Relay test
Function test to determine whether the floating switch contact switches
Switch-on point (only if 'Energy-Manager' function is activated)
for setting the effective power limit beyond which the floating switch contact is switched on
Switch-off point (only if 'Energy-Manager' function is activated)
for setting the effective power limit beyond which the floating switch contact is switched off
Energy-Manager
(in Relay menu
item) The 'Energy-Manager' function can be used to activate the floating switch contact in such
a way that it functions as an actuator.
Thus a consumer that is connected to the floating switch contact can be controlled by spec-
ifying a switch-on or switch-off point that depends on the feed-in power.
The floating switch contact is automatically switched off,
-
if the inverter is not feeding any power into the grid,
- if the inverter is manually switched into standby mode,
- if the effective power is < 10% of nominal output,
- in the event of insufficient insolation.
To deactivate the 'Energy-Manager' function, select a different function and press the 'En-
ter' key.
Notes on setting up the switch-on and switch-off points
If the difference between the switch-on and switch-off points is too small, or if there are fluc-
tuations in effective power, the result may be multiple switching cycles.
To avoid switching on and off frequently, the difference between the switch-on and switch-
off points should be at least 100 - 200 W.
When choosing the switch-off point the power consumption of the connected consumer
should be taken into account.
When choosing the switch-on point, the weather conditions and anticipated insolation
should also be taken into account.

Further details on the 'Energy-Manager' function may be found in the
"Energy-Manager" section.
Factory setting 1000 W
Setting range Switch-off point - max. nominal output of inverter / W / kW
Factory setting 500
Setting range 0 - Switch-on point / W / kW
To activate the 'Energy-Manager' function, select 'E-Manager' and press the 'Enter' key.
When the 'Energy-Manager' function is running, the 'Energy-Manager' symbol will appear
in the top left corner of the display:
when the floating NO contact is off (open contact)
when the floating NO contact is on (closed contact)
