be held liable for any damage arising from such usage.
For exact information on permitted environmental conditions, please refer to
the "Technical data" in the operating instructions.
9
Qualified service
engineers
The servicing information contained in these Operating Instructions is intended only for the use of qualified service engineers. An electric shock can be fatal. Do not perform any actions other than those described in the
documentation. This applies even if you are qualified to do so.
All cables and leads must be secured, undamaged, insulated and adequately
dimensioned. Loose connections, scorched, damaged or inadequately dimensioned cables and leads must be immediately repaired by authorised personnel.
Maintenance and repair work must only be carried out by authorised personnel.
It is impossible to guarantee that bought-in parts are designed and manufactured to meet the demands made of them, or that they satisfy safety requirements. Use only original spare parts (also applies to standard parts).
Do not carry out any modifications, alterations, etc. to the device without the
manufacturer's consent.
Components that are not in perfect condition must be replaced immediately.
Noise emission
values
The maximum sound power level of the inverter is specified in the Technical
Data.
The device is cooled as quietly as possible with the aid of an electronic temperature control system; this depends on the amount of converted power, the
ambient temperature, the level of soiling of the device, etc.
It is not possible to provide a workplace-related emission value for this device
because the actual sound pressure level is heavily influenced by the installation situation, the power quality, the surrounding walls and the properties of
the room in general.
EMC measures
In certain cases, even though a device complies with the standard limit values
for emissions, it may affect the application area for which it was designed (e.g.
when there is sensitive equipment at the same location, or if the site where the
device is installed is close to either radio or television receivers). If this is the
case, then the operator is obliged to take appropriate action to rectify the situation.
Emergency power
This system is equipped with an emergency power function. This means a
backup power supply is automatically established in the event of a power outage.
EMERGENCY POWER
NOTSTROM
For maintenance and installation work, the system must both be isolated from the grid, and
backup power mode must be disabled by opening the integrated DC disconnector on the
inverter.
10
Disposal
To comply with the European Directive 2002/96/EC on Waste Electrical and
Electronic Equipment and its implementation as national law, electrical equipment that has reached the end of its life and dead batteries must be sorted
from general waste and returned to an approved recycling facility. Any device
that you no longer require must either be returned to your dealer or given to
one of the approved collection and recycling facilities in your area. Ignoring
this European Directive may be harmful to the environment and your own
health!
If you need to replace your battery at some point, Fronius will take back the
old device and arrange for it to be recycled in an appropriate manner.
Copyright
Copyright of these operating instructions remains with the manufacturer.
The text and illustrations are all technically correct at the time of printing. We
reserve the right to make changes. The contents of the operating instructions
shall not provide the basis for any claims whatsoever on the part of the purchaser. If you have any suggestions for improvement, or can point out any
mistakes that you have found in the instructions, we will be most grateful for
your comments.
Data protection
The user is responsible for the safekeeping of any changes made to the factory settings. The manufacturer accepts no liability for any deleted personal
settings.
11
EN
The emergency power supply is automatically activated and deactivated depending on the
insolation conditions and the state of charge of the battery. This means that emergency
power can be re-established unexpectedly when in standby mode. For this reason, when
the emergency power supply is deactivated, switch off all connected devices and do not
undertake any installation work on the household network.

