INTRODUCTION 

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  exceptionally  high  efficiency  and  a  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 in 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  parameters in the 
installation. 
In order to guarantee flawless 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.

For  greater  clarity,  the  device  is  referred  to  in  this  manual  as  Xtender,  unit  or  device,  when  the 
description of its functioning applies indiscriminately to different Xtender models. 
These  operating  instructions  serve  as  a  guideline  for  the  safe  and  efficient  usage  of  the  Xtender. 
Anyone who installs or uses an Xtender can rely completely on these operating instructions, and is 
bound  to  observe  all  the  safety  instructions  and  indications  contained.  The  installation  and 
commissioning  of  the  Xtender  must  be  entrusted  to  a  qualified  professional.  The  installation  and 
usage  must  conform  to  the  local  safety  instructions  and  applicable  standards  in  the  country 
concerned.
