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. If the generator has an autostart function, select the parameter Generator request / 234.07 GnStrMod and set
to Autostart.
3. If the generator does not have an autostart function, select the parameter Generator request /
234.07 GnStrMod and set to Manual.

Configuring Generator Run Times

8.4.3.1

Changing the Warm-Up Time for the Generator

Relation between warm-up time and termination of generator start:
The generator management measures the time between the generator start and the beginning of the warm-up
time. If a maximum time is exceeded, the generator management terminates the generator start. The maximum time to
start termination is double the warm-up time plus an additional two minutes.
With some generator types, the generator only switches the voltage to the output of the generator after the internal
warm-up time has expired. During this time, the generator management is unable to recognize a valid generator voltage.
If the warm-up time is set too low, the generator management terminates the generator start before the internal warm-up
time has expired.
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 Generator warm-up time / 234.12 GnWarmTm.
3. Set the selected parameter according to the generator properties.

8.4.3.2

Changing the Minimum Run 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 run time of the generator / 234.08 GnOpTmMin and set to the desired value.
8.4.3.3

Changing the Power-Down Time for the Generator

Internal shut-off delay of the generator
Generators may have an internal shut-off delay which is activated only once the generator request has been
removed. Note that this internal shut-off delay increases the actual power-down time.
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 Cool-down time of the generator / 234.10 GnCoolTm and set to the desired value.
