The energy supplied from the photovoltaic panels will be used:
To compensate the difference between consumed power and contracted power.
To charge the battery if there is surplus energy.
To cancel all consumption, if there is surplus energy.
If there is surplus energy and the configuration allows the energy to be injected into the
grid, it will inject it into the grid. Otherwise, the generation of photovoltaic energy will be limited.
The energy supplied by the batteries will be used:
To compensate the difference between consumed power and contracted power when there
is insufficient photovoltaic energy and the battery is not in the
“Empty battery”
state.
B�- Battery state of charge
If the
SOC
of the battery is below the
SOC Min
, the unit will be set to the
“Empty battery”
status and remain with this status until the
SOC
exceeds the
“SOC Rec”
value.
The battery cannot be charged from the electrical network in the “
Empty battery”
state. In this
case, the AC generation process will be stopped if it is detected that there is no surplus energy
in the solar panel.
Between
SOC Min
and
SOC Rec
,
CirPowerHyb
will use the energy of the solar panel to charge
the battery and, if there is surplus solar energy, the AC generation option will be activated and
used to cancel the loads. The battery can be discharged after the
SOC Rec
value is reached.
