electrical shock. The storage system inverter also contains capacitors which
carry voltage even after the storage system is switched off.
Do not open the storage system.

Operation manual
Page 9of 37
2.5 Handling the battery modules
2.5.1 Information on the sonnenModule 4 battery modules:
Figure 1: sonnenModule4 battery module
-The battery modules have a nominal voltage of 102.4 VDC and but operate in
series which raises the operating voltage above 120 VDC resulting in the
application of DVC C.
-The battery modules are utilising high-performance Lithium-Iron-Phosphate (LFP)
-The battery modules contain no metallic Lithium.
The battery modules installed in the storage system are protected by
multiple protective devices and can be operated safely. Despite their
careful design, the battery cells inside the battery modules may corrode or
experience thermal runaway in the event of mechanical damage, heat or a
fault.
This can have the following effects:
High heat generation on the surface of the battery cells.
-Electrolyte may escape.
-The escaping electrolyte may ignite and cause an explosive flame.
-The smoke from burning battery modules can irritate the skin, eyes
and throat.
Therefore, proceed as follows:
Do not open the battery modules.
Do not mechanically damage the battery modules (pierce, deform, strip
down, etc.)
Do not modify the battery modules.

Operation manual
Page 10 of 37
Do not allow the battery modules to come into contact with water
(except when extinguishing a fire in the storage system).
Do not heat the battery modules. Operate them only within the
permissible temperature range.
Keep the battery modules well away from sources of ignition.
Do not short-circuit the battery modules. Do not allow them to come
into contact with metal.
Do not continue to use the battery modules after a short circuit.
Do not deep-discharge the battery modules.
In the event that module contents are released:
Do not enter the room under any circumstance.
Avoid contact with the escaping electrolyte.
Contact the fire services.
2.6 Conduct in case of a fire
Fire may occur with electrical equipment despite its careful design. Likewise, a fire in the
vicinity of the equipment can cause the storage system to catch fire, releasing the
contents of the battery modules.
In the event of a fire in the vicinity of the product or in the storage system itself, proceed
as follows:
Only firefighters with appropriate protective equipment (safety gloves, safety
clothing, face guard, breathing protection) are permitted to enter the room
where the burning storage system is located.
There is a danger of electrocution when extinguishing fire while the storage system is
switched on. Therefore, before starting to extinguish the fire:
Switch off the storage system to electrically isolate it.
Switch off the main switch in the building.
If the storage system and/or main switch cannot be safely switched off:
Observe the minimum distances specified for the extinguishing agent used. The
storage system works with an output voltage of 230 V (AC) and is therefore
considered a low-voltage system.
-A storage system fire can be extinguished using conventional extinguishing
agents.

Operation manual
Page 11 of 37
-Water is recommended as an extinguishing agent in order to cool the battery
modules and therefore, prevent thermal runaway in battery modules which are
still intact.

4.1 Basic operating principle
Figure 4: sonnenBatterie Evo Connection Concept
The sonnenBatterie Evo is an intelligent storage system that monitors and controls
energy production, consumption, and storage in the house. The storage system is
connected to the grid via the main distribution board.
The sonnenBatterie Evo can work with existing or newly installed PV systems. The PV
array does not connect to the storage system directly. The storage system uses a power
meter and current transforms to monitor PV power generation and energy consumption
in the building.
The sonnenBatterie Evo offers three modes of operation: Self-consumption, Backup, and
Time of Use.
4.1.1 Self-consumption mode
Self-consumption is the part of the generated PV power that has been either consumed
at home or stored in the battery. This is the default mode of operation.

Operation manual
Page 19 of 37
Generation > Consumption
If the generation of PV power is higher than the consumption such as at midday, there is
a surplus of electrical energy. In this case the surplus energy is used to charge the
battery of the storage system.
If the entire portion of the surplus cannot be charged into the battery, the remaining
surplus is fed into the public electricity grid.
Consumption > Generation
If the consumption is higher than the generation of PV power such as in the evening,
there is a deficit of electrical energy. In this case the battery of the storage system is
discharged to even out as much of the deficit as possible. If the entire deficit cannot be
compensated by discharging the battery, the remaining deficit is covered by the public
electricity grid.
The storage system also acts as a backup power supply, meaning that if the utility grid
goes out, your appliances will be powered by the batteries of the storage system
conditioned upon installer connection of back up function.
4.1.2 Backup mode
Figure 5: sonnenBatterie Evo Connection Concept

Operation manual
Page 20 of 37
sonnenBatterie Evo storage system automatically switches from grid to backup
operation and vice versa. In the event of a grid failure, the storage system automatically
detects the grid outage and will disconnect itself from the public electrical mains and will
create a micro-grid using the power from the batteries. Appliances connected to
essential loads circuit in the house will be supplied with electrical power. Appliances
connected to normal loads circuit in the house will not be supplied with electrical power.
During the backup operation, the micro-grid produces grid-quality voltage and
frequency so that any grid-connected PV inverter in the micro-grid will continue to
operate. Therefore, during backup operation, the essential loads circuit will be powered
by the energy stored in the battery modules and the PV energy generated from the PV
array. The generated PV power will also charge the battery modules, depending on
generation and consumption levels.
The PV array will first power the loads on the essential load circuit, with any excess
energy charging the batteries in the storage system. If there is insufficient PV to cover
the loads, the storage system will discharge its batteries to meet the demand. The
storage system can also turn the PV inverter off if the battery modules become fully
charged.
To prevent battery overcharging while in backup mode, the storage system will perform
a frequency shift by raising the frequency to a value outside the PV inverter’s operating
range. This shift in frequency will disconnect the PV inverter from the micro-grid while
the storage system will maintain the power supply to the loads. The storage system will
reduce the frequency to 50 Hz once the state of charge falls below a certain threshold
to allow for a charge event. The PV inverter will then automatically detect the frequency
adjustment and re-connect to the micro-grid.
Microgrid Re-Enabling
If the battery SOC drops to a minimum threshold during backup operation:
1. The micro-grid will be deactivated, and the system will go to ‘standby mode’. The
essential loads and the external PV inverter on the micro-grid will disconnect
consequently.
2. The system will remain in ‘standby mode’ until the system time reaches the
“Reenabling time one”, as previously set in the commissioning process. Then, it will
