In a hybrid system it is very important to have an automatic management of the backup generator, according to different conditions. The main goal of the backup generator is to protect the battery from deep discharge. At Studer we know that the protection of the battery is critical; therefore, we have preconfigured the automatic start of a generator according to battery voltage using the xtender’s Auxiliary Contact 1 as factory settings. You only need to cable the xtender’s Auxiliary Contact 1 and the generators’ automatic start. The preconfigured factory settings will do the rest, starting your generator when the battery voltage is low. When your battery is charged, the Auxiliary Contact 1 will be deactivated and your generator will turn off automatically.
Your xtender system is factory-configured for easy integration of a backup generator to protect your battery. The battery voltage settings are preconfigured by us. We recommend adjusting the battery voltage settings in line with your system design and the battery manufacturer’s recommendations. It is also possible to configure the xtender to automatically start the generator in response to other conditions and events via the xtender settings menu. Most generators feature an automatic start function. If you have a generator with a three-wire connection, you can still configure the system for automatic generator start-up using the extended functions of Auxiliary Contacts 1 and 2.
