"Fault" messages on the display/LED

Many fault signals indicate a fault in the grid. They are not operational faults of the inverter. The triggering levels are
defined in standards, e.g. VDE0126-1-1. The inverter shuts down if the values exceed or fall below the approved levels.

FS (fault status)
OS (operating status)
Details regarding the fault or operating status can be found either on the display or in the data that was recorded
through the RS485 interface.

Cause of fault Explanation/remedy
• Generator volt- • The PV generator voltage or power is not sufficient for
age too low feed-in (solar radiation is too low).
• Grid voltage or • The inverter checks the grid parameters before the feed-in
PV generator process begins. The length of time it takes to switch back on
voltage unsta- again differs from country to country, depending on appli-
ble. cable standards and regulations, and may be several minutes.
• The starting voltage may have been set incorrectly.
Adjust starting voltage in the Parameter menu if required.
Particular ambient When there are certain ambient conditions, the units may emit
conditions. audible noises.
• Grid interference or grid failure caused by particular loads
(motors, machines, etc.) which are either connected to
the same point on the grid or located in the vicinity of the
inverter.
• In cases of volatile weather conditions (frequent switching
between sunny and cloudy conditions) or strong solar radia-
tion, a light hum may be audible due to the increased power.
• Under particular grid conditions, resonances may form
between the unit's input filter and the grid; these may be
audible even when the inverter is switched off.
These noise emissions do not affect the operation of the
inverter. They do not lead to loss of performance, failure,
damage or to a shortening of the unit's service life.
People with very sensitive hearing (particularly children) are
able to hear the high-frequency hum caused by the inverter's
operating frequency of approximately 17 kHz.
No action
The device is too Because the temperatures inside the unit are too high, the
hot and the system inverter reduces its power to prevent damage to the unit. Note
limits the power. the technical data. Ensure that the convection cooling is not
impeded from the exterior. Do not cover the cooling fins.
Ensure sufficient cooling of the unit.
Do not cover the cooling fins.
Fault LED (red)
• Fault signal relay has switched.
ON
• Feed-in was ended due to a fault.
• The fault signal relay releases again.
OFF
• The inverter feeds back into the grid again after a
country-specific time period.
