"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
Because the temperatures inside the unit are too high, the
inverter reduces its power to prevent damage to the unit.
The device is too

Do not cover the cooling fins.
When there are certain ambient conditions, the units may
emit 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 switch-
ing between sunny and cloudy conditions) or strong solar
radiation, a light hum may be audible due to the increased
power.
Particular ambient

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.

• The inverter feeds back into the grid again after a
country-specific time period.
