 DECOMMISSIONING
DANGER! Risk of injury due to electric shock after decommissioning.
Large parts of the battery system are still under full voltage even after decommissioning, meaning
there is a risk of an electric shock if operators touch live parts of the storage system.
DANGER! Risk of injury due to electric shock after decommissioning.
• Discharging the capacitors in the battery inverter can take several minutes after switching off. For
this reason, please wait 15minutes until the system has largely discharged.
• The DC auxiliary circuit is not completely voltage-free after decommissioning; the voltage is merely
low (U
DC
≤ 60V), meaning a fatal electric shock can no longer occur if operators touch live parts of
the DC auxiliary circuit.
WARNING! Possible damage to the unit due to incorrect decommissioning.
For standard decommissioning, the output must be 0kW before the APU is decommissioned using the On/
Off switch as this may otherwise damage the APU.
NOTE: The SMA Sunny Island is an SMA product. For this reason, TESVOLT cannot guarantee the
accuracy of information provided about this and other products belonging to SMA. Binding information
can only be found in SMA’s valid product documentation for the product.
1
First, stop the SMA Sunny Island. To do this, press the start/stop
button
A
on the SMA Sunny Island and hold this down until the
control LED on the SMA Sunny Island lights up orange.
2
Next, press the OFF button
C
on the SMA Sunny Island and hold this down until an audible signal is
heard.
3
Switch off the battery (press the green-lit On/Off switch on the
APU LV; the green LED must go out).
In the case of systems with several TS 48 V units, each APU LV
must be switched off.
4
On the APU, disconnect the DC connecting cables
5.1
and
5.2
from the unit at the CHARGER connec-
tion

.
5
Wait 15 minutes until the system is largely voltage-free, as the capacitors in the battery inverter take
several minutes to discharge.
