  • Page 179 When the Green Conversion algorithm is active the rectifier operates at reduced DC voltage and supplies the inverter alone, since the battery is disconnected from the DC bus. The battery charge is controlled by a specific algorithm. In case no mains outage events have occurred, and so no battery discharges have occurred too, the control logic provides to start a charging cycle once every 25 days.

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.
