Transitioning
from backup
power mode to
feeding energy
into the grid
1.
The inverter is operating in backup power mode. Changeover switch Q1 is in
switch position 2 (backup power mode).
2.
Public grid available again.
3.
The user switches the changeover switch Q1 from switch position 2 (backup
power mode) via switch position 0 to switch position 1 (grid operation). When
switching via switch position 0, the inverter is switched off immediately. This
is ensured via the contacts of the changeover switch Q1. To protect sensitive
loads, it is advisable to remain in the zero position for at least 1 second dur-
ing the changeover process from backup power mode to the public grid.
4.
The inverter is again connected to the entire home network and to the public
grid.
5.
Communication between the inverter and Fronius Smart Meter is re-estab-
lished.
6.
The inverter can start feeding energy into the grid again after performing the
grid checks required by the relevant standard.
