Settings – System overview
System overview
PV generator
If there is no solar module connected to the Fronius hybrid inverter, the PV
power option must be deactivated. The connected PV power must be entered in
the field underneath.
Battery
If a battery is connected to the Fronius hybrid inverter, it must be activated here.
This setting can only be made when there is an active connection to a battery. If
you are unable to make this setting, check whether the battery is switched on
and whether the data connection has actually been established.
If there is a connection, the current state of charge of the battery will be indic-
ated underneath the battery symbol.
Enabling battery charging from DNO grid
If you want the battery to be charged from the public grid, you can activate this
here. Depending on what is required by standards or the feed-in tariff rules, it
may be necessary to deactivate the setting.
This setting does not affect the charging of the battery by other producers within
the home. It merely relates to the process of drawing charging energy from the
public grid.
Regardless of this setting, the battery will still be charged from the public grid if
needed for service reasons (e.g. to protect against deep discharge)
Fronius Checkbox 500V installed
If a battery from the LG Chem ResuH series is connected, a Fronius Checkbox
500V must be installed and this option must be activated.
Emergency power
Emergency power mode can be activated or deactivated here. The emergency
power functionality can only be activated once the required IO assignments have
been configured for emergency power. The meter must be installed at the feed-in
point and configured.
External producer
If further decentralised producers are installed in the household and have been
integrated into the self-consumption rule for the Fronius hybrid inverter, you
must activate this setting. This means that energy can be drawn from the house-
hold network and fed into the battery via the Fronius hybrid inverter.
You can restrict how much power is consumed by the Fronius hybrid inverter by
specifying a maximum AC power value (AC max.). The maximum power consump-
tion is limited to the AC nominal output of the Fronius hybrid inverter.
Meter
To ensure smooth operation in conjunction with other energy producers and in
emergency power mode, it is important to install the Fronius Smart Meter at the
feed-in point. The Fronius hybrid inverter and other producers must be connec-
ted to the public grid via the Fronius Smart Meter.
This setting also affects how the Fronius hybrid inverter behaves overnight. If the
function is deactivated, the inverter switches to Standby mode as soon as there
is no more PV power available, provided that no energy management command is
sent to the battery (e.g. minimum state of charge reached). The message "Power
