Errors and Troubleshooting
Description
If this fault persists:

Check the AC connection
to inverter.

Ask the grid operator
whether a large surge
source or irregular load
exists near the site.

Verify that the gauge of the
AC output wire size is large
enough, and if not, use a
larger gauge wire.
The SolarEdge system should
normally eliminate DC
overvoltage errors. When DC
overvoltage is detected, the
inverter shuts off the power
optimizers and restarts the
inverter.
If this fault persists:

Turn the inverter OFF.
After at least five minutes,
the LCD panel should show
a safety voltage of 1 V
*string length. If it does
not, check which string is
malfunctioning and check
its connections to the
inverter.

Verify that no PV modules
are connected directly to
the inverter without a
power optimizer.

Recommission all inverters
in the site, as described in
Chapter 4, Commissioning
the Installation on page 33.
If this fault persists, contact
SolarEdge support.
