If you use this parameter with parameter {1549}, you will have the two corrections
stacked over one another.
The main application of this parameter is the automatic control of a grid inverter
connected to the Xtender output.
When the batteries are not fully charged, the grid inverter charges them through the
Xtender.
Once the batteries are charged, the Xtender modifies the output frequency and the
grid inverter stops automatically.
The grid inverter must be compatible with this solution (grid feeding cut if the frequency
is too high).
If the grid inverter does not cut it may lead to a batteries overload and their definitive
damaging.
The grid inverter power must not exceed either the Xtender nominal power or the
maximum power charge of the batteries; otherwise it will lead to irreversible damages
to them.
14.9.7 Frequency increase with the battery voltage {1549}
If you activate this parameter, the output
frequency in inverter mode will vary in
proportion to the battery voltage. The function
is depending on the batteries charge cycle
and uses the reference voltage of the current
cycle.
The basic frequency is increased up to the
maximum value of parameter {1546}.
A : Maximum increase of the frequency {1546}
B : Battery cycle voltage reference
C : 0.5V for 12V
1V for 24V
2V for 48V
For instance if the battery carries out an absorption, the output frequency will be modified around
this setting value. If the battery is in floating phase, the output frequency will be modified around this
setting value.
If you use this parameter with parameter {1536}, you will have the two corrections
stacked over one another.
14.9.8 Maximum increase of the frequency {1546}
This parameter determines how much the basic frequency is increased when a frequency variation
is wished.
