Corrective measures:

  • Disconnect the loads, start the generator, start the Sunny Island and charge the battery.

9331

Battery error

Battery voltage in the Sunny Island at Lxx is above the permissible measurement range.

Corrective measures:

  • Check whether the value set for the parameter Battery voltage is above 65.0 V. If the value is above 65.0 V, check the settings of the DC sources and ensure that the battery capacity is sufficient. Observe the technical data for the battery at the DC connection.

  • Ensure that the DC sources are correctly connected and configured.

  • For off-grid systems: ensure that all SMA inverters are configured to the country data set for stand-alone mode.

9332

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 impaired.

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

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

10252

Communication impaired

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]
