636 Control of self-consumption
The control of self-consumption functions can be configured on the inverter's graphics
display. The S0 interface for the connection of the energy counter and the "Grid feed-in
limitation" operating mode for the control of self-consumption can only be configured
with MaxTalk 2 Pro.
6361 Configuring the "Pac electric meter" operating mode
The "Pac electric meter" operating mode for the control of self-consumption can be con-
figured to suit the user's requirements. The functionality is illustrated in Figure 37.

Figure 37 "Pac electric meter" operating mode
The time window of the control of self-consumption is defined by the "Start time" and
"End time" parameters. Outside this time window the control of self-consumption is
inactive.
When control of self-consumption is active, the multi-function relay closes when the
power output measured with the energy counter at the grid connection point reaches the
"Enable threshold". The consumers are then switched on. The "Enable delay" timer can
be used to delay activation. When the output power falls below the "Disable threshold",
the multi-function relay opens. The consumers are switched off.
Procedure
1. In the "Settings menu" select the "MF relay" menu.
2. In "MF relay" select the "Self-consumption" setting.
3. Under "Mode" select the "Pac electric meter" operating mode.
4. Configure the parameters:
