Energy Manager The "Energy Manager" function can be used to activate the floating switch contact in
(under Relay such a way that it functions as an actuator.
menu item) Thus, a consumer that is connected to the floating switch contact can be controlled by
specifying a switch-on or switch-off point that depends on the feed-in power.
The floating switch contact is automatically switched off:

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:
To deactivate the "Energy Manager" function, select a different function and press the
"Enter" key.
Notes on setting up the switch-on and switch-off points
The interface of the energy management relay always uses the output power of the
inverter as a reference point, although this will not necessarily match what is generated
by the PV system in the case of the hybrid system.
If the difference between the switch-on and switch-off points is too small, or if there are
fluctuations in effective power, the result may be multiple switching cycles
To avoid frequent switching on and off, 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.
1000 W
Set switch-off point up to the maximum nominal output of the
inverter (W or kW)

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
