Energy Manager The "Energy Manager" (E-Manager) function can be used to activate the floating
(under Relay switch contact in such a way that it functions as an actuator.
menu item) Thus, a consumer that is connected to the floating switch contact can be con-
trolled by specifying a switch-on or switch-off point that depends on the feed-in
power (effective power).
The floating switch contact is automatically switched off:
-
-
-
GAF As soon as GAF mode is selected, the relay is switched on.
The relay opens as soon as the power stage set registers an
error and goes from normally feeding energy into the grid to
being in an error state. This means that the relay can be used
for fail-safe functions.
Application example
It may be necessary to perform phase compensation when us-
ing a single-phase inverter at a multiphase site. If an error oc-
curs on one or several inverters and the connection to the grid
is broken, the other inverters must also be disconnected to
maintain the phase balance. The "GAF" relay function can be
used in conjunction with the Datamanager or an external pro-
tection device to recognise or signal that an inverter is not
feeding in or is disconnected from the grid and to then dis-
connect the remaining inverters from the grid using a telecon-
trol command.
Active output:
ON: The floating NO contact is on all the time the inverter is in op-
eration (as long as the display is not dark or is displaying
something).
OFF: The floating NO contact is off.
Energy Manager:
E-Manager: Further details on the "Energy Manager" function may be
found in the "Energy Manager" section.
1000 W
Set switch-off point up to the maximum nominal output
of the inverter (W or kW)
500
0 to the set switch-on point of the inverter (W or kW)
If the inverter is not feeding any power into the grid
If the inverter is manually switched to Standby mode
If the effective power is set to < 10% of the nominal output of the inverter.