The hybrid inverter converts the direct current generated by the solar modules into alternating current. This alternating current is fed into the public grid synchronously with the grid
voltage. In addition, the solar energy can be stored in a connected Fronius Solar Battery
for later use.
The hybrid inverter has been developed specifically for use in grid-connected photovoltaic
systems. Emergency power mode is possible provided that appropriate wiring has been
installed.
Thanks to its design and operating principle, the inverter is extremely safe both to install
and to operate.
The inverter monitors the public grid automatically. In the event of abnormal grid conditions, the inverter ceases operating immediately and stops feeding power into the grid (e.g.
if the grid is switched off, if there is an interruption, etc.).
Grid monitoring involves voltage, frequency and islanding detection monitoring. The inverter switches to emergency power mode provided that appropriate wiring has been installed.
Operation of the inverter is fully automatic.
The inverter is designed to draw as much power from the solar modules as possible.
Depending on the operating point, this power is either stored in the battery, fed into the grid
or used for the household network in emergency power mode.
As soon as the solar modules stop providing sufficient energy, the power from the Fronius
Solar Battery is fed into the household network. Depending on the selected setting, power
can also be drawn from the public grid for the purpose of charging the battery.
If the inverter becomes too hot, it automatically reduces the current output power or charging power, or switches to emergency power mode in order to protect itself.
Reasons for the inverter becoming too hot include the ambient temperature being too high
or inadequate heat dissipation (e.g. if it is installed in a switch cabinet without suitable heat
dissipation).
IMPORTANT! The Fronius Solar Battery is only to be switched on when the inverter is in
Standby mode.
15
Proper use
The solar inverter is exclusively intended for charging a Fronius Solar Battery with direct
current from solar modules, or for converting this direct current into alternating current and
feeding it into the public grid or the household network in emergency power mode.
The following actions constitute improper use:
Any use above and beyond this purpose
Making any modifications to the inverter that have not been expressly approved by
Fronius
Installing components that are not distributed or expressly approved by Fronius
Operating the device with a battery that has not been approved by Fronius
Operating the equipment with an energy meter that has not been approved by Fronius
Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.
Proper use also includes:
Carefully studying and obeying the installation and operating instructions
performing all stipulated inspection and maintenance work
When designing the photovoltaic system, ensure that all of its components are operated
within their permitted operating ranges at all times.
Observe all the measures recommended by the solar module manufacturer to ensure that
the solar module retains its properties in the long term.
Observe the stipulations of the power supply company concerning energy fed into the grid,
emergency power mode and the operation of storage systems.
The Fronius Symo Hybrid is a grid-connected inverter with an emergency power function
– it is not a stand-alone inverter. The following restrictions must therefore be observed in
emergency power mode:
Emergency power mode may amount to max. 15% of the normal inverter operating
time
Emergency power mode must be in operation for (at least) 1500 hours
Warning notices
on the device
There are warning notices and safety symbols on and in the inverter. These warning notices and safety symbols must not be removed or painted over. They warn against incorrect

With the market launch of its new Fronius Energy Package, Fronius is introducing an inverter that can be used to store energy. One of the key components is the Fronius Solar
Battery, which contains a lithium-ion rechargeable cell. The Fronius Solar Battery supplements the Fronius hybrid inverter by adding storage functionality. This means that the solar
energy from the solar modules can be stored for later use.
The storage system is only suitable for operation in conjunction with Fronius hybrid inverters.
Thanks to its design and operating principle, the storage system is extremely safe both to
install and to operate. A high-performance lithium-ion phosphate battery is used
(LiFePO4), which is based on the latest technology and complies with the highest safety
standards.
When used in conjunction with the Fronius inverter, operation of the storage system is fully
automatic.
If proper charging of the batteries in the Fronius Energy Package cannot be guaranteed for
an extended period of time (over several weeks or months) for any reason, we strongly recommend that the following steps are undertaken to prevent the deep discharge of the battery modules:
switch off the main switch of the Fronius Solar Battery
remove the DC fuses from the fuse holder
remove the orange power connector from the individual battery modules
Proper use

Operating mode:
Inverter plus battery
To ensure fault-free regulation, parallel operation of several Fronius Energy Packages is
not permitted.
To maximise self-consumption of the energy provided by your PV system, you can use a
Fronius Solar Battery to act as a storage system. The Fronius Solar Battery is connected
to the inverter on the DC side. As a result, there is no need for multiple current conversion
processes, leading to greater efficiency.

IMPORTANT! In emergency power mode, an increased nominal frequency is used in order to avoid parallel operation with other generators.
To ensure fault-free regulation, parallel operation of several Fronius Energy Packages is
not permitted.
Operating statuses (only for systems with a
battery)
The Fronius Energy Package differentiates between various operating statuses. The current operating status is displayed on the system monitoring website or in Solar.web
Operating status
Description
Deactivated
The battery is not active. It has either been deactivated,
or no communication with the battery or meter is possible
due to a fault.
Normal operation
The system is in normal operation
Service mode
Service mode has been activated. The battery is automatically charged or discharged to a defined SOC value
and then kept at this value until service mode is ended
manually.
Forced re-charging
The Fronius Symo Hybrid recharges the battery to counteract self discharge and maintain the set minimum SOC
(protection against deep discharge).
Min. SOC reached
The battery has reached the set minimum SOC. The battery cannot be discharged further until it has been
charged again.
Energy saving mode
The system has been set to energy saving mode. All
LEDs and the battery display do not light up. The inverter
display also does not light up. Energy saving mode ends
automatically when sufficient excess energy is available.
Calibration mode
The system is in calibration mode. When there is insufficient PV energy available to reach 100%, the battery is
cyclically charged to 100% for internal calibration. Under
certain conditions (depending on weather, microcycles,
temperature, etc.), this can take an extended period of
time (up to several days).

