10 Error messages and trouble shooting
10.1 Errors
Number Message Possible cause Solution
E01 AC Freq High
Current grid frequency is above the OFR setting
(over frequency recognition).
Check the grid frequency on the inverter display.
Incorrect country setting. Check country setting on the inverter display.
E02 AC Freq Low
Current grid frequency is below the UFR setting
(under frequency recognition).
Check the grid frequency on the inverter display.
Incorrect country or grid setting. Check country and grid setting.
E11, E13,
E16, E18,
E21, E23
AC Volt High
Current grid voltage is above the OVR setting
(over voltage recognition).
Check the grid voltage on the inverter display.
Grid voltage is over the Slow OVR setting dur-
ing operation.
Check the grid voltage on the inverter display.
Incorrect country or grid setting. Check country and grid settings.
E10, E15,
E20
AC Volt Low
Current grid voltage is under the UVR setting
(under voltage recognition).
Check the grid voltage connection to inverter
terminal.
Incorrect country or grid setting. Check country and grid setting.
Wrong wiring in AC plug. Check wiring of AC plug.
E07 Grid Quality Non-linear load in grid and near to inverter.
Grid connection of inverter needs to be far away
from non-linear load if necessary.
E08 HW Connect Fail Wrong wiring in AC plug. Check wiring of AC plug.
E34 Insulation
PV array insulation fault. Check the insulation of DC inputs.
Large PV array capacitance between Plus and
Ground, or Minus and Ground, or both.
Check the capacitance, dry PV panels if neces-
sary.
E09 No Grid
AC/DC disconnection switch is in position OFF.
Turn the AC/DC disconnection switch to position
ON.
AC plug is not properly connected.
Check the connection in AC plug and make sure
it connects to inverter.
Wrong wiring in AC plug Check wiring of AC plug.
E30 Solar1 High
DC input voltage at DC1 is above the maximum
allowed DC input voltage.
Modify the solar array setting, so that the DC
input voltage at DC1 is below the maximum
allowed DC input voltage.
E31 Solar2 High
DC input voltage at DC2 is above the maximum
allowed DC input voltage.
Modify the solar array setting, so that the DC
input voltage at DC1 is below the maximum
allowed DC input voltage.
