10.1 Replacement Procedure when Replacing Different Devices
10.2 Replacing an Inverter with RS485 in the Sunny WebBox
Procedure:
• Replacing an Inverter in the Sunny WebBox
• Replacing an Inverter in the Sunny Portal System
Replacing an Inverter in the Sunny WebBox
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 the user interface of the Sunny WebBox.
• Select PV System > Devices and select the inverter to be replaced.
• Select the tab Overview and read off and write down the value in the Energy total row.
3. If you are using Sunny Portal you must transfer all data saved to the inverter and to the Sunny WebBox to
Sunny Portal before replacing the inverter.
• Select WebBox > Info in the Sunny WebBox user interface.
• Select [Upload] in the Last portal upload row.
☑ The value Sunny Portal buffer load is 0%.
4. Decommission the inverter to be replaced (see the inverter manual).
5. If you are retrofitting your new inverter with RS485 communication, install the RS485 interface in the inverter and
commission it (see RS485 interface manual).
6. Commission the new inverter (see inverter manual).
7. Detect the new inverter with the Sunny WebBox:
• Log into the user interface of the Sunny WebBox.
• Select PV system > Detection.
• Enter the number of newly connected inverters in the field Total number of devices to be detected and select
[Start detection].
• When the detection of the connected inverters is completed, select [OK].
8. Transfer the noted energy yield of the inverter to be replaced to the new inverter. Be aware that the parameter
displayed is dependent on the inverter device type:
• In the Sunny WebBox user interface select the inverter in the system tree.
• Select the tab Parameters.
• Call up the parameter for the energy yield of the new inverter. In the list of parameters, search for the parameter
with the kWh unit in the Unit column.
• In the column Value, enter the noted energy yield of the inverter to be replaced in the field.
• Select [Save].
