Remote control and
programming centre RCC-03
Thanks to its graphic display it provides many understandable indica-
tions on the state of the system.
The remote control memorises and displays the events that occurred
on an installation and so it does anticipate the problems that might
appear.
It gives access to the many adjustable parameters of the Xtender like the
setting of the charge curve of the battery, the programming of the auxi-
liary relays or even, among others, to a lot of operation options.
A place is dedicated to a SD card which will allow the parameters memo-
rising, the data transfer or the software update.
Battery temperature sensor BTS-01
This sensor enables to accurately adapt the charge thresholds to the
battery temperature.
Communication module 3ph and parallel PEM-01
Allows the setting in parallel or the implementation of a 3-phase system
even when only a single-phase source is available.
Communication cable for 3ph and parallel
CAB-RJ45-2 (2 m)
Allows the setting in parallel or the implementation of a 3-phase system
even when only a single-phase source is available.

Xtender XTH
3000-12, 5000-24, 6000-48, 8000-48
The serie Xtender offers a new function, the Smart-Boost,
which enables to add the inverter power to another sour-
ce, like for instance a genset or the shorepower, even
in case of asymetric loads. It is also possible to add an
Xtender to almost any other existing inverter in order to
increase the power available.
The products of the Xtender-Series provide an unmat-
ched freedom of use, thanks to their many functions. In
a basic application, they offer together the functions of
inverter, battery charger, transfersystem and assistance to
the source.
These functions can be combined and controlled in a to-
tally automatic way for an exceptional comfort and an
optimal management of the available energy.
By the implementation of several units, it is possible to
create a 3-phase source or to set them in parallel to in-
crease the power available. Up to 9 inverters of the serie
Xtender shall therefore be combined together (see page
49).
The programmable auxiliary contacts allow as well the
inter connection with existing systems or the implemen-
tation of extended functions. Fully programmable by
means of its remote control, it enables the update of the
software, making it an upgradeable product.

Multifunctional contacts
The potential free contacts can be programmed to provi-
de many supplementary functions.
They can react to each event, inside or outside of the
inverter (presence of the grid, battery thresholds, alarm
signal). The contacts can also be programmed as time
switch or can be disabled during sensitive periods (night,
weekend). They allow therefore the implementation of
functions like the automatic start of gensets, the auto-
matic disconnection of second priority users, the alarm
signal, the conditional charge of the battery, etc.
