Self-consumption control function 1
Control of self-consumption by time
When a certain rating P1 has been generated for a
certain period of time T1, the inverter switches to
self-consumption.
The inverter remains in self-consumption mode for the
entire run time T2. Following the run time T2, the inverter
ends self-consumption.
This is the end of the interval. This interval can be
repeated several times with the "Activation" option.

INFO
If there is a battery connected to the
inverter, when charging the battery,
this energy is drawn from the gener-
ated PV energy. When this happens,
instances may arise where the thresh-
old value P1 is not reached despite
sucient PV energy.
When selecting "Dynamic self-con-
sumption control", the measured
home consumption Pc (e.g. 700W in
this case) is taken into consideration
and automatically added to the set
power limit P1. In our example, this
means that the contact only closes at
1700W.
INFO
If the “Permit battery usage for the
switched output” option is also acti-
vated, the missing amount of energy
is drawn from the battery should the
PV energy drop.
