Troubleshooting
15
DC Voltage Too High
DC overvoltage.
The DC voltage
exceeds the
maximum
supported level.
The SolarEdge system normally
eliminates DC overvoltage errors:
When DC overvoltage is detected,
the SMI shuts off the power
optimizers and restarts. If the fault
persists:
Turn OFF the SMI ON/OFF
switch. If after five minutes, the
LCD panel does not show a low
safety voltage (1V per power
optimizer), check which string is
malfunctioning and recheck its
connection to the combiner box.
Verify that no PV modules are
connected directly in the string
without a power optimizer.
Re-commission all SMIs in the
site, as described in
Commissioning the Installation
17
Temperature Too
High
Over
temperature.
If the fault persists:
Verify that proper clearance
exists around the SMI.
Check whether the SMI is
installed in an area with
temperatures outside its
operating range.
Re-install in a cooler location.
24
Faulty Temp. Sensor
Broken or
unconnected
temperature
sensor.
If the fault persists, contact
SolarEdge Support.
27
Hardware Error
Internal hardware
error.
If the fault persists, contact
SolarEdge Support.
