8 Decommissioning
8.1 Disconnecting the Off-Grid Inverter from Voltage Sources
1. Disconnect the off-grid system (see the operating manual of the off-grid inverter).
2. Open the switch-disconnector of the BatFuse and secure it against reconnection (see the manual
of the BatFuse).
3. Disconnect the miniature circuit-breakers and fuse-switch-disconnectors in the sub-distributions
and secure them against reconnection.
5. Unscrew all screws of the enclosure lid and remove the enclosure lid.
6. Ensure that the DC connection is disconnected from voltage sources.
7. Ensure that the terminals AC1 Loads/SunnyBoys and AC2 Gen/Grid are disconnected from
voltage sources.
8. Earth and short-circuit the AC conductors.
9. Cover or safeguard any adjacent live components.
8.2 Disassembling the Off-Grid Inverter
1. Disconnect the off-grid inverter from voltage sources (see Section 8.1).
2. Remove all cables from the off-grid inverter.
3. Close the off-grid inverter (see Section 7.3).
4. Remove the ventilation grids sideways.
