Description Troubleshooting
25 Isolation
Fault PV Isolation fault. The
inverter has detected
the PV solar generator
is not properly isolated
from ground earth. The
isolation is checked
every time before the
inverter starts
operation. If the problem persists:

Check the PV installation for
isolation problems and ground
leakage.

Only a certified PV installer must fix
the faulty string before connecting it
to the inverter.
26 Faulty AC
Relay The AC relay failed
during wake-up tests. If the problem persists:

Disconnect inverter from AC grid.

Contact SolarEdge support.
27 Hardware
Error Internal hardware
error. If the problem persists, contact
SolarEdge support.
28 RCD Sensor
Error The RCD measurement
mechanism has failed
during the wake-up test
phase. If the problem persists, contact
SolarEdge support.
29-30 Phase
Balance
Error The monitoring
hardware that checks
the balance of each
phase (L1-N and L2-
N) has exceeded its
limit. This error is
checked only in the
USA.

Check the grid connection.

Check the GND wire connection.

Check the L1, L2 and Neutral wire
connections.

Verify symmetric load between L1
and L2.

Consult the local grid authority.
31 AC Voltage
Too High Grid voltage is above
the limit permitted in
this country.

Turn off the inverters in the site and
verify AC grid voltage.

If the inverter is located far from the
connection point to the grid, then use
a wider gauge AC wire.

Consult the grid operator.

If you are permitted by the local
authorities, then use the SolarEdge
Configuration Tool to change the
range. Refer to the
SolarEdge
Installation Tool User Guide for
mode detail.
