Load

The mains is not within the required tolerance range or has failed. In this case, power is supplied to the inverter from the charged battery without interruption. The power supply to the loads is therefore also ensured in the event of a mains failure. This drains the capacity of the battery and it is discharged. This status is signalled by the battery symbol lighting up (Battery LED), as well as an intermittent acoustic signal, at first every 4 seconds and then every second shortly before switching off. The initial alarm can be suppressed by pressing the “Alarm off” button. The alarm is automatically reactivated when the battery capacity decreases. Depending on the expansion level, age and condition of the battery and in particular on the load to be supplied, the standby time can vary from a few minutes to several hours.

The inverter is switched off if the battery voltage drops below a factory-set minimum voltage value.

Never store the unit in this condition! The discharged battery system should be recharged within a week at the latest.

When the voltage and frequency are within the tolerance range again after the mains is restored, the rectifiers switch back on
