Range Parameter Battery inverter behavior
A Self-consumption range (SlfCsmp) The battery inverter uses the batteries within
this range for increased self-consumption.
B Range for maintaining battery state of
charge (PVRes) The battery inverter checks the current SOC
every 24 hours. If the SOC is in range D,
the battery is recharged from the utility grid
until the upper limit of range B is reached. If
the utility grid is not available, the batteries
cannot be recharged.
D Minimum width of deep-discharge protec-
tion range (BatRes) The battery inverter recharges the con-
nected batteries. The recharging process
does not stop until range A is reached.
If the utility grid is not available, the battery
inverter cannot be switched on to check the
SOC of the battery. The battery inverter
and the battery are switched off.
E Lower limit of the deep-discharge protec-
tion range for disconnection (ProtRes) When this range is reached and the utility
grid is available, the battery inverter
charges the battery from the utility grid until
range A is reached.
