10 Troubleshooting

Bluetooth Connection

Problem Cause and corrective measures

System search

Connection to the Bluetooth

system failed.

• Connection to the Bluetooth system is too weak.

– Reduce the distance to the devices and try to reconnect.

• There are already four masters connected to the Bluetooth

system.

–

Remove one master and try to reconnect.

• There are already two nodes connected to the device

through which you wish to connect to the Bluetooth system.

–

Select another device or remove another

communication device, and try to reconnect.

System search

The displayed device names

and NetIDs are not up-to-date.

• Depending on the Bluetooth stack used, it is possible that

changes to the NetID or the device name are not correctly

recognized by an inverter.

Proceed as follows:

1. Close the Bluetooth stick software, if applicable.

2. Briefly remove and reinsert the Bluetooth stick.

3. If necessary, restart the Bluetooth stick software.

4. Repeat the system search in Sunny Explorer.

System search

The device address is

displayed, but the device name

is not displayed.

• Sunny Explorer has not finished reading the device name

from the device.

– Repeat system search so that Sunny Explorer updates

the device name.

Inverter is not accessible

After setting parameters for

communication via Bluetooth,

the inverter cannot be accessed

for an extended period.

• When setting parameters that regulate the Bluetooth

connection (e.g. parameters for the transmission power and

country parameters), communication via Bluetooth is

interrupted for some time because the inverter is carrying out

a restart of the communication interface.

– Wait until the inverter has completed its restart.

The inverter will then be accessible again.
