Q on Demand 24/7

The general setting of the grid management services (e.g. cos phi setpoint or Q(V) characteristic curve) can not be fully set independently of the "Q on Demand 24/7" function via the relevant parameters - "Q on Demand 24/7" only permits Q specifications. It is to be noted here that certain settings can have an influence on other grid-support settings and functions.

This means that if the "Q on Demand 24/7" function" is active, no other grid-supporting functions (e.g., cos phi) are possible between day and night operation of the inverter. Should an independent reactive power provision be desired between day- and night operation, the reactive power provision must be communicated to the inverter via a superordinate control unit.

The function "Q on Demand 24/7" is not compatible with the reactive power modes cos φ(P) charac. curve or cos φ(V) charac. curve.

Currently, the provision of reactive power can only be read off via the phase currents and phase voltages in the instantaneous values (Realtime values > AC Side > Phase currents / Phase voltage) or requested via Modbus.

You can set the reactive power mode using the following parameters.
