Changing the Minimum Stop Time for the Generator

1. Log in to the communication product as Installer (see the user manual of the communication product) or
switch to expert mode on the Sunny Remote Control (see the Sunny Island operating manual).
2. Select the parameter Minimum idle time of the generator / 234.09 GnStpTmMin and set to the desired value.

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. Log in to the communication product as Installer (see the user manual of the communication product) or switch to
expert mode on the Sunny Remote Control (see the Sunny Island operating manual).
2. To deactivate automatic generator mode, select the parameter 235.01 GnAutoEna / Automatic generator start
and set it to Disable.
3. To activate automatic generator mode, select the parameter 235.01 GnAutoEna / Automatic generator start
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. Log in to the communication product as Installer (see the user manual of the communication product) or switch to
expert mode on the Sunny Remote Control (see the Sunny Island operating manual).
2. Select the parameter Battery state of charge limit for generator start / 235.03 GnSocTm1Str and set it to
the lower SOC threshold.
3. Select the parameter Battery state of charge limit for generator disconnection / 235.04 GnSocTm1Stp and
set it to the upper SOC threshold.
4. Set the parameter End time additional time period generator request / 235.07 GnTm1Str and Start time
additional time period generator request / 235.08 GnTm2Str to the same value, e.g., 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 time periods. For each time period, you set
which conditions there are for the generator request (see Section 9.3 "Setting Time-Dependent Functions",
page 100). 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 time periods 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 time period 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 time period, the other settings for the generator
request, e.g., the time-dependent generator request, apply.
