9 DECOMMISSIONING
DANGER! Danger of death 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 a fatal electric shock if operators touch live parts of the storage system.
CAUTION! Risk of injury due to electric shock after decommissioning.
•
Discharging of the inverter’s capacitors can take several minutes even 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.
ATTENTION! Possible damage to the unit due incorrect decommissioning.
In the event of regular decommissioning, the output must be 0 kW before the APU is decommissioned using
the ON/OFF switch. Use the SMA LCS Tool to reduce the output to 0 kW.
The DC disconnecting switch on the underside of the STPS must remain in the “ON” position, and
under no circumstances must it be set to “OFF”.
1
Reduce the output of the SMA STPS 60 to 0 kW. Open the settings in the “Power Management” section
in the SMA LCS Tool. First, save the current settings by taking a screenshot of the page. Now make the
following settings:
Limited Export enabled “Off” | Peak Load Shaving “Off” | Time of Use “Off”
Then access the active power specification in the “Inverter Parameter” > “Support Settings” > “Immedi-
ate controls” >
“Active Power [P_Ref]"
tab and set the active power to “0 %”. Please refer to SMA’s
product documentation or the website www.sma.de for further information.
Note:
The SMA LCS Tool 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 relevant product.

The 125 A NH00 fuses
9.1
or
37
(see “5.8 Connector panel” on
page 19 et. seq.) for the battery inverter can now be removed
from the left fuse holder. Then close the fuse holder.

Switch off the battery by pressing the ON/OFF switch “SWITCH”

on the APU HV1000-S (the green LED must go out).
For systems with multiple TS HV 70 Outdoors, each
APU HV1000-S has to be switched off.
