AC Voltage Too
High (Line
1/2/3)
AC voltage surge. The internal hardware that
measures AC voltage has measured substantially high
sudden output voltage
If the fault persists:
o
Check the AC connection to inverter.
o
Verify that the inverter is set to the correct country.
o
Check with the grid operator if a large surge source or
irregular load exists near the site.
o
Verify that the output wire size matches the distance
between the inverter and the location of the grid
connection.
o
Use a larger gauge wire for the AC output.
o
Refer to the AC Wiring Application Note, available on
the SolarEdge website at
http://www.solaredge.us/files/pdfs/application-note-
recommended-wiring.pdf
15 102
DC Voltage Too
High
DC overvoltage. The input DC voltage exceeds the
maximum supported level.
The SolarEdge system normally eliminates DC overvoltage
errors: When DC overvoltage is detected, the inverter shuts
off the power optimizers and restarts. 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 94
o
Re-commission all inverters in the site, as described in
Commissioning the Installation on page 43