Restrictions in
emergency power
mode
The public grid is monitored by the inverter's internal grid and system protection and
by the Fronius Smart Meter connected to it.
The public grid fails or specific grid parameters are not reached or exceeded.
The inverter carries out the measures necessary according to the country standard
and then switches off.
The inverter starts emergency power mode after a checking period.
All consumers in the household that are in the emergency power circuit are supplied
by the Fronius Solar Battery and the solar modules. The remaining consumers are not
supplied with power and are safely isolated.
The inverter is operating in emergency power mode.
The public grid is functioning correctly again.
The Fronius Smart Meter monitors the grid parameters on the public grid and passes
this information to the inverter.
After a defined measuring period, the restored public grid is deemed to be stable.
The inverter ends emergency power mode.
All circuits are reconnected to the public grid and are supplied by the grid.
The inverter can start feeding energy into the grid again after performing the grid
checks required by the country standard.
In emergency power mode, some electrical appliances cannot function properly as starting
currents are too high (e.g. fridges and freezers). It is recommended to switch off non-essential consumers during emergency power mode.
Switching from grid-connected operation to emergency power mode takes a little while. For
this reason, the Fronius Energy Package with emergency power function cannot be used
as an uninterruptible power supply, for example for computers.
If no energy is available from the Fronius Solar Battery or the solar modules during emergency power mode, this mode is automatically ended, regardless of whether the public grid
is available or not. If sufficient energy becomes available from the solar modules once
again, emergency power mode starts again automatically.
25
If consumption is too high, emergency power mode is interrupted and status code "143 Emergency power overload" appears. The maximum power in emergency power mode according to the technical data must be observed!
Emergency power and energy
saving mode
If the inverter is operating in emergency power mode, energy saving mode is automatically
active. Under the following conditions, the battery and the inverter are switched to energy
saving mode after a waiting time of 12 minutes:
The battery is discharged to the minimum state of charge and no energy is coming
from the solar modules
The inverter is in an error state that is not acknowledged automatically (e.g. multiple
overload)
The inverter is set to energy saving mode (standby mode) using the display setting.
If the battery and inverter are in energy saving mode, the system is reactivated by the following:
Enough energy is available from the solar modules
The public grid is functioning again
The battery's POWER switch is switched off and on
More information on energy saving mode can be found in chapter Energy saving mode on
page 27

Energy saving mode
General remarks
Energy saving mode (standby) is used to reduce the self-consumption of the system. It is
available from version 1.4.1-11 of the system monitoring software. Both the inverter and
the battery switch to energy saving mode automatically under certain conditions.
Fronius Symo Hybrid
If the battery is empty and no PV energy is available, the inverter switches to energy saving
mode. Only the inverter's communication with the Smart Meter and Solar.web is maintained.
Fronius Solar Battery
When the battery is in energy saving mode, the display remains dark. In Solar.web, energy
saving mode is indicated by an "i" next to the battery symbol. In the energy balance view,
the SOC (State of Charge) of the Fronius Solar Battery is not displayed for the duration of
energy saving mode.
Fronius Solar
Battery and Fronius Symo Hybrid
switch-off conditions
The state of charge of the battery is lower or the same as the minimum
< min. SoC state of charge entered.
The output of the solar modules is less than 50 W.
< 50 W
The current charge or discharge power of the battery is less than 100 W.
< 100 W
Less than 50 W is available to charge the battery. The power of feeding
< 50 W into the public grid is at least 50 W lower than the power currently required
in the household network.
If all switch-off conditions are met, the battery switches to energy saving mode within 6 minutes. This time delay ensures than the inverter can at least be restarted.
The inverter automatically switches to energy saving mode after the battery.
Emergency power:
If the emergency power function has been activated, the battery in grid operation does not
switch to energy saving mode. Otherwise, the black start (start without grid and PV supply)
of the hybrid system could not be ensured.
During emergency power operation and when the state of charge falls below the minimum,
the battery switches to energy saving mode.
Fronius Symo Hybrid and Fronius
Solar Battery
switch-on conditions
If one of the following conditions is met for at least 30 seconds, energy saving mode is ended:
Energy saving mode is no longer permissible due to changed settings on the inverter
website.
More than 50 W is available to charge the battery. The power of feeding into the public
grid is at least 50 W higher than the power currently required in the household network.
If the dynamic power reduction is set to 0 or if the system is operating in emergency
power mode, the power of feeding into the public grid is always lower than the power
required in the household network.
In this case there is a separate condition (dynamic power reduction < 300 W or emer-
27
gency power mode active). If the PV power is above a set threshold (50 W), energy
saving mode is ended.
Special case
If the inverter has not been operational for 12 minutes (e.g. in the case of a fault), the battery switches to energy saving mode. This prevents the self discharge of the battery.
Indicators on the
displays and user
interfaces
During energy saving mode:
the battery display is dark
the inverter display is dark
the inverter website can be accessed
all available data is saved and sent to Solar.web
the current available data can be viewed on Solar.web
Energy saving mode is shown on the inverter website and in Solar.web by an "i" next to the
battery symbol in the system overview.

