Device configuration
Components Select "Add co" to add all available components to the system.
PV generator
Activate the MPP tracker and enter the connected PV power in the associated
field. For combined solar module strings, "PV 1 + PV 2 connected in parallel"
must be activated.
Battery
If the SoC mode is set to "Automatic", the values "Minimum SoC" and "Maximum
SoC" are preset according to the technical specifications of the battery manu-
facturer.
If the SoC mode is set to "Manual", the values "Minimum SoC" and "Maximum
SoC" may be changed after consultation with the battery manufacturer within
the scope of their technical specifications. In the event of a power outage, the
set values are not taken into account.
Using the "Allow battery charging from additional producers in home network"
setting, charging of the battery from other external producers is enabled/
disabled.
Using the "Allow battery charging from public grid" setting, charging of the bat-
tery from the public grid is enabled/disabled.
The normative or feed-in tariff rules must be taken into account with this setting.
The 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, any charging from the public grid that is
required for service reasons (e.g. necessary re-charging to protect against deep
discharge) is still performed.
IMPORTANT!
Fronius accepts no liability for damage to third-party batteries.
Primary meter
To ensure smooth operation in conjunction with other energy producers and in
Full Backup backup power mode, it is important to install the Fronius Smart
Meter at the feed-in point. The inverter and other producers must be connected
to the public grid via the Fronius Smart Meter.
This setting also affects the behaviour of the inverter at night. 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 low" is
displayed. The inverter restarts as soon as an energy management command is
sent or sufficient PV power is available.
If the function is activated, the inverter remains permanently connected to the
grid so that energy can be drawn from other producers at any time.
After connecting the meter, the position must be configured. A different Modbus
address needs to be set for each Smart Meter.
The Watt value on the generator meter is the sum of all generator meters. The
Watt value on the consumption meter is the value of all secondary meters.
Ohmpilot
All Ohmpilots available in the system are displayed. Select the desired Ohmpilot
and add it to the system via "Add".
