• All repairs on the storage system must be performed by authorised service technicians only.
• The replacement of battery modules must be performed by authorised service technicians only. When replacing batteries, replace with the same type and number of batteries or battery modules.

Voltage inside the storage system

• The storage system contains live electrical parts, which poses a risk of 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.

Handling the battery modules

Information on the sonnenModule 4 battery modules:

• The battery modules have a nominal voltage of 102.4 VDC and operate in series which raises the operating voltage above 120 VDC resulting in the application of DVC C.
• The battery modules are utilizing 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.
• Electrolytes 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.
• 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.

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.
• 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.

Function

Basic operating principle

• 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.

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.

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.

Backup mode

• 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 re-enable the micro-grid. The essential loads and the AC-coupled PV inverter will re-connect consequently.
3. If there is sufficient excess PV energy to charge the battery, the micro-grid will be maintained.
4. Otherwise, the micro-grid will be deactivated, and the system will go to ‘standby mode’ again. The essential loads and the AC-coupled PV inverter will disconnect consequently.
5. The system will repeat steps 2 to 4 according to the “Reenabling time two” and “Reenabling time three”, as previously set in the commissioning process. The system will shutdown after the third attempt to prevent further battery discharge.

Blackstart Functionality

• In case of a grid-outage the storage system will automatically enable and switch-over to microgrid operation depending on the state-of-charge of the batteries. Alternatively, the system operator has the ability to manually switch on the storage system without the grid being present by using the blackstart button. In the process, the storage system will also activate the microgrid.

For correct operation, please follow the steps below:

1. Ensure the storage system is turned on prior to using the blackstart button. Green power button in ON position.
2. Switch on the storage system using the green power button.
3. Press and hold the blackstart button for about 60 seconds.

• If there is sufficient excess PV energy to charge the battery, the micro-grid will be maintained.
• Otherwise, the micro-grid will be disconnected, and the system will go to ‘standby mode’ again. The essential loads and the AC-coupled PV inverter will disconnect consequently.

Time-of-Use mode

• This mode is similar in function to self-consumption except that the storage system will charge the batteries from the grid during the specific time windows selected by the customer. By setting the storage system to time of use mode, customers can store electricity in the battery when electricity prices are low, and then use this stored electricity to supply the household appliances at times of peak rate. The batteries are prevented from discharging during the selected windows of time of use.
• If your electricity provider company offers you time of use electricity tariffs, in which there is a price difference between the peak and off-peak rates, you may consider setting the storage system to time of use mode.
• Please contact your sonnen support team to set up the ToU mode.
