STUDER Innotec Xtender
Installation and operating Instructions Xtender V1.3 Page 3
Congratulations! You are about to install and use a device from the Xtender range. You have chosen
a high-tech device that will play a central role in energy saving for your electrical installation. The
Xtender has been designed to work as an inverter / charger with advanced functions, which can be
used in a completely modular way and guarantee the faultless functioning of your energy system.
When the Xtender is connected to a generator or network, the latter directly supplies the consumers,
and the Xtender works like a battery charger and backup device if necessary. The powerful battery
charger has an exceptional high efficiency and power factor correction (PFC) close to 1. It
guarantees excellent battery charging in all situations. The charge profile is freely configurable
according to the type of battery used or the method of usage. The charge voltage is corrected
depending on the temperature, thanks to the optional external sensor. The power of the charger is
modulated in real time dependent according to the demand of the equipment connected at the
Xtender output and the power of the energy source (network or generator). It can even temporarily
backup the source if the consumer demand exceeds the source capacity.
The Xtender continuously monitors the source to which it is connected (network or generator) and
disconnects itself immediately if the source is missing, disturbed or does not correspond to the
quality criteria (voltage, frequency, etc.). It will then function in independent mode, thanks to the
integrated inverter. This inverter, which has an extremely robust design, benefits from STUDER
Innotec’s many years of experience and expertise in this area. It could supply any type of load
without faults, enjoying reserves of additional power that is unmatched on the market. All your
equipment will be perfectly provided with energy and protected from power outages in systems
where energy supply is unpredictable (unreliable network) or voluntarily limited or interrupted, such
as hybrid installations on remote sites or mobile installations.
The parallel and/or three-phase network operation of the Xtender offers modularity and flexibility and
enables optimum adaptation of your system to your energy requirements.
The RCC-02/03 control, display and programming centre (optional) enables optimum configuration
of the system and guarantees the operator continuous control for all important configurations in the
installation.
In order to guarantee perfect commissioning and functioning of your installation, please read this
manual carefully. It contains all the necessary information relating to the functioning of the inverters /
chargers in the Xtender series. The setting up of such a system requires special expertise and may
only be carried out by qualified personnel familiar with the applicable local regulations.
