General System Function
Description of use
The sonnenBatterie eco is an intelligent
storage system that monitors and controls energy
production, consumption, and storage in the
house.
The sonnenBatterie eco can work with existing
or newly installed PV systems. The solar inverter
and eco storage system connect to the same
distribution panel. Solar modules do not connect
to the sonnenBatterie directly.
The storage system uses two power meters
to monitor solar power production and energy
consumption. When production is higher than
consumption, such as at midday, the eco stores
the excess energy in its lithium iron phosphate
(LiFePo4) battery modules. When consumption is
higher than production, such as in the evening, the
storage system releases the energy. In doing so,
the storage system allows you to use solar power
at night, reducing your power bill and increasing
the value of your investment in renewable energy.
The storage system also acts as a backup power
supply, meaning that if the utility grid goes out,
your appliances will remain powered.
The illustration below shows how the storage
system manages solar power (1) and power from
the utility grid (2) to maximize your energy
independence and savings on your power bill.
Modes of operation
The sonnenBatterie eco offers three
complementary modes of operation: Self-
consumption, Backup, and Time of Use. Self-
consumption mode ensures that you are using the
power you generated even when the utility grid
power is available; backup mode makes that self-
generated power available in the event of a grid
power outage.
In addition, many utility companies are moving
to a Time of Use-based rate tariff, in which
electricity costs more during high-demand time
periods. The sonnenBatterie eco can maximize
your cost savings by using your stored battery
power during the high-cost part of the day
and recharging from solar and optionally with
electricity purchased from the grid at the lowest
offered rates.
Self-consumption mode
The following images illustrate the interaction
between the storage system, the PV system, and
the utility grid in self-consumption and backup
modes:
1
2

10
The DC power that is generated by the PV array
(A) is converted to AC power by means of an
inverter (B). The meters (C) and (D) measure the
current electrical power in watts. The production
meter (C) measures the power production, the
consumption meter (D) measures the power
consumption in the house. If the production is
higher than the consumption, the surplus will be
stored in the battery modules (E). The storage
system’s inverter (F) converts the AC power
to DC power while the battery modules (E) are
charging. When the production is lower than the
consumption, electric power will be released
from the battery modules to power the loads. The
storage system’s inverter (F) converts the DC
power of the battery modules (E) to AC power.
The utility’s power meter (G), measures the power
supply and the power fed back to the grid (H) by
the PV array (if applicable). The storage system
will not discharge its batteries to the grid in
normal operation.
Backup mode
In backup mode, the storage system provides
grid-quality power to keep the PV array working
when the grid goes down. During the day, the
PV array initially powers the household loads
fed by the backup sub-panel and uses any excess
power to charge the battery modules, depending
on production and consumption levels. The
house can then be powered at night by the solar
energy stored in the battery modules. If there is
insufficient PV during the day to cover the loads,
the storage unit will discharge its batteries to
meet household demand.
In backup mode, the 10-, 12-, 14-, and
16-kilowatt models of the sonnenBatterie eco
storage system will automatically isolate the house
from the utility grid using a 200A automatic
transfer switch. Once the grid comes back online,
the storage system will automatically reconnect to
the utility grid.
In the event of grid failure, the smart storage
system can also turn the PV array off if there
are no household loads to be fed and the battery
modules become fully charged. If the loads are
small and the PV production is high, then this
could happen multiple times per day.

System touchscreen interface
The sonnenBatterie eco is designed to run
without user intervention in most cases. The LCD
screen on the physical unit has a number of menus
to display information and control the unit.
In a normal installation, the screen above will
serve as the home screen. This screen displays
the unit's state of charge, the home's energy
autonomy, production and consumption statistics,
and the amount of power that is going into or
coming out of the unit.
When the storage unit is in power outage
mode, the screen above will be the home screen.
This screen displays the unit's state of charge,
production and consumption statistics, and the
amount of power that is going into or coming out
of the unit. The screen will also show an estimated
length of backup power remaining (in hours). This
estimate is based on energy usage for the last 30
seconds and therefore may change frequently.
The menu screen, accessed by pressing the grid
of six dots in the upper right corner of the screen,
allows you to access the Settings screens.
The Settings screen allows you to shut down the
unit by pressing the Shutdown button.

com page, you will arrive at your sonnenBatterie
dashboard. This diagram provides an overview
of your sonnenBatterie’s state of charge, your
home’s solar PV production, your home’s energy
consumption, and the energy drawn from the
utility grid.
Sonnen Dashboard
Your sonnenBatterie’s current State of Charge,
or how much energy is stored in the battery, is
represented by the large bars on the right side
of the diagram. The upper bar is the real State
of Charge, which is always 5% higher than the
State of Charge. (This is because there is a built-in
buffer of 5% for best practice).
Next, on the top left hand corner labeled
‘Production,’ is your solar PV production. It is
located under the graphic of a sun and PV panel.
This number is a real-time measurement of how
much energy, in kilowatts, you are generating with
your solar PV system.
On the top right, under the graphic of the
house is your home’s energy consumption. This is
a real-time assessment of how much energy the
loads in your home are consuming in kilowatts.
Finally on the bottom left, under the transmission
tower graphic, you can find the amount of energy
being purchased from the grid.
Please note, this information is also provided
on the status page of the sonnenBatterie App and
Web Portal.
There will also be two tabs on the left side. The
System tab will provide more technical information
about the battery, such as the model number,
