Fronius Energy Solution for Pakistan

2
WHY A STORAGE SOLUTION?
/ The self-consumption rate of PV systems is often low
/ Consumption and generation at different times (day/night)
/ Self-consumption of solar power is becoming
increasingly attractive
/ Falling feed-in tariffs
/ Rising electricity prices
/ Decentralised energy storage relieves the grid
/ Storage can balance fluctuating generation
/ Storage reduces the need for grid expansion

THE FRONIUS VISION OF 24 HOURS OF SUN
/ 24H Sun: This is the future of power generation over the coming decades
/ The challenge facing renewable energies is to provide power regardless of the time of day
or year, and thus ensure an optimum supply
/ Short-term energy storage units are an important step towards 24H Sun

4
CHALLENGES FACING STORAGE UNITS
/ More complex systems
/ Solutions can quickly become complex as generally several components interact - however,
simple solutions are required!
/ Solutions must be adapted to the situation in the household concerned
/ Storage unit size, positioning of batteries, load management, etc. must be adjusted individually
- adaptable systems are required
/ The system operator expects a convenient emergency power function
/ Nobody investing in photovoltaics and batteries wants to sit in the dark in the event of a power
failure, but wants to be able to use all rooms - it should be possible to supply the whole house!
/ Wiring an emergency power circuit is expensive and does not meet the requirements of the
system operator

Fronius Energy Package
The personal storage solution for
24 hours of sun.

THE HEART: THE FRONIUS SYMO HYBRID
/ The Fronius Symo Hybrid is a photovoltaic inverter
and battery inverter in one device
/ A battery can be connected directly to it in addition to the PV
generator
/ In case of a power failure, the Fronius Symo Hybrid can
work as a stand-alone unit
/ The Fronius Symo Hybrid is the heart of the Fronius
Energy Package for 24 hours of sun

THE FRONIUS SYMO HYBRID
SnapINverter
The same simple installation and
commissioning process as per the Fronius
Galvo and Fronius Symo.
WLAN and web server
WLAN and web server already on board: connect directly
using Smartphone, tablet or notebook via WLAN!
Battery know-how
Fronius has been working on the careful use of
batteries for many decades. This know-how helps to
increase the efficiency and service life of the storage
system!
Feed-in management
Dynamic feed-in control can be
implemented easily and direct connection to
the ripple control receiver is possible

WHAT IS THE FRONIUS SOLAR BATTERY?
/ The battery for the Fronius Energy Package
/ Lithium iron phosphate (LiFePO4) with high voltages (120-460V*)
/ The advantages of lithium iron phosphate
/ Long service life, short charging times, high depth of discharge
/ No release of oxygen or hydrogen gas
/ Highest quality with 7 year Fronius current value warranty
/ The advantages of a battery with high voltage
/ Low losses in the DC line and smaller cross-sections due to lower currents
/ Thus the battery can be placed at a greater distance from the inverter
/ The same cable as that to the PV generator can be used
/ Scalability from 4.5 kWh to 12.0 kWh nominal capacity
* Voltage dependent on battery capacity and state of charge

10
WHAT IS THE FRONIUS SMART METER?
/ Fronius Smart Meter
/ Bidirectional meter to optimise self-consumption and recording of
household load curves
/ Preconfigured to use with Fronius Symo Hybrid
/ Can be easily installed in the switch cabinet (DIN rail installation)

11
THE EMERGENCY POWER SWITCHOVER FACILITY
/ Supply in case of power failures
/ In case of a power failure, the Fronius Symo Hybrid continues to supply
not just one phase, but electricity to the whole household
/ Three-phase asymmetric emergency power supply
/ Emergency power switchover facility
/ Disconnects the system safely from the grid and reconnects it again
/ Consists of an AC contactor with 12 V auxiliary contact
/ Optional: additional AC contactor (redundancy), external grid monitoring
/ Can be fitted in the switch cabinet with standard components - Fronius can
provide the required circuit diagrams for this

12
INDIVIDUAL CAPABILITIES OF THE SOLUTION
/ Use solely as a photovoltaic inverter
/ The customer starts with a normal grid connected system
and can extend the battery and emergency power function at
any time.
/ Emergency power function without battery
/ The customer also uses the emergency power function
without battery; current is available depending on the
insolation.
/ Full version with battery and emergency power
/ The customer wants maximum self-consumption or
emergency power during the night and supplements the
system with the battery. This can also be charged from the
mains.

