3.3.3 Battery operation
In case of power failure or rectifier fault, the battery feeds the inverter without interruption
through the booster converter. The battery voltage drops based on the amplitude of the
discharging current. The voltage drop has no effect on the output voltage, which is kept
constant by changing the PWM modulation. An alarm is activated when the battery is near the
minimum discharge value.
In case the supply is restored before the battery is completely discharged, the system will be
switched back to normal operation automatically. In the opposite case, the inverter shuts down
and the load is switched to the bypass line (bypass operation). If the bypass line is not available
or is out of tolerance, the loads supply is interrupted as soon as the battery reaches the
discharge limit threshold (black-out).
As soon as the supply is restored, the battery charger will recharge the battery. In the standard
configuration, the loads are supplied again via static switch SSB when mains is available again.
The inverter is restarted when the battery has partially restored its capacity.
