11.2 BLUETOOTH System with Sunny Explorer
11.2.1 Replacing an Inverter with BLUETOOTH in Sunny Explorer
1. Read the serial number of the inverter to be replaced off the type label and write it down.
2. Determine the energy yield of the inverter to be replaced:
• Log into Sunny Explorer at the BLUETOOTH system.
• Select the inverter to be replaced in the system tree.
• Select Overview and read off and write down the value in the Total yield row.
3. Decommission the inverter to be replaced (see the inverter manual).
4. If you retrofit the new inverter with BLUETOOTH communication, install the BLUETOOTH interface in the inverter and
commission (see the BLUETOOTH interface manual).
5. For a new inverter, set the NetID of the system:
• For inverters with integrated BLUETOOTH, turn the rotary switch NetID on the inverter using a screwdriver (blade
width 2.5 mm) to the NetID of the system (see the inverter manual).
• For inverters with retrofitted BLUETOOTH interface, turn the rotary switch NetID on the inverter using a
screwdriver (blade width 2.5 mm) to the NetID of the system (see the interface manual).
6. Commission the new inverter (see inverter manual).
7. Log into Sunny Explorer at the BLUETOOTH system.
☑ Sunny Explorer automatically detects the new inverter. The new inverter is displayed with a padlock symbol in
the system tree.
8. Adjust the system passwords of the existing BLUETOOTH system for the new inverter:
• Set up a new BLUETOOTH system in Sunny Explorer and log in as Installer using the password for the user
group Installer that has been set up in the new inverter.
• Select the BLUETOOTH system in the system tree.
• Select Settings > User rights (All devices) > [Edit].
• Enter the system password for the respective user group that has been set up for the BLUETOOTH system to which
you wish to add the new inverter.
• Select [Save]. The saving process may take a few minutes.
9. Log into Sunny Explorer at the BLUETOOTH system to which you wish to add the new inverter.
☑ The new inverter is displayed without a padlock symbol in the system tree.
10. Set the the noted energy yield of the inverter to be replaced in the new inverter:
• In Sunny Explorer, select the new inverter in the system tree.
• Select Settings > AC side > [Edit].
11. Enter the noted energy yield of the inverter to be replaced in the field Set total yield and then select [Save].
The saving process may take a few minutes.