13
INDIVIDUAL CAPABILITIES OF THE SOLUTION
/ Full version with battery, but without emergency
power
/ The customer wants maximum self-consumption, but does
not require the emergency power function. The battery can
also be charged from the mains.
/ Due to this flexibility, the system can be adapted to
the individual requirements of each customer!

MULTI FLOW TECHNOLOGY
/ With Multi Flow technology, it is possible to manage
various DC and AC energy flows in parallel:
/ Energy can be provided by the modules and by the battery
simultaneously.
/ Energy from the modules can be conducted in the battery
and the home network simultaneously.
/ The battery can be charged not only from the DC side, but
also from the AC side. This makes the inverter suitable for
AC-coupled retrofitting.
 The inverter manages the energy flows so that the greatest
possible self-sufficiency is achieved.

15
APPLICATION: A HIGH DEGREE OF SELF-CONSUMPTION
/ The aim: No current to flow through the meter - no feed-in, no supply from the grid
/ During the day
/ Energy to be supplied by the PV system to storage and all phases in the household (good
weather)
/ Energy to be supplied by the PV system + from storage to all phases in the household (bad
weather)
/ During the night
/ Energy to be supplied from storage to all phases in the household

16
APPLICATION: EMERGENCY POWER OPERATION
/ The aim: The household can be supplied with power even in case of a power failure.
/ Energy to be supplied by the PV system + from storage to all phases in the household
/ The Fronius Symo Hybrid supplies the building with up to 5 kW.
/ Supply is 3-phase and, depending on requirement, asymmetrical.
/ The transfer switch ensures the safe isolation from - and reconnection to - the grid.

17
APPLICATION: CHARGING FROM THE AC SIDE
/ The aim: Energy can also be stored in the battery from the AC side
/ Charging of the battery during long periods of bad weather (e.g. solar modules covered by snow)
to have a full battery available in case of power failures and to increase the service life of the
battery
/ Charging of the battery during periods of low-cost electricity tariffs
/ Charging of the battery during periods of excess power in the grid (contribution to grid stability)
/ Charging of the battery from other AC sources in the household (e.g. CHP, wind turbine, etc.)

The benefits for the
system operator

Maximum independence:
sun by day, sun by night and sun
during power outages.
30

31
MAXIMUM INDEPENDENCE
/ Independence from increases in electricity prices due to the high degree of self-
consumption
/ Independent supply in case of power failures. Heating, fridge, TV and so on simply continue
to run - thanks to the three-phase emergency power supply!
/ In this way (partial) self-sufficiency is already possible

Perfectly adapted solutions - as
individual as the customers
32

33
INDIVIDUALLY ADAPTABLE SOLUTIONS
/ The customer only needs to buy what he actually needs
/ Entry into photovoltaics without storage is possible - with the knowledge that it is easy to
upgrade at any time!
/ No problem with the space required
/ Battery and inverter can be placed where there is space.
/ The storage size can be adapted to the requirements

Revolutionary operation: extremely
simple commissioning, impressive
monitoring
34

35
REVOLUTIONARY OPERATION
/ WLAN and web server with datalogger already on board: connect directly using
Smartphone, tablet or notebook via WLAN
/ User-friendly graphical user interface (integrated web server)
/ Simple configuration of system monitoring via an assistant, using Smartphone, tablet or
notebook
/ Internet connection via WLAN or LAN - to easily use Fronius Solar.web, the Fronius
Solar.web App or Fronius Solar.TV

36
/ Web interface on inverter - accessible via WLAN or LAN:

Maximum efficiency - more solar
power, fewer losses!

41
MAXIMUM EFFICIENCY
/ The Fronius Solar Battery is connected on the DC side
/ No multiple conversions (DC  AC  DC  AC)
required, as is the case for batteries connected on the AC
side
/ Transformerless inverter
/ High total efficiency due to low conversion losses
