INSTALLER
Whatever the setting of this parameter, the maximum current of the source is respected
{1107} (Input limit).
Be careful with grid-feeding function. You must among others respect the rules in force
prescribed by your utility.
The grid-feeding with inverters connected to batteries is forbidden in some countries.
There is no ENS function (function of detection of the grid impedance) or any other
similar function linked with the grid-feeding function of the Xtender.
14.15.3 Forced grid-feeding {1524} {1525} {1526}
With the forced grid-feeding, it is possible to discharge the batteries in the grid during a given time
frame. The goal is to support a grid at during a given time of the day with stored energy. Between
the start time {1525} and the stop time {1526} the batteries are discharge to the grid-feeding voltage
target {1524}. The maximum grid-feeding current is always given by the {1523} parameter. If the start
time and the stop time are the same, then the standard grid-feeding is used and not the forced
greed-feeding (no discharge of the battery into the grid).
Per example the grid-feeding is allowed and forced between 19h00 and 20h00 at 24V. During the
day, the batteries are charged and if there is excess solar energy, it is sent to the grid to maintain the
floating voltage. At 19h00 the inverter starts to discharge the batteries in the grid at the given maximal
current. It stops to discharge at 20h.
Be careful with grid-feeding function. You must among others respect the rules in force
prescribed by your utility.
The grid-feeding with inverters connected to batteries is forbidden in some countries.
There is no ENS function or any other similar function linked with the grid-feeding
function of the Xtender. You can add an external ENS detector.
14.15.4 INSTALLER - Dephased injection {1610}
The directive VDE-AR-N 4105:2011 dictates a phase variation of the injected current in accordance
with the power. If you wish to inject a current dephased from the voltage you can use this function.
If this function is activated the injection will be made according to the parameters below.
