CARE MUST BE TAKEN WHEN
TROUBLESHOOTING THIS ERROR.
THE RISK OF ELECTROCUTION EXISTS!
Only a qualified technician should handle this
problem, and only after taking proper precautions.
Turn the inverter ON/OFF switch to OFF.
Wait five minutes for the input capacitors to
discharge.
Disconnect the AC breaker.
Disconnect the DC inputs.
For each DC string, measure the DC voltage
between DC- and GND and DC+ and GND with a
1Kohm resistor in parallel to the voltmeter. If a
voltage higher than 2 V is measured, then the fault
is in this string.
Do not connect strings with a grounding fault to the
inverter.
For further documentation about possible ground
current error sources and solutions contact
SolarEdge support.
