Setting the NetID

Qualified person

If the inverter is equipped with BLUETOOTH, you can set the NetID of the inverter. By default, the NetID is set to 1 for all SMA inverters and SMA communication products with BLUETOOTH. If your PV system consists of an inverter and a maximum of one further BLUETOOTH device (e.g. computer with BLUETOOTH interface or SMA communication product), you can leave the NetID set to 1.

You must change the NetID in the following cases:

  • If your PV system consists of one inverter and two other BLUETOOTH devices (e.g. computer with BLUETOOTH interface and SMA communication product) or of multiple inverters with BLUETOOTH, you must change the NetID of your PV system. This enables you to communicate using multiple BLUETOOTH devices.

  • If another PV system with BLUETOOTH is located within 500 m of your PV system, you must change the NetID of your PV system. This will help keep both PV systems separate.

  • If you do not wish to communicate via BLUETOOTH, deactivate the BLUETOOTH communication on your inverter. This will protect your PV system from unauthorized access.

All BLUETOOTH devices in a PV system must have the same NetID. You can set a new NetID in the inverter by means of the rotary switch C.

Procedure:

  1. DANGER

    Danger to life due to high voltages

    1. Ensure that the inverter is disconnected from all voltage sources ( > Disconnecting the Inverter from Voltage Sources).

  2. To set a new NetID, set the rotary switch C to the determined NetID using a flat-blade screwdriver (blade width: 2.5 mm).

  3. To deactivate communication via BLUETOOTH, set the rotary switch C to position 0 using a flat-blade screwdriver (blade width: 2.5 mm). This will protect your PV system from unauthorized access.
  • The inverter will adopt the setting after commissioning. This can take up to five minutes.
