• Increased self-consumption range (SlfCsmp)
You determine the percentage of the battery capacity that is to be used for increased self-consumption on the
shortest day of the year.
• Range for battery-backup function (BURes)
You specify the percentage of the battery capacity that is to be used for the battery-backup function on the longest
day.
The longer the days become, the more the SlfCsmp range automatically increases and the BURes range decreases.
The range for increased self-consumption reaches its maximum on the longest day. This results in the seasonal
progression of the ranges.

Self-consumption range (SlfCsmp)
11)
The
SlfCsmp
range applies to the shortest day of the
SlfCsmp
range is used and the
BURes
range in-
creased accordingly.
The Sunny Island uses the battery for in-
creased self-consumption.
