14 Maintenance
ATTENTION! Risk of damage to the unit and/or battery inverter if shut down improperly.
Before carrying out maintenance work, ensure that the STORAGE-67-TS-10 is taken out of operation in accor-
dance with the instructions in section “9 Shutdown“ on page 34.
NOTE: When cleaning and maintaining the STPS 60-10, always follow the specifications and instructions in
the technical documentation for the STPS 60-10.
NOTE: Local regulations and standards must be followed for any maintenance work carried out.
There is a template of a maintenance log on the USB drive
18
which you can use as an aid.
The lithium cells used by TESVOLT for the STORAGE-67-TS-10 are low-maintenance. However, to guarantee safe
operation, all plug connections must be checked by qualified specialists at least once a year and reinserted if
necessary.
The following checks or maintenance work must be carried out once a year:
• General visual inspection
• Check of all screwed electrical connections: Check the tightening torque against the values specified in the
following table. Loose connections must be re-tightened to the specified torques.
CONNECTION TORQUE
Ground SMA HV APU 6 Nm
Central grounding point 10 Nm
STPS 60-10 connections – for conductor cross-sections of 35 to 95 mm² 20 Nm
STPS 60-10 connections – for conductor cross-sections of 96 to 150 mm² 30 Nm
• Use the BatMon software to check the SoC, SoH, cell voltages and temperatures of the battery modules for
irregularities.
• Switch the STORAGE-67-TS-10 off and on again once a year.
NOTE: Take a screenshot of the “Battery” and “Cell” pages of each battery module and archive them together
with all events as a PDF.
If you would like to clean the battery cabinet, please use a dry cleaning cloth. Avoid bringing the battery con-
nections into contact with moisture. Do not use solvents of any kind.
15 Storage
To guarantee a long battery life, the storage temperature should be
kept within a range between -20°C and 50°C and the cell should be
cycled at least every six months. To minimize self-discharge during lon-
ger storage periods, the DC connecting cables should be removed
from the “BATTERy” connections

interrupts the power supply of the 24 V power supply built into the
SMA HV APU and prevents discharge of the battery.