Calibration charging
General remarks
Determining the exact state of charge (SOC) of the Fronius Solar Battery is important for
operation. To ensure this happens, the battery must regularly be charged to 100%. This
allows the SOC value to be calibrated.
Calibration charging occurs automatically during operation after several charge and discharge cycles. When calibration charging is carried out depends on two crucial factors:
Average state of charge
Energy throughput of the battery
As these factors are extremely weather dependent, the time of a calibration charge can
vary depending on the time of year. The following description of calibration charging is valid
from version v1.4.1-12 of the Fronius system monitoring software.
Benefits of calibration charging
Natural differences in the individual cell capacities and the small amount of self discharge
that occurs in all batteries cause the cell voltages to diverge. This makes the SOC value
less precise, which has an influence on operation. If no steps are taken, the battery may
become damaged.
The cyclic calibration charging brings all cells in the battery to the same state of charge and
calibrates the SOC value. This ensures a long service life of the battery cells.
Conditions for the
start of calibration charging
One charge and discharge cycle corresponds to an energy throughput of 48 Ah per battery
module. Calibration charging occurs cyclically according to the following conditions:
After 3 full charge and discharge cycles and a SOC of 80%
After 5 full charge and discharge cycles and a SOC of 50%
After 7 full charge and discharge cycles, independent of the SOC
For newly installed systems and for module replacement or expansion, a calibration charge
is started automatically after 30 minutes.
Calibration charging procedure
Calibration charging primarily occurs with the entire PV power. If insufficient PV energy is
available, energy is drawn from the public grid. This is also the case even if the "Battery
charging from DNO grid" function is deactivated, as this is a critical requirement.
The SOC is calculated per battery module. For this reason, each battery module must
reach a SOC of 100%.
Calibration process

2.
The start conditions must be fulfilled
The battery is charged to 100% with a minimum current of 6.5 A or the total PV power.
29
3.
4.
5.
6.
Duration of calibration charging
So that a SOC of 100% can be reached for each battery module, one of the following
two conditions must be fulfilled for at least 2 minutes (for each cell in every battery
module):
– Minimum cell voltage  3.45 V and current < 100 mA
– Minimum cell voltage > 3.5 V independent of current
When a battery module reaches one of these conditions, the current is limited to prevent an overload. A current in the two-digit mA range flows over a bypass resistor
Unneeded PV power is reused directly
Once all cells in all battery modules have fulfilled one of the two conditions, the SOC
is set to 100% and calibration charging is complete.
Due to tolerances in the cells, they are not always charged and discharged at the same
rate. As cells and battery modules are connected in series and the slowest cell determines
the charging and discharging duration, some calibration charges need more or less time.
In rare cases, calibration charges or full charge cycles (depending on the time of year, e.g.
in the winter months) can lead to large variations in the cell voltages in the battery modules.
In calibration mode, one cell charges more quickly than the others. This cell then begins
redistribution. The other cells can then only be charged with a reduced charging current. It
takes longer for these cells to reach the target value.
If the battery is regularly charged completely, calibration charges are rarely required. The
cells are calibrated during every charge with 100% SOC.
In the winter months. where there are few full charges and a lower energy throughput, calibration charges can take longer, as higher variations between the battery modules must
be redistributed.
Limitations during calibration
-
Display during
calibration charging
Drawing energy from the battery (discharging) is not possible
Self-consumption optimisation is disabled while calibration charging is in progress
Charging from the grid can still occur if the "Battery charging from DNO grid" function
is not activated, as this process concerns system-relevant service charging
Zero feed-in continues according to the standard and service charging can even be
started if you wish to expand or replace battery modules during calibration
Emergency power mode can be started – calibration charging is interrupted
As soon as calibration charging starts, it becomes visible in Fronius Solar.web (current and
energy balance view) or on the web interface of the Fronius Symo Hybrid inverter.
In Fronius Solar.web or on the web interface of the inverter, the calibration
charge information is displayed in the overview. Clicking on the battery
symbol (see the image on the left) displays the information „The battery is
in calibration mode“.
In the energy balance display in Solar.web, both the start and end of the calibration charge
is displayed by changing the battery status ("Batterie Modus: Normal Calibrate" and
"Batterie Modus: Calibrate Normal")
The following graphic shows calibration charging in the energy balance view. At the start
of calibration charging, the total PV production is used to charge the battery. From the point
where one cell is fully charged, only a certain charging current is drawn by the battery. This
charging current decreases towards 0 A as the cell voltage increases.
30
EN
As during normal operation, the status "charging" (CHG) is shown on the battery display
and the relevant charging current in ampere is displayed. If the charging current drops to
below 0.3 A, 0 A is shown on the display, even though calibration charging continues.
In Fronius Solar.web, the SOC value for the entire battery is displayed. On the battery display, the SOC values of the individual battery modules can be viewed.

