Please check in the display for the cause of the lack of production. There will be a short text
describing the event. The table below provides information regarding event texts. The red LED
will start flashing in case of a failure.

Remember that only trained and authorised personnel familiar with electrical sys-
tems and safety issues may work on inverters and electrical installations.
Check that the grid is properly connected to the inverter and that the mains switch is not
switched off.
Check that there is sufficient solar radiation to generate power. U
Check for shading and loose cables/connections in the PV system.
Check whether the voltage of the PV modules are within the expected values. If not go
to point 7.
Check whether the voltage values of the grid lie within the threshold values. If this is not
the case please contact your public utility for technical assistance.
If the above-mentioned points are OK, wait 15 minutes to find out whether there is a
permanent failure.
If the PV system still does not supply any power to the grid, please check the voltage,
current and power of the PV module as well as voltage, current and power of the grid in
the display. Additionally look in the log area of the display for event text and then call
service.
Description
Grid values are out of range
The PV isolation resistance is too low Make a visual inspection of all PV cables and modules. If the event
An internal event has occurred
Internal or AC installation error
Remedy
Check the voltage and frequency values in the display. If values are
zero, check the circuit-breaker (fuses) and cables. If values are out-
side the applied limits, request technical service from installer/en-
ergy company.
occurs frequently, request technical service.
Make sure airflow over the heat sink is not obstructed. Wait 5 mi-
nutes. If the inverter does not reconnect (although sufficient irradi-
ance is available) or the event occurs regularly, action must be tak-
en. Service inverter.
Turn off both AC and DC (PV) power to the inverter. Make a visual
inspection of the PV installation, if everything is in order, wait 5 mi-
nutes and re-apply AC and DC (PV) power. If the inverter resumes
fail safe operation, action must be taken. Service inverter.
