Range Explanation of the range and parameters
C Deep discharge protection range (BatRes)
This range can only be reached when the utility grid fails.
The BatRes range applies to the longest day of the year
with seasonal adjustment (see Section 7.6.4.1,
page 74). If seasonal adjustment is deactivated, the Ba-
tRes range is increased accordingly.
Battery > Ranges of application > Minimum width

D Deep discharge range (ProtRes)
This range can only be reached when the utility grid fails.
Battery > Ranges of application > Lower lmt deep

Behavior of the Sunny Island inverter
If a utility grid is available, the Sunny Island
charges the battery using nominal power
from the utility grid.
When this range is reached, the Sunny Island
switches off in order to protect the battery.
When the utility grid is available again, the
system must be charged manually.
