Fronius Symo GEN24 10.0, Operating Instructions Manual, Page: 86 / 120

System 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, "PV1 + PV2 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 battery manufacturer's specifications.
If the SoC mode is set to "Manual", the "Minimum SoC" and "Maximum Soc" may be
changed in consultation with the battery manufacturer.
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 battery from
the public grid is enabled/disabled.
The normative or feed-in tariff rules must be taken into account with this setting. The set-
ting 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. Regard-
less 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 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 how the inverter behaves overnight. If the function is deactiv-
ated, the inverter switches to Standby mode as soon as there is no more PV power avail-
able, provided that no energy management command is sent to the battery (e.g. min-
imum state of charge reached). The message "Power low" is displayed. The inverter
restarts as soon as an energy management command is sent or there is sufficient PV
power 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 the meter is connected, the position must be configured.
Several Fronius Smart Meters can be installed in the system. 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 consumption meters.
Ohmpilot
All Ohmpilots available in the system are displayed. Select the desired Ohmpilot and add
it to the system via "Add".
Functions and
I/Os Backup power
"Off" or "PV Point" can be selected for backup power mode.
The backup power functionality can only be activated once the required I/O assignments
have been configured for backup power. The meter must be installed at the feed-in point
and configured.
