Product Description

The Xtender series provides unmatched freedom of use due to its many functions. In a basic application it offers a total package : the functions of inverter, battery charger, transfer system and assistance to the source. These functions can be combined and controlled in a totally automatic way for exceptional ease and optimal management of available energy.

The Xtender is equipped with a command entry and 2 configurable auxiliary contacts. This allows automatic control of a genset or a load shedding when the battery voltage is too low. This flexibility makes it possible to implement special functionalities necessary for a good energy management in standalone power systems.



  • Outstanding efficiency and overload.
  • Perfect management and limitation of AC sources.
  • Power shaving of consumption peaks.
  • Active filtering of load steps on a genset.
  • Automatic protection of sources against overload.
  • Parallel and three-phase setting, up to 9 units (8.1kW).
  • Powerful multi-stage PFC charger.
  • Ultra-short transfer time (from 0 to 15ms max.)
  • Automatic and efficient stand-by
  • 2 programmable auxiliary contacts (optional on the XTS)
  • Compatible with AC coupling
  • XTS electronically protected against reverse polarity
  • Display, programming and data logging via optional remote control.
  • RS-232 communication for remote monitoring.
