5 LCS-Tool
FNN NOTE
In Germany, according to NN note
"Connecting and operating storage units in low
voltage networks" (October 2016), systems
eligible under the IT scheme in accordance
with EEG and KWKG are not allowed to feed
energy from storage units into the utility grid. To
ensure this, the input value for Consumption
Limit is not allowed to be negative.
Procedure:
1. Open the LCS-Tool.
2. Log in as an Installer.
3. Call up the menu Setup.
4. In the Power Management menu enable the
function Peak Load Shaving. To do so, select
the option button On.
5. Enter the desired value for SoC threshold.
6. Under Limit over Soc threshold, enter the
thresholds for the grid feed-in and grid-supplied
power for a battery state of charge that is
above the defned setpoint.
– Consumption Limit: limiting value for
grid-supplied-power
– Feed-in limit: limiting value for the grid
feed-in
7. Under Limit under Soc threshold, enter the
thresholds for the grid feed-in and grid-supplied
power for a battery state of charge that is
below the defned setpoint.
8. Select [Save] to save the changes.

5.2.11 Setting Time of Use

INFORMATION
This function can only be used in battery
storage systems.
• Recommendation: In PV systems, leave
this function disabled.
The Time of Use function makes it possible to reduce
energy costs by effectively using different electricity
tariffs throughout the day. or this purpose, the
38 IMVIOBOX-IA-xx-18
SMA Solar Technology AG
LCS-Tool enables the defnition of periods when the
battery can be charged at low cost and periods
when the battery is discharged when energy costs
are high.
The battery can be charged up to 60 kW.
In the standard confguration, the battery can be
discharged with 60 kW. If the system is equipped
with the Storage Extension Kit TV-10, the battery can
be discharged with 75 kW.
Battery behavior during the charging period:
• The battery will be charged at the specifed
charging power. At night, the energy will be
directly drawn from the utility grid.
If there is unused PV energy available for
charging the battery during the day, the missing
energy will be drawn from the utility grid.
• Discharging and controlling the battery are
blocked for the charging period.
Battery behavior during the discharging
period:
• If power is drawn at the point of
interconnection, the battery inverter attempts to
compensate for this by discharging the battery.
• If excess PV power is being fed in at the point
of interconnection, the battery inverter attempts
to balance this by charging the battery.
• If the maximum charging power of the battery
system has been exceeded during the
discharging period, power is fed into the utility
grid.
• If the maximum discharging power of the
battery system has been exceeded, power is
drawn from the utility grid. This power is not
used to charge the batteries.
In order to optimally adapt the charging behavior to
the different conditions over the course of the year,
the settings can be made separately for two periods
(Season 1 and Season 2). or these periods,
separate charging profles can be de f ned for each
day of the week. Settings for 30-minute intervals or
for the entire day can be made.
