SMA Grid Guard code invalid

The SMA Grid Guard code entered is incorrect. The operating parameters are still protected and cannot be changed.

Corrective measures:

Enter the correct SMA Grid Guard code.

9003

Grid parameters locked

Changes to the grid parameters are now blocked. In order to be able to make changes to the grid parameters, from now on you must log in using the SMA Grid Guard code.

9005

Changing of grid parameters not possible > Ensure DC supply

This error can have the following causes:

The parameters to be changed are protected.
The DC voltage at the DC input is not sufficient to run the main CPU.

Corrective measures:

Enter the SMA Grid Guard code.
Ensure that at least the DC start voltage is available (green LED is flashing, pulsing or glowing).

9007

Abort self-test

The self-test (Italy only) was terminated.

Corrective measures:

Ensure that the AC connection is correct.
Restart the self-test.

10108

Time adjusted / old time

10109

Time adjusted / new time

10110

Time synchronization failed: |tn0|

No time information could be called up from the set NTP server.

Corrective measures:

Ensure that the NTP server was configured correctly.
Ensure that the inverter is integrated into a local network with Internet connection.

10118

Parameter upload complete

The configuration file was loaded successfully.

10248

[Interface]: network busy

The network is busy. Data exchange between the devices is not at an optimum and is greatly delayed.

Corrective measures:

Increase the query intervals.
If necessary, reduce the number of devices in the network.

10249

[Interface]: network overloaded

The network is overloaded. There is no data exchange between the devices.

Corrective measures:

Reduce the number of devices in the network.
If necessary, increase the data query intervals.

10250

[Interface]: package error rate [ok / high]

The package error rate has changed. If the package error rate is high, the network is overloaded or the connection to the network switch or DHCP server (router) is impaired.

Corrective measures if the package error rate is high:

Ensure that with an Ethernet connection, the network cable and the network connector are not damaged and that the network connectors are correctly plugged.
If necessary, increase the data query intervals.
If necessary, reduce the number of devices in the network.

10251

[Interface]: communication status goes to [OK / Warning / Error / Not connected]

The communication status to the network switch or DHCP server (router) has changed. An additional error message may be displayed.

10252

[Interface]: communication disrupted

There is no valid signal on the network line.

Corrective measures:

Ensure that with an Ethernet connection, the network cable and the network connector are not damaged and that the network connectors are correctly plugged.
Ensure that the DHCP server (router) and any network switches are signalizing correct operation.

10253

[Interface]: connection speed goes to [100 Mbit / 10 Mbit]

The data transfer rate has changed. The cause for the status [10 Mbit] can be a defective plug, a defective cable or the pulling or plugging of the network connector.

Corrective measures if the status is [10 Mbit]:

Ensure that with an Ethernet connection, the network cable and the network connector are not damaged and that the network connectors are correctly plugged.
Ensure that the DHCP server (router) and any network switches are signalizing correct operation.

10254

[Interface]: duplex mode goes to [Full / Half]

The duplex mode (data transfer mode) has changed. The cause for the status [Half] can be a defective plug, a defective cable or the pulling or plugging of the network connector.

Corrective measures if the status is [Half]:

Ensure that with an Ethernet connection, the network cable and the network connector are not damaged and that the network connectors are correctly plugged.
Ensure that the DHCP server (router) and any network switches are signalizing correct operation.

10255

[Interface]: Network load OK

The network load has returned to a normal range after being busy.

10282

[User group]-Login via [protocol] locked

After several incorrect login attempts, login has been blocked for a limited time. In this case, the User login will be blocked for 15 minutes, the Grid Guard login for 12 hours.

Corrective measures:

Wait until the given time has expired and then retry login.

10283

Wi-Fi module faulty

The Wi-Fi module integrated in the inverter is defective.

Corrective measures:

Contact the Service.

10284

No Wi-Fi connection possible

The inverter does not currently have a Wi-Fi connection to the selected network.

Corrective measures:

Ensure that the SSID, the Wi-Fi password and the encryption method have been entered correctly. The encryption method is specified by your Wi-Fi router or Wi-Fi access point and can be changed there.
Ensure that the Wi-Fi router or Wi-Fi access point is in range and is signalizing correct operation.
If this message is displayed often, improve the Wi-Fi connection by using a Wi-Fi repeater.

10285

Wi-Fi connection established

Connection to the selected Wi-Fi network has been established.

10286

Wi-Fi connection lost

The inverter has lost Wi-Fi connection to the selected network.

Corrective measures:

Ensure that the Wi-Fi router or Wi-Fi access point is still active.
Ensure that the Wi-Fi router or Wi-Fi access point is in range and is signalizing correct operation.
If this message is displayed often, improve the Wi-Fi connection by using a Wi-Fi repeater.

10339

Webconnect enabled

The Webconnect function has been enabled.

10340

Webconnect disabled

The Webconnect function has been disabled.

10502

Active power limit AC frequency

The inverter has reduced its power due to a too-high power frequency to ensure grid stability.

Corrective measures:

If possible, check the power frequency and observe how often fluctuations occur. If fluctuations occur frequently and this message is displayed often, contact the grid operator and request approval to change the operating parameters of the inverter. If the grid operator gives his approval, discuss any changes to the operating parameters with the Service.
