Parameters for battery use:
If the values for the battery usage ranges are incorrect, no adjustment is possible
If all battery usage ranges combined exceed 100%, the parameters for battery usage cannot be set.
• Ensure that all battery usage ranges combined result in the value 100%.
Parameter
Value
Lower lmt deep disch. protect range prior shut-
down
Range for protection during deep discharge as a percent-
age of the battery capacity
Minimum width of deep discharge protection
range
Range for protection against deep discharge on the long-
est day of the year as a percentage of the battery capac-
ity
Within this range, the system goes into energy-saving
mode and automatically attempts to recharge the battery
from available PV energy.
The range remains constant year-round when seasonal
adjustment is deactivated.
Width of the range for conserving battery state of
charge
Range for maintaining the state of charge of the battery
as a percentage of the battery capacity
Minimum width of own consumption range
Range for increasing self-consumption on the shortest day
of the year as a percentage of the battery capacity
When seasonal adjustment is deactivated, this value is
used year-round for increased self-consumption.
Highest-yielding month for battery utilization
range:
June profitable
for northern hemisphere
9)
December profitable
for southern hemisphere
10)
Season operation active
No
for no seasonal adjustment

7.6.4.3
Changing the Battery Usage Regarding Battery-Backup Systems with
Increased Self-Consumption
Relevant for systems connected to the utility grid
Ranges for battery use:
2 ranges can be adjusted seasonally in battery-backup systems with increased self-consumption:
9)
Set the value to June profitable when June is the month with the highest yield.
10)
Set the value to December profitable when December is the month with the highest yield.
