7.8.3.4
Changing the Minimum Stop Time for the Generator
Relevant for off-grid systems
The basic procedure for changing operating parameters is explained in another section (see Section 8.6, page 113).
Procedure:
1. Select
Generator > Operation
.
2. Set the parameter
Average idle period of generator
to the desired value.
7.8.4
Configuring the Generator Request
7.8.4.1
Changing the Automatic Generator Operation
Relevant for off-grid systems
In automatic generator operation, the generator management specifies when and for how long the generator runs,
depending on the configuration.
The basic procedure for changing operating parameters is explained in another section (see Section 8.6, page 113).
Procedure:
1. Select
Generator > Generator
.
2. To deactivate automatic generator mode, set the parameter
Automatic generator start
to
Disable
.
3. To activate automatic generator mode, set the parameter
Automatic generator start
to
Enable
.
7.8.4.2
Changing a State-Of-Charge-Dependent Generator Request
Relevant for off-grid systems
If the battery reaches the lower SOC threshold, the generator management requests the generator. If the battery
reaches the upper SOC threshold during recharging, the generator management resets this generator request.
The basic procedure for changing operating parameters is explained in another section (see Section 8.6, page 113).
Procedure:
1. Select
Generator > Generator queries state of charge
.
2. Set the parameter
Generator startup battery state of charge limit
to the lower SOC threshold.
3. Set the parameter
Generator shutdown battery state of charge limit
to the upper SOC threshold.
4. Select
Generator > Generator queries state of charge > Additional time range
.
5. Set the parameter
End time range for generator request
and
Start time range for generator request
each
to the same value, e.g., to
00:00:00
. This deactivates the time-dependent generator request.
7.8.4.3
Setting a Time-Dependent Generator Request
Relevant for off-grid systems
The basic procedure for changing operating parameters is explained in another section (see Section 8.6, page 113).