The “Energy Manager” function can be used to activate the floating switch contact in such
a way that it functions as an actuator.
Thus, a consumer that is connected to the floating switch contact can be controlled by
specifying a switch-on or switch-off point that depends on the feed-in power.
The floating switch contact is automatically switched off:
If the inverter is not feeding any power into the grid
If the inverter is manually switched to Standby mode
If the effective power is set to < 10% of the nominal output
To activate the “Energy Manager” function, select “E-Manager” and press the “Enter” key.
When the “Energy Manager” function is running, the “Energy Manager” symbol will appear in the top left corner of the display:
When the floating NO contact is off (open contact)
When the floating NO contact is on (closed contact)
To deactivate the “Energy Manager” function, select a different function and press the “Enter” key.
Notes on setting up the switch-on and switch-off points
The interface of the energy management relay always uses the output power of the inverter
as a reference point, although this will not necessarily match what is generated by the PV
system in the case of the hybrid system.
If the difference between the switch-on and switch-off points is too small, or if there are fluctuations in effective power, the result may be multiple switching cycles
To avoid frequent switching on and off, the difference between the switch-on and switchoff points should be at least 100 - 200 W.
When choosing the switch-off point, the power consumption of the connected consumer
should be taken into account.
When choosing the switch-on point, the weather conditions and anticipated insolation
should also be taken into account.
50
If the inverter is outputting 2000 W or above, then the floating switch contact on the inverter
is switched on.
If the inverter output falls to below 1800 W, the floating switch contact is switched off.

Fronius system monitoring
EN
General
General remarks
The Fronius system monitoring feature is a networked datalogger that manages to combine the functions of the Fronius Com Card, the Fronius Datalogger Web, the Fronius Power Control Card and the Fronius Modbus Card on a single plug-in card.
The Fronius system monitoring web page offers a rapid overview of the photovoltaic system.
It can be accessed via a web browser when there is a direct connection or – if configured
to support an indirect connection – over the Internet.
Fronius system monitoring is easy to configure and provides automatic alerts. Alerts can
be sent via SMS or e-mail.
If the feature is used in conjunction with Fronius Solar.web, current data and archive data
can be accessed for a particular photovoltaic system via the Internet or the Fronius Solar.web App without the need for any laborious configuration work. Fronius system monitoring automatically sends the data to Fronius Solar.web.
Prerequisites for
operation
So that data can be exchanged smoothly over the Internet, you must have a suitable Internet connection:
For wired Internet solutions, Fronius recommends a download speed of at least 512
kbit/s and a minimum upload speed of
256 kbit/s.
For solutions that rely on mobile Internet services, Fronius recommends 3G transmission as a minimum, plus a reliable signal.
Even if these specifications are adhered to, there is still no guarantee that everything will
run smoothly.
High error rates during transmission, variable reception conditions or transmission dropouts can all have a detrimental effect on the online functionality of Fronius system monitoring.
Fronius recommends testing any connections that meet the minimum requirements locally.
65
Calculating data volumes
General
When using Fronius system monitoring, data is collated that must be transmitted over the
internet.
The data volume must be calculated so that the correct internet connection is selected.
The data volume calculation below provides an overview of the data quantities involved
when using Fronius system monitoring.
Calculating data

The data volume calculation depends on the number of connected devices in the system
monitoring.

