10.1 Cleaning the Inverter

Damage to the inverter due to the use of cleaning agents
• If the inverter is dirty, clean the enclosure, the enclosure lid, the type label and the LEDs using
only clean water and a cloth.
• Ensure that the inverter is free of dust, foliage and other dirt.

10.2 Event Messages

Event number Message, cause and corrective measures
101 to 103 Grid fault
The grid voltage or grid impedance at the connection point of the inverter is
too high. The inverter has disconnected from the utility grid.
Corrective measures:
202 to 203
Grid fault
The utility grid has been disconnected, the AC cable is damaged or the grid
voltage at the connection point of the inverter is too low. The inverter has dis-
connected from the utility grid.
Corrective measures:
If the grid voltage is outside the permissible range due to local grid conditions,
contact the grid operator. The grid operator must agree with an adjustment of
the voltage at the feed-in point or with a change of the monitored operating
limits.
If the grid voltage is permanently within the permissible range and this
message is still displayed, contact Service.
Installation Manual
• Check whether the grid voltage at the connection point of the inverter is
permanently in the permissible range.
If the grid voltage is outside the permissible range due to local grid
conditions, contact the grid operator. The grid operator must agree with
an adjustment of the voltage at the feed-in point or with a change of the
monitored operating limits.
If the grid voltage is permanently within the permissible range and this
message is still displayed, contact Service.
1. Make sure that the circuit breaker is switched on.
2. Make sure that the AC cable is not damaged.
3. Make sure that the AC cable is correctly connected.
4. Check whether the grid voltage at the connection point of the inverter is
permanently in the permissible range.
