Parameter
Value
Minimum width of deep discharge protection
range
Range for protection against deep discharge as a per-
centage of the battery capacity
Within this range, the system goes into energy-saving
mode and automatically attempts to recharge the battery
from available PV energy.
Minimum width of backup power range
Range for the battery-backup function on the longest day
of the year as a percentage of the battery capacity
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

7.6.5
Changing the Battery Usage Regarding Battery-Backup Systems without
Increased Self-Consumption
Relevant for systems connected to the utility grid
14)
Set the value to June profitable when June is the month with the highest yield.
15)
Set the value to December profitable when December is the month with the highest yield.
