REPLACING THE
BATTERY PACK SMART ENERGY

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 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.

Procedure on Receipt of a New Battery Pack

• Disassemble the defective Battery Pack.

• Mount the new Battery Pack and connect it to the inverter.

• Pack the defective Battery Pack and organize its return.

Disassembling the Defective Battery Pack

1. Op en the pac kag ing of t he new Bat ter y P ack and re mov e th e delivery documents and the return
note. Be careful when handling the packaging as you will need it later for packaging 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 d efective Battery Pack. Press the lateral brackets in and pull the
plug out of the pin connector.

7. Remove the power cable from the defective Battery Pack. Turn the plug lock to the left until the
plug releases and then pull the plug out of the pin connector.

8. If the protective caps of the pin connectors for the data cable and the power cable are
available, use them to cover the corresponding pin connectors of the defective Battery Pack.

9. Insert the data cable and power cable into the bracket on the left-hand side of the inverter.

10. Remove the defective Battery Pack vertically upwards from the wall mounting bracket.

Mounting the New Battery Pack and Connecting It to the Inverter

1. Remove the new Battery Pack from the packaging and put the packaging aside. Be careful
when handling the packaging as you will need this later for packaging the defective
Battery Pack.

2. Hang the new Battery Pack to the left o f the inverter in the wall mounting bracket. The right-hand
side of the Battery Pack must be flush with the hook-in position marked on the wall mounting
bracket.

3. Remove the protective caps from the pin connectors for the data cable and power cable and
retain them for possible decommissioning.

4. If the protective caps of the defective Battery Pack are no longer available, place the protective
covers of the new Battery Pack on to the pin connectors of the defective Battery Pack.

5. Release the data cable and the power cable from the bracket on the inverter.

6. Insert the power cable plug in the pin connector for the power cable. Insert the plug into the pin
connector and turn the lock to the right until the plug snaps into place.

7. Ensure that the plug is securely in place.

8. Connect the data cable for communication between the inverter and the Battery Pack to the
D-sub plug of the Battery Pack.

9. The plug snaps audibly into place.

10.

Danger of crushing if the Battery Pack is jolted

• Grip the Battery Pack by the handles and carefully push it to the right as far as the stop.

11. Position the protective cover over the Battery Pack. The brackets on the right-hand side of the
protective cover must engage with the guides on the left of the inverter enclosure. Then press the
left side of the protective cover down onto the Battery Pack until it snaps into place.
