The energy supplied from the photovoltaic panels will be used:
To charge the battery.
If the battery is at full charge, it will cancel the consumption of all direct and indirect loads.
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 battery will not be discharged while
CirPower Hyb
is connected to the AC network.
In the event of network failure, the unit will maintain the power supply of the loads at the AC
output. The supply of direct loads will depend on the state of charge of the battery (
SOC
) and
it will behave as described in the
Off-Grid
strategy (
“7.2.1.1.- Off-Grid.”
). The unit will open the
network relays, not take into account the external loads and only cancel the consumption of
energy from direct loads.
7�2�1�6�- AutoBackup
In this mode, the inverter’s priority is to cancel the loads connected to the AC output (direct
loads). In the event of a power failure, the unit will maintain the power supply of the loads at the
AC output.
The loads measured by an external analyser (indirect loads) will only be cancelled if there is a
surplus of PV power generated that cannot be absorbed by the batteries.