Data volume per month:
A data volume of approx. 500 kB per hour is required to view the system on Fronius Solar.web or the Fronius Solar.web App.
A certain data volume is also required to update the Fronius system monitoring firmware.
This data volume depends on the size of the update package and therefore cannot be considered in the advance data volume calculation.
If data is sent via a third-party service (e.g. push service), a large quantity of data may be
involved.
IMPORTANT! Fronius recommends a flat rate data connection to avoid high connection
charges.

General information for the network administrator
Prerequisites
NOTE! Knowledge of networking systems is required in order to configure Fronius system monitoring for the network.
If you are integrating Fronius system monitoring into an existing network, you must adapt
the address settings in line with the network.
For example: Network address space = 192.168.1.x, subnet mask = 255.255.255.0
-
An IP address of between 192.168.1.1 and 192.168.1.254 must be assigned to Fronius system monitoring.
The selected IP address must not be in use on the network already.
The subnet mask must match that of the existing network (e.g. 255.255.255.0).
If you want Fronius system monitoring to send service messages or to transmit data to Fronius Solar.web, you must enter a gateway address and a DNS server address. Fronius
system monitoring uses the gateway address for the purpose of establishing an Internet
connection. An example of a suitable gateway address would be the IP address of the DSL
router.
IMPORTANT!
Fronius system monitoring must never be assigned the same IP address as the PC/
laptop itself!
Fronius system monitoring is not capable of connecting to the Internet on its own. In
the case of a DSL connection, a router has to establish the Internet connection.
General firewall
settings
In order to be able to perform the various functions offered by Fronius system monitoring,
you must adjust the following firewall settings:
49049/UDP
output
Sending of service messages
x
Connection to Fronius system monitoring established via Fronius Solar.web
x
Service messages are sent via Fronius Solar.web.
Configure the firewall so that data can be sent from the Fronius system monitoring IP address to port 49049/UDP of "fdmp.solarweb.com".
DSL routers usually allow data to be sent over the internet and so do not normally have to
be configured for this purpose.
To enable access to the web interface of Fronius system monitoring from outside the LAN:
Configure the network router so that requests on port 80/TCP are forwarded to Fronius
system monitoring.

Run the Solar Web wizard and follow the instructions.
The Fronius Solar.web homepage
or
the Fronius system monitoring web page is displayed.
Information to
help you work
through the Solar
Web wizard
The solar web wizard consists of 5 steps:
1. General
General system data (e.g. system name) is entered here
2. Service password
Enter (and make a note of) the service password
3. IO assignment
Settings for the IO interface are entered (see also General for IO assignment on page 97)
4. System overview
Settings for the entire PV system are entered (see also System overview on page 110)
5. Dynamic power
Settings for dynamic power reduction are entered (see also EVU Editor – Dynamic power
reduction on page 116)
Once you have worked your way through the Solar Web wizard, an automatic process is
triggered to calibrate all the components. This involves charging the Fronius Solar Battery
fully. After that, the system automatically starts in the set operating mode.
This calibration charging process is also performed automatically during actual operation
after a number of charging and discharging cycles. When this calibration charge is performed depends on a number of different factors, such as the average state of charge or
the energy throughput through the battery. The time can therefore vary depending on the
time of year as well.
If the "permit battery charging from PSC grid" setting is deactivated, this calibration charging process relies exclusively on energy from the photovoltaic system when operating under normal conditions. Depending on the insolation conditions and size of the systems
concerned, the charging process can take a very long time.
If the "permit battery charging from PSC grid" setting is activated, the calibration charging
process is performed by drawing a constant current from the photovoltaic system and PSC
grid.
IMPORTANT! The automatic process for fully charging the battery may result in energy being drawn from the PSC grid. The process can take several hours and cannot be aborted.
Testing emergency power mode
NOTE! During grid-connected operation, the inverter recognises and stores the
direction of phase rotation in the household network. If the inverter is immediately
operated in emergency power mode without first establishing a grid connection,
no information is available regarding the direction of rotation. The inverter will
feed in power with a default direction of rotation, which can lead to faults in threephase consumption in the household network.
Emergency power mode should be tested once it has been installed and set up for the first
time. A battery state of charge of over 30% is recommended when in test mode.

Obtain IP address statically
The user enters a fixed IP address for Fronius system monitoring and also defines
the subnet mask, the gateway address and the DNS server address (from the provider) manually.
(5)
Obtain IP address dynamically
Fronius system monitoring fetches the IP address from a DHCP server (DHCP =
Dynamic Host Configuration Protocol).
The DHCP server must be configured so that the same IP address is always assigned to Fronius system monitoring. This means that you always know which IP
address can be used to reach the Fronius system monitoring datalogger.
If the DHCP server supports the DNS dynamic updates function, a name can be
assigned to Fronius system monitoring in the "Host name" field. As a result, the
connection to Fronius system monitoring can be established using the name instead of the IP address.
For example: Host name = sample_system, domain name = fronius.com
Fronius system monitoring can be reached via the address "sample_system.fronius.com".

