Event codes

There is no need to take action when an event occurs occasionally or only briefly and the device resumes operation. When an event lasts for long periods or recurs frequently, the cause must be determined and rectified.

DANGER

Risk of death due to electrical shock and discharge!

Life-threatening voltages are present in the inverter.

• Only a qualified electrician may open and perform work on the device.

In case of a permanent event, the inverter interrupts the feed-in and switches off automatically.

• Check whether the DC switch or the external DC voltage separator has been switched off.
• Check whether the event is due to a mains power failure, or whether the fuse between the feed meter and the inverter has tripped.

In case of fuse failure, notify your installer. In the event of a power failure, wait until the grid operator has rectified the fault.

If the event lasts only a short time (grid fault, overheating, overload, etc.), then the inverter will automatically resume operation as soon as the event has been resolved.

If the event persists, notify your installer or the manufacturer's customer support team.
