8.4.4 Configuring the Generator Request
8.4.4.1 Changing the Automatic Generator Operation
In automatic generator operation, the generator management specifies when and for how long the generator
runs, depending on the configuration.
Procedure:
1. Switch to installer mode on the Sunny Remote Control (see the Sunny Island inverter operating manual).
2. To deactivate automatic generator mode, select the parameter 235.01 GnAutoEna and set it to Disable.
3. To activate automatic generator mode, select the parameter 235.01 GnAutoEna and set it to Enable.
8.4.4.2 Changing a State-Of-Charge-Dependent Generator Request
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.
Procedure:
1. Switch to installer mode on the Sunny Remote Control (see the Sunny Island inverter operating manual).
2. Select the parameter 235.03 GnSocTm1Str and set it to the lower SOC threshold.
3. Select the parameter 235.04 GnSocTm1Stp and set it to the upper SOC threshold.
4. Set the parameters 235.07 GnTm1Str and 235.08 GnTm2Str to the same value, e.g. both to 00:00:00.
This deactivates the time-dependent generator request.
8.4.4.3 Setting a Time-Dependent Generator Request
The time-dependent generator request divides the day into two intervals. For each interval, you set which
conditions there are for the generator request (see Section 9.3 "Setting Time-Dependent Functions", page 92).
In this way, you can, for example, set the generator not to start at night. This ensures that the noise pollution produced
by the generator takes place during the day whenever possible.
Both intervals each have a lower and an upper SOC threshold. If the battery reaches the lower SOC threshold,
the generator management requests the generator. When the battery reaches the upper SOC threshold during
recharging, generator management resets this generator request. The following settings are possible for the SOC
thresholds:
• The lower SOC threshold is lower than the upper SOC threshold.
The generator is requested during this interval depending on the state of charge.
• The lower SOC threshold is higher than or equal to the upper SOC threshold.
The generator is not started depending on the state of charge. In this interval, the other settings for the generator
request, e.g. the time-dependent generator request, apply.
