CHECKLIST - BACKUP POWER

Once installation, conguration, and commissioning have been successfully completed, this checklist must be worked through to ensure the back­up power changeover function and backup power mode are operating correctly.

TASK TEST CONFIRMATION

The inverter, battery, and all other necessary compo­nents have been installed and assembled correctly.

The backup power changeover unit has been installed
and commissioned in accordance with the country-spe­cic installation guidelines and as outlined in the docu­mentation.

The software settings have been carried out in accor-

dance with the „Backup power conguration“ chapter in

the documentation.

A warning notice has been put on the switch cabinet to
warn that a backup power supply has been installed.

Start the inverter in grid power feed operation. Check whether the inverter starts in grid power feed

Disconnect the PV system from the public grid. This

can be e󰀨ected using a disconnecting device in the

upstream AC path or the disconnecting devices (e.g. NH
fuse) of the building connection. The disconnection must
occur before the Smart Meter (grid side).

Measure the voltage/frequency in the established stand­alone operation.

Reconnect the PV system to the public grid. The time taken from the end of stand-alone operation

operation and a power shift takes place. (Test duration
6 minutes).

Check whether the inverter starts in stand-alone opera­tion. The changeover can take more than 1 minute.

Set value: 230 V / ± 10 % / 53 Hz
USA: 120 V / ± 10 % / 63 Hz

until the subsequent connection of the contactors in
the backup power changeover unit must be at least 10
seconds. The changeover can take more than 1 minute.

Only then may the inverter resume grid power feed
operation. This must be checked by the inverter (test
duration 6 minutes).

I hereby conrm that the backup power changeover function and backup power mode are operating correctly.
