Network busy > Network overloaded

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

Corrective measures:

  • Reduce the number of devices in the network.

  • If necessary, increase the data query intervals.

  • If necessary, reduce the number of devices in the network.

10250

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 disturbed.

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.

  • If necessary, increase the data query intervals.

  • If necessary, reduce the number of devices in the network. 12 Troubleshooting SMA Solar Technology AG 78

10251

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

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

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

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

10283

WLAN module faulty

The WLAN module integrated in the inverter is defective.

Corrective measures:

10284

No WLAN connection possible

The inverter does not currently have a WLAN connection to the selected network.

Corrective measures:

  • Ensure that the SSID, the WLAN password and the encryption method have been entered correctly. The encryption method is specified by your WLAN router or WLAN Access Point and can be changed there.

  • Ensure that the WLAN router or WLAN Access Point is in range and is signalizing correct operation.

  • If this message is displayed often, improve the WLAN connection by using a WLAN repeater.

10285

WLAN connection established

Connection to the selected WLAN network has been established.

10286

WLAN connection lost

The inverter has lost WLAN connection to the selected network.

Corrective measures:

  • Ensure that the WLAN router or WLAN Access Point is still active.

  • Ensure that the WLAN router or WLAN Access Point is in range and is signalizing correct operation.

  • If this message is displayed often, improve the WLAN connection by using a WLAN repeater.

10287

10339

Webconnect enabled

The inverter can communicate with Sunny Portal without an additional SMA communications product (e.g. Sunny Home Manager).

10340

Webconnect disabled

The Webconnect function has been switched off. This means that the inverter can not communicate with Sunny Portal without an additional SMA communications product (e.g. Sunny Home Manager).

  • If the inverter is to communicate with Sunny Portal without an additional SMA communication product, switch the Webconnect function on.
