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 Set switch-off point up to the maximum nominal output
of the inverter (W or 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 to the set switch-on point of the inverter (W or kW)
Energy Manager
(under "Relay"
menu item)
The "Energy Manager" function can be used to activate the floating switch con-
tact in such a way that it functions as an actuator.
Thus, a load that is connected to the floating switch contact can be controlled by
specifying a switch-on or switch-off point that depends on the power of feeding
in.
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 to Standby mode
- If the effective power is set to < 10% of the rated power
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)
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.
