Messages on the display and the "Fault" 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.

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
voltage unsta- on again differs by country according to applicable stand-
ble. ards and regulations and can take 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
conditions. 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.
• Under certain grid conditions, resonances may form
between the unit's input filter and the grid, which 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 efficiency, 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 invert-
er's operating frequency of approximately 17 kHz.

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.
limits the power. Note 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.
