Replacing an SMA Energy Meter in a System with a Sunny Island Inverter
1. Write down the serial number indicated on the type label of the new SMA Energy Meter.
2. Disassemble the SMA Energy Meter to be replaced (see the SMA Energy Meter manual).
3. Mount the new SMA Energy Meter and commission it (see the SMA Energy Meter manual).
4. Transfer the serial number of the new SMA Energy Meter to the inverter using Sunny Explorer:
• Log into the Speedwire system in Sunny Explorer and select the system in the system tree.
• If you are using the SMA Energy Meter as purchased electricity meter and feed-in meter, proceed as follows:
– Select Settings > AC side > [Edit].
– Enter the serial number of the new SMA Energy Meter in the Measuring interface 1 area in the field
Serial number and then select [Save]. The saving process may take a few minutes.
• If you are using the SMA Energy Meter as PV production meter, proceed as follows:
– Select Settings > AC side > [Edit].
– Enter the serial number of the new SMA Energy Meter in the Measuring interface 2 area in the field
Serial number and then select [Save]. The saving process may take a few minutes.
12.3 Replacing the Battery Pack Smart Energy
Procedure on Receipt of a New Battery Pack
• Disassembling the Defective Battery Pack
• Mounting the New Battery Pack and Connecting It to the Inverter
• Packing the Defective Battery Pack and Organizing Its Return
Disassembling the Defective Battery Pack
1. Open the packaging of the new Battery Pack and remove the delivery documents and the return note. Be careful
when handling the packaging as you will need it later for packing the defective Battery Pack.
2. Compare the serial number on the return note with the serial number of the defective Battery Pack. The serial numbers
must be identical.
3. Keep the delivery documents of the new Battery Pack and the return note for the defective Battery Pack in a safe
place. You will need the return note later to prepare the defective Battery Pack for collection.
4. Disconnect the inverter from all voltage sources (see the inverter manual at www.SMA-Solar.com).
5. Hold the defective Battery Pack by the side handles and slide it to the left of the wall mounting bracket up to the stop.
This deactivates the lift-off protection of the Battery Pack and gives you more room to pull out the cables.
6. Remove the data cable from the defective Battery Pack. Press the lateral brackets in and pull the plug out of the pin
connector.

Danger to life due to high voltages on the Battery Pack
Lethal voltage is present at the pin connector for the power cable. Reaching into the pin connector for the power cable
can result in lethal electric shock.
• Prior to performing any work on the inverter and on the Battery Pack, always disconnect the inverter from all
voltage sources (see the inverter operating manual at www.SMA-Solar.com).
• The Battery Pack may only be mounted and installed by qualified persons with appropriate qualifications
(for information on the qualifications of the qualified persons, see the operating manual at www.SMA-Solar.com).
• Do not open the Battery Pack and leave the protective caps on the pin connectors of the new Battery Pack until
the inverter cables are connected to the new Battery Pack.
