8 Troubleshooting

8.1 General Errors

Problem Cause and corrective measures

The inverter with Piggy-Back

cannot be accessed.

There is no Speedwire connection.

Corrective measures:

• Ensure that all network cable plugs are inserted and locked.

• Ensure that all inverters in the plant are in operation.

• Ensure that the plant router is switched on.

• Ensure that the Piggy-Back is connected correctly

(see Section 5.3).

• Ensure that the Cluster Controller is connected to the local

plant network (see Cluster Controller installation manual).

The firmware version of the inverter is not supported

(see Section 2.2).

Corrective measures:

• An inverter firmware update can only be carried out by

SMA Service. If your inverter is in need of a firmware

update, contact the SMA Service Line (see Section 10).

The software version of Sunny Explorer is older than version 1.05.

Corrective measures:

• Download Sunny Explorer from software version 1.05 from

www.SMA-Solar.com and install.

Firewall or IP filter settings are not correct.

Corrective measures:

• Adjust the firewall or IP filter settings (see firewall or router

manual).

The Piggy-Back does not have a valid IP address.

Corrective measures:

• Make sure DHCP is enabled for the router.

Inverters with retrofitted Piggy-Back shut down overnight. It is

therefore not possible to establish any connection to these

inverters.

As soon as the inverters switch on in the morning, they will be

accessible again.

Piggy-Back update does not

initialise.

The feed-in power of the inverter is less than 50 W.

Corrective measures:

• Carry out update once the feed-in power of the inverter is at

least 50 W.