Settings – Energy Manager
General
The Fronius hybrid inverter always controls the system by adjusting it in line with the target
value set at the metering point. In "Automatic" operating mode (factory setting), the system
is adjusted so that 0 W is achieved at the feed-in point (maximum self-consumption).
The target value still applies even if another source feeds energy in at this metering point.
However, in this case:
The Fronius Smart Meter must be installed at the feed-in point
The option that allows the battery to be charged by another producer must be activated (see Battery management section on page 108).
Own consumption optimisation
Option for selecting automatic or manual self-consumption optimisation
Target value at the metering point
If you opt for "manual" under "Own consumption optimisation", you can select the target
value at the metering point and choose between "Bezug" [Consume] and "Feed-in" here.
Operating mode
"Automatic" or "Off" can be selected for emergency power mode.
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.
Remaining battery capacity
If emergency power mode is set to "Auto", during grid-connected operation energy is
drawn from the battery until the battery capacity specified here is reached.
SOC warning level
A warning is output when the residual capacity of the battery specified here is reached in
emergency power mode

Battery management
reserve battery capacity:
This function is required to prevent available energy
from going to waste if the photovoltaic system is overdimensioned or in the case of dynamic power reduction. Up until a certain time of day, energy is only fed
into the Fronius Solar Battery if dynamic power reduction is active or if the amount of PV power available on the Fronius hybrid inverter exceeds what can
be delivered on the AC side (overdimensioning) - see
example below.
Consequently, storage space is "reserved" in the Fronius Solar Battery to accommodate this operating
scenario. Standard energy management (self-consumption optimisation) only resumes once the set
time is reached.
battery charge from producers in the home network:
If further decentralised producers are installed in the household and are 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 household network and fed into the Fronius Solar Battery for charging purposes via the Fronius hybrid inverter.
You can restrict how much power is consumed by the Fronius hybrid inverter by specifying
the maximum AC power. The maximum power consumption is limited to the AC nominal
output of the Fronius hybrid inverter.
To ensure smooth operation in conjunction with other energy producers, it is important to
install the Fronius Smart Meter at the feed-in point. The Fronius hybrid inverter and other
energy producers must be connected to the public grid via the Fronius Smart Meter.
Calibration charge:
At regular intervals, the Fronius hybrid inverter automatically charges the Fronius Solar
Battery until it is full for the purpose of calibrating all the components. This process can be
started manually here.
IMPORTANT! When calibration charging is activated, normal operation is interrupted and
the system may draw energy from the PSC grid. The process can take several hours and
cannot be aborted.
108
If the "permit battery charging from PSC grid" setting is deactivated, this calibration charging process relies exclusively on energy from the photovoltaic system. Depending on the
insolation conditions and size of the systems concerned, the charging process can take a
very long time.
If the "permit battery charging from PSC grid" setting is activated, the calibration charging
process is performed by drawing a constant current from the photovoltaic system and PSC
grid.
Example of reserve battery capacity
Example 1 - dynamic power regulation is active:
Actual state:
Symo Hybrid 5.0-3-S
PV output = 5 kWp
Max. grid power feed 60% (3 kW)
Fronius Solar Battery 6.0
Reserve battery capacity: unrestricted charge from 14:00
System behaviour at 11:00 (5 kW PV output):
Household network consumption = 1 kW
Grid power feed = 3 kW
Battery charge = 1 kW
System behaviour at 15:00 (5 kW PV output):
Household network consumption = 1 kW
Grid power feed = 0.8 kW
Battery charge = 3.2 kW (nominal charging power for the Fronius Solar Battery 6.0)
Example 2 - more PV power is available on the Fronius Symo Hybrid than can be released on the AC side (= overdimensioning)
Actual state:
Symo Hybrid 5.0-3-S
PV output = 8 kWp
Fronius Solar Battery 6.0
Reserve battery capacity: unrestricted charge from 14:00
System behaviour at 11:00 (7 kW PV output):
Household network consumption = 1 kW
Grid power feed = 5 kW
Battery charge = 1 kW
System behaviour at 15:00 (7 kW PV output):
Household network consumption = 1 kW
Grid power feed = 2.8 kW
Battery charge = 3.2 kW (nominal charging power for the Fronius Solar Battery 6.0)
109
EN
Once calibration is complete, the system automatically reverts to the operating mode that
was set originally.
This calibration charging process is also performed automatically during actual operation
after a number of charging and discharging cycles.
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 indicated
underneath the battery symbol.
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).
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.
110
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 connected
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
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.
The meter is automatically detected after it has been connected. The location of
the meter and, if required, the meter converter ratio can be configured under Settings.

