72 V4.4.0 User manual
14.14.1 3-phase integral mode {1283}
If you activate this parameter, the system will work in order to have either a 3-phase output, or no
output voltage. For instance in case of one phase overload, if the integral mode is activated, the cut
of this phase will lead to the cut of all phases.
14.14.2 Multiple authorized inverters {1461}
This parameter allows to forbid the setting in parallel or in 3-phase of a system. If this parameter is
deactivated and several Xtender are connected with the link cable, it will be impossible to put them
on.
14.14.3 Multiple independent inverters {1462}
This setting allows you to use several Xtenders connected via the same communication bus, without
using synchronization. The phase selection tabs are therefore not in operation. However, in order to
display the user information, the RCC remote control uses this information (if two inverters are
programmed on the same phase, they appear as if they are in parallel on the remote control).
14.14.4 Battery cycle synchronized by the master {1555}
When several inverters are connected to the same battery, it is preferable that they all have a battery
cycle synchronized, to carry out for instance an equalizing at the same time. When this parameter is
activated, the inverter master of the system imposes the ongoing battery cycle to the others.
If several separated batteries are used, this parameter must be put on NO.
14.14.5 Authorize the stand-by of the secondary inverters (slaves) {1547}
When several Xtenders are connected in parallel and the energy consumption is reduced, one single
Xtender may be enough to cope with the needs. In that case, the others can be put in stand-by in
order to save energy. This parameter allows you to authorize or not the stand-by of the secondary
Xtenders.
As soon as the power reaches around 75% of the Xtender nominal power the others are
activated.
The activation time is around 50ms.
14.14.6 Splitphase: L2 with 180 degrees phase displacement {1571}
Displaces the phase L2 by 180 degrees instead of standard threephase systems 120 degrees. L2 is in
reverse phase compared to L1.
This is about an electrical configuration mainly used in North and Central America. It is
meant to obtain 240V with two inverters in reverse phase, while keeking 120V on each
phase.
14.14.7 INSTALLER – Compatible Minigrid {1437}
This parameter makes your inverter suitable to be integrated into a minigrid distributed system. For
more information on minigrids, contact us on info@studer-innotec.com.
14.14.8 INSTALLER – Minigrid with battery energy sharing {1577}
In a minigrid system, this parameter authorizes or not the inverter to share its energy with the rest of
the system. For more information on minigrids, contact us on info@studer-innotec.com.
