6.2 Errors

Error message

Explanation / Action
Mains voltage too high The grid voltage of one or more phases present at the inverter exceeds the permissible value according
to the national standards of the country selected. The inverter must not feed into the grid. Contact your
installer.
Mains voltage too low The grid voltage of one or more phases present at the inverter is lower than the permissible value accord-
ing to the national standards of the country selected. The inverter must not feed into the grid. Contact
your installer.
Mains frequency too The mains frequency at the inverter exceeds the maximum permissible value for the selected country. The
high inverter must not feed into the grid. Contact your installer.
Mains frequency too The mains frequency at the inverter is less than the minimum permissible value for the selected country.
low The inverter must not feed into the grid. Contact your installer.
Residual current too The residual current flowing from the positive or negative inputs to earth via the photovoltaic modules
high exceeds the maximum permissible value. The inverter must not feed into the grid. Contact your installer.
Mains DC current too The DC current portion fed into the grid by the inverter exceeds the maximum permissible value for the
high selected country. The inverter must not feed into the grid. Contact your installer.
Isolation error The isolation resistance between the positive or negative input and earth is less than the permissible value.
The inverter must not switch onto the grid. Contact your installer.
Invalid country settings One or more inverters have an invalid country code. Either no country was selected during commissioning
or differing countries are selected for multiple inverters in the same system. The inverter(s) do(es) not feed
into the grid.
Set a valid country code in the inverter.
DC input voltage too The input voltage at the inverter exceeds the permissible value. The inverter does not feed into the grid.
high Switch off the DC switch and contact your installer.
DC input voltage too The input voltage at the inverter is less than the permissible value. The inverter cannot feed into the grid.
low Contact your installer.
Internal error Contact your installer.
Internal warning Contact your installer.
Internal information Contact your installer.
Derating temperature The inverter cannot feed the grid at full power because the maximum permissible internal temperature
has been reached.
Contact your installer if this warning occurs frequently.
Derating 10 minutes The inverter cannot or may not feed the grid at full power because the average output voltage over a
average value period of 10 minutes lies outside the permissible tolerance range. Contact your installer if this warning
occurs frequently.
Derating external (e.g. The inverter has received an external signal via the communications interface and is currently feeding the
power supply company) grid at reduced power.
Derating temperature > The inverter cannot feed the grid at full power because the maximum permissible internal temperature
30 min has been reached. This state has now existed for more than 30 minutes. Contact your installer.
Derating 10 minutes The inverter cannot or may not feed the grid at full power because the average output voltage over a
average value > 30 min period of 10 minutes has been outside the permissible tolerance range for over 30 minutes. Contact your
installer if this warning occurs frequently.
Derating external (e.g. The inverter has received an external signal via the communications interface and is currently feeding the
power supply company) grid at reduced power. This state has now existed for more than 30 minutes.
> 30 min
Date/time not set The time and/or date have not been correctly set at the inverter. The inverter operates without restrictions
but the measurements are not correctly stored in the internal data logger. Set the time and date at the
inverter (see the StecaGrid Vision manual).
Option card error The communications card inserted into the inverter has signalled an error. The communication to the
outside world is possibly interrupted but the inverter is otherwise operating without restrictions. Check
the communications and/or contact your installer.
24h no energy injection The inverter has fed no power into the grid for at least 24 hours.
Check if the DC switch is switched off or if snow is lying on the modules. If neither is the case then contact
your installer.
Grid error (grid island- The output voltage between two or more phases of the inverter lies outside the permissible tolerance
ing detected) range. The inverter switches off for safety reasons.
