You can now recommission the storage system in accordance with section “8 Commissioning” on page
36.
10
In the event of a restart, the APU HV1000-S queries the number of modules now detected on the dis-
play. If the number is correct, confirm this by tapping twice on the marking to the right of the display.
11
After this, start recommissioning the system using the SMA LCS Tool (adjusting the new voltage limits).
Sign into the SMA LCS Tool using your “Grid Guard” code. After starting recommissioning, go through
the commissioning procedure and select “Tesvolt 16 modules”. During recommissioning, follow the
documentation for the SMA LCS Tool.
Adjusting the battery voltage using the SMA LCS Tool
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.
1
Enter your
SMA Grid Guard Code
in the “Service” > “Grid Guard” tab. If you do not have a code, please
contact the SMA Service Line.
2
Access the active power specification in the “Inverter Parameter” > “Support Settings” > “Immediate
Controls” >
“Active Power [P_Ref]”
tab and set the active power to “0
%” > Put the STPS on standby
and save the setting (“Save”).
3
Make the following settings under the “Power Management” tab:
Limited Export enabled “Off” | Peak Load Shaving “Off” | Time of Use “Off”.
4
Determine the ACTUAL DC voltage using the APU or STPS display or the SMA LCS Tool and compare
this with the TARGET voltage of 700.0 V (14 battery modules with 50.0 V each).
Note:
The stored energy must be prevented from being fed back into the utility grid. For this reason,
the energy fed in from the battery storage system must not exceed the current consumption in the
local power supply.
5
If you have to reduce the voltage of the TS HV 70 Outdoor (discharging), enter a value between
0 and 100 % [positive number] for
“Active Power [P_Ref]”
.
6
If you have to increase the voltage of the TS HV 70 Outdoor (charging, enter a value between
0 and -100 % [negative number] for
“Active Power [P_Ref]”
.
7
Monitor charging or discharging to the target voltage of 700.0 V.
8
When the target voltage is reached, slowly reduce the charging/discharging power to 0 %.
9
Compare the voltage of one of the existing modules in the storage system with the module voltage of
the expansion modules. Both values must be 50.0 +/-0.1 V.
10
Adjust the voltage of the storage system until the new and original modules are at the same voltage.