111
EN
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 household
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 consumption is limited to the AC nominal output of the Fronius hybrid inverter.

power reduction is only activated if the battery is full or cannot be charged for some other
reason.
In this example, no more than 3000 W may be fed into the grid at the grid feed-in point.
However, any loads that are located between the inverter and the grid feed-in point can

Maximum SOC in operation:
Maximum state of charge (SOC) of the Fronius Solar Battery that is not to be exceeded during normal operation.
Once the set value has been reached, the Fronius hybrid inverter stops feeding energy into the Fronius Solar Battery.
Regardless of this setting, the Fronius hybrid inverter still performs an automatic
process at regular intervals, which charges the Fronius Solar Battery up fully
(100% SOC) for the purpose of calibrating all the components.
(2)
Minimum SOC in operation:
Minimum state of charge (SOC) of the Fronius Solar Battery that is not to be undershot during normal operation.
Once the set value has been reached, the Fronius hybrid inverter stops drawing
energy from the Fronius Solar Battery.
This state of charge may be temporarily undershot as a result of battery self-discharge.
(3)
Maximum charging current:
Maximum charging current of the Fronius Solar Battery.
(4)
Maximum discharge current:
Maximum discharge current of the Fronius Solar Battery.
(5)
Service: Battery module replacement
Service mode allows you to replace and extend the battery modules and is also intended for test purposes.
When this mode is activated, the Fronius Solar Battery is charged or discharged by
means of a 10 A current or with the maximum inverter power, regardless of any other parameter settings. The charging or discharging process continues until the
state of charge stands at 53% (the SOC of new battery modules on delivery). The
process can be aborted at any time.
Once this SOC has been reached, the system maintains it until Service mode is
deactivated again.

Displaying status
codes
The inverter performs a system self diagnosis that automatically detects many faults that
may occur and shows them on the display. This means you are promptly made aware of
malfunctions in the inverter and the photovoltaic system, or of any installation or operating
faults.
If the system self diagnosis has detected a specific fault, the associated status code will be
shown on the display.
IMPORTANT! Status codes may sometimes appear briefly as a result of the inverter's control response. If the inverter then continues working with no sign of any problem, this
means that there was no fault.
Total failure of the
display
The display can be supplied with power in three different ways. The display will only remain
dark if all three methods fail. In this case:
Check the AC voltage on the inverter connection sockets:
The AC voltage must be 220/230 V (+10% / -5%) or 380/400 V (+10% / -5%).
Check the DC voltage of the solar modules on the connection sockets of the inverter:
The DC voltage must exceed 180 V.
Check the DC voltage of the battery on the connection sockets of the inverter: The DC
voltage must exceed 120 V.
Status codes –
Class 1
Class 1 status codes generally only arise momentarily and are caused by the public grid.
Example: The grid frequency is too high and the inverter may not feed any energy into the
grid owing to a standard. There is nothing wrong with the device.
The initial response of the inverter is to disconnect itself from the grid. The grid is subsequently checked during the stipulated monitoring period. If no further problem has been detected by the end of this period, then the inverter will resume feeding energy into the grid.
The GPIS SoftStart function is activated according to the country setup:
After cutting out due to an AC error, the output power of the inverter is continuously increased in line with the national guidelines.

Applicable standards and guidelines
Fronius hybrid inverter:
CE mark
The devices conform to all the requisite and relevant standards and guidelines that form
part of the relevant EU directive, and are therefore permitted to display the CE mark.
Emergency power operation
This version of the hybrid inverter is only intended for use in grid connected photovoltaic
systems. A device update is required from the manufacturer in order to generate power independently of the public grid. As well as providing functional enhancements for the hardware and software, this update also includes relevant user documentation.
The hybrid inverter is delivered ready for supplying emergency power.
Power outage
The standard measurement and safety procedures integrated into the inverter ensure that
in the event of a power outage, the feed-in of energy is immediately interrupted (e.g.
switch-off by the energy supplier or damage to lines).
