20 WB3-5TL-21-IA-en-10 Installation Manual
4.4 Bluetooth
The inverter is equipped as standard with a Bluetooth interface and can communicate with special
SMA communication products or other inverters (for information on supported products, see
www.SMA-Solar.com).
If you would like to communicate via Bluetooth, you can protect the inverter with one plant password
for the user and one plant password for the installer.
All inverters are delivered with a standard plant password for the user (0000) and a standard plant
password for the installer (1111). To protect the plant from unauthorized access, you must change
the plant passwords using Sunny Explorer (for information on changing the plant password, refer to
the Sunny Explorer help).
If you do not wish to communicate via Bluetooth, deactivate the Bluetooth communication
(see Section 7.3 "Setting the NetID", page 45).
4.5 Slot for Communication Interface
The inverter can optionally be fitted with an extra communication interface (e.g. RS485).
This communication interface enables the inverter to communicate with special SMA communication
products (for information on supported products, see www.SMA-Solar.com). The communication
interface can be retrofitted or installed by default with the respective order.
Depending on the type of communication, RS485, Bluetooth, or Speedwire, the parameters and
messages are displayed differently on the communication products.
4.6 Operating Parameters
Various operating parameters control the functionality of the inverter. You can only adjust all
operating parameters of the inverter, excluding the country data set, using an SMA communication
product (see Section 8.7). You can adjust the country data set before commissioning or within the first
ten feed-in hours via two rotary switches in the inverter (see Section 7.2).
Example: How the country data set parameter is displayed
• For communication with RS485: CntrySet parameter
• For communication with Bluetooth or Speedwire: Set country standard parameter
