56 V4.4.0 User manual
14.9.10.4 Duration of Softstart {1599}
Once the inverter is switched on the output voltage is progressively raised. This parameter sets the
duration that is necessary to reach the nominal voltage.
14.9.11 Solsafe presence, energy source at AC-Out side {1438}
This parameter allows the connection on the AC-Out side of an inverter for grid feeding. It also
authorizes the Xtender to accept the energy coming from the output and to use it to charge the
batteries.
14.10 AC-IN AND TRANSFER {1197}
These configurations manage the combined
functions between the charger and inverter.
The conditions for passing from one function
to another are adjusted in this category.
A. Stoppage of charger operation {1309}
B. Disconnection of transfer subject to
delay {1199}
C. Delay before opening of the transfer
{1198}
D. Immediate passage to the inverter
threshold {1200}
14.10.1 Authorized transfer {1128}
The transfer relay is authorized or not. If the transfer is not authorized, a correct voltage at the AC-In
input will not be transferred to the output and to the users. The battery charger function is not possible
and the Xtender operates only in inverter mode.
Where there is lock on the inverter, charger or transfer
function, a small padlock is displayed on the
configuration display.
14.10.2 Delay before closing of the transfer relay {1580}
This parameter enables to delay the closing of the transfer relay even if the AC-In voltage is present.
This function can be useful while working with gensets having a pre-warming delay.
14.10.3 Smart-Boost authorized {1126}
The function Smart-Boost enables to add the power from the batteries to the one supplied by source
connected to the AC-In when the user load is higher than that, set by the parameter {1107}, as a
maximum input. This function is active by default.
When the Smart-Boost function is active, the batteries can be discharged even if a
source is present at the input of the Xtender and the charger is active.
14.10.4 Limitation of the Smart-boost power {1607}
This function limits the power that the smart-boost function provides the backup source. The entered
value represents the maximal power delivered in regards to the inverter's P30 power.
