5.1 Generator Types
In stand-alone grid systems, (diesel) generators are often used. Choosing the right
generator is heavily dependent on the system's operating conditions. There are two
basic generator categories:
• those which can be started and stopped via electrical contacts -
autostart generators
• those which can only be operated manually -
"manual-start" generators
5.1.1 Autostart Generators
The basic function of an autostart generator is to start up and run without intervention
from the system operator. To achieve this, the generator, in addition to executing the
startup process independently, must also arrange warm-up times, cool-down times,
minimum run times and minimum stop times.
This type of generator is recommended for use in conjunction with a Sunny Island
3324/4248. Please contact your installer or system manufacturer for
recommendations regarding a specific generator.
5.1.2 Manual-Start Generators
Generators which are activated manually need to be started by the user by means
of a button or other activation procedure. These generators are structured more
simply, and generally cost less.
5.2 Generator Parameters
If you wish to use a generator with the system, then you must set the generator type,
the type of generator connection and the maximum output current delivered by the
generator. To reach the generator menu, start in the main menu (Home Screen) and
use the arrow keys to scroll to
Settings (20) , then press Enter and scroll to the
Generator Settings (24) menu. In this menu, you can change all parameter values
relating to a connected generator.
Both types of generators can produce electricity. Select your generator
carefully. If in doubt, please contact appropriate qualified personnel.
You require the installer password in order to set parameters "24-4 to 24-16".
