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.
Application example
Switch-on point = 2000 W, switch-off point = 1800 W
If the inverter is outputting 2000 W or above, then the floating switch contact on the inverter
is switched on.
If the inverter output falls to below 1800 W, the floating switch contact is switched off.
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
Factory setting 1000 W
Setting range Switch-off point - max. nominal output of inverter / W / kW
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
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)
