DC Voltage Too
High
The SolarEdge system normally eliminates DC overvoltage
errors. If the fault persists:
o
Turn OFF the inverter ON/OFF switch. If after five
minutes, the LCD panel does not show a low safety
voltage (1V per optimizer), check which string is
malfunctioning and recheck its connections to the
inverter.
o
Proceed according to Power Optimizer Troubleshooting
on page 88
o
Re-commission all inverters in the site, as described in
Commissioning the Installation on page 55

Temperature
Too High
o
Verify proper inverter clearances.
o
Make sure the heat-sink fins are clean and unobstructed.

Faulty Temp.
Sensor
Broken or unconnected temperature sensor. Contact
SolarEdge Support.
25 121 Isolation Fault
o
Check the PV installation for isolation problems and
ground leakage.
o
Only a certified PV installer must fix the faulty string
before connecting it to the inverter.

Error
o
Check the grid connection.
o
Check the GND connection.
o
Check the L1, L2 and Neutral connections.
o
Verify symmetric load between L1 and L2.
o
Consult the local grid authority.

AC Voltage Too
High (Line
1/2/3)
o
Verify that the inverter is set to the correct country.
o
Turn OFF the inverters in the site and verify AC grid
voltage.
o
If the inverter is located far from the connection point to
the grid, use a larger gauge AC wire.
o
Consult the grid operator.
