Requirements for the electrician
- Improper installation can result in personal injury and/or damage to components. For this reason, the sonnenProtect must only be installed and commissioned by licensed electri-cians. Licensed electricians must meet the following criteria:
- The electrician must be a person with a technical knowledge or sufficient experience to enable him/her to avoid dangers which electricity may create.
- The electrician must has successfully completed the sonnen Australia installer training and have valid installer accreditation at the time of installation.
Operating the product
- Incorrect operation can lead to injury to yourself or others and cause damage to property.
- The sonnenProtect must only be operated as described in the product documentation.
- This device can be used by children from the age of eight (8) years old and individuals with impaired physical, sensory or mental capabilities or individuals with limited know-ledge and/or experience of working with the device, as long as they are supervised or have been trained to safely use the device and understand the resulting risks of doing so. Children must not play with the device.
Product modifications or changes to the product environment
- The sonnenProtect must only be used in its original state without any user modifications and only when in perfect working order.
- Safety devices must never be overridden, blocked or tampered with.
- The interfaces of the sonnenProtect and the storage system must be connected in ac-cordance with the product documentation.
- All repairs on the sonnenProtect must be performed by authorised service technicians only.
Voltage inside the sonnenProtect
- The sonnenProtect contains live electrical parts, which poses a risk of electrical shock. The storage system inverter also contains capacitors which carry voltage even after the stor-age system is switched off. As the sonnenProtect is connected to the inverter of the stor-age system, this means that the voltage from the inverter also flows into the sonnenProtect.
Therefore:
- Do not open the sonnenProtect.
- Do not remove any plastic covers.

Operation
Function
A storage system with sonnenProtect automatically switches from grid to backup opera-tion (and vice versa). The two operating modes are described in the following.
Grid operation – no grid outage
- Consumer connected to phase L1
- Consumer connected to phase L2
- Consumer connected to phase L3
- Consumer connected to backup circuit
- sonnenProtect
- Storage system
- Battery of the storage system
- PV system
- Public electricity grid
In grid operation the consumers connected to phase L1 to L3 and the consumers connec-ted to the backup circuit (1 – 4) are connected to the public electricity grid (9). All con-sumers in the house are supplied with electrical power. The storage system controls – as described in the product documentation of the storage system – the energy flows in the building.
Backup operation – grid outage
- Consumer connected to phase L1
- Consumer connected to phase L2
- Consumer connected to phase L3
- Consumer connected to backup circuit
- sonnenProtect
- Storage system
- Battery of the storage system
- PV system
- Public electricity grid
-
The sonnenProtect (5) automatically detects a grid outage. As soon as the voltage of the electricity grid drops to approx. 180 V, the connection to the public electricity grid (9) is disconnected.
Backup power is generated after max. 15 seconds. The consumers connected to backup circuit in the house (4) are thereby supplied with electrical power. Consumers connected to the phase L1, L2 or or L3 (1 – 3) will not be supplied with electrical power. -
The switchover from grid to backup operation is signaled by the sonnen Eclipse (light ring) on the storage system. The color of the sonnen Eclipse changes from white (normal opera-tion) to green (backup operation).
-
Electrical power generated by the PV system (8) continues to be used by the storage sys-tem to supply the consumers in the backup circuit and to charge the battery.
-
The storage system with sonnenProtect switches from backup to grid operation as soon as the public electricity grid (9) starts to deliver electrical power again.
Automatic stop and resumption of the backup operation
- The storage system with sonnenProtect generates electrical power until a minimum state of charge of the battery is reached. Thereafter, no further discharge is allowed.
- If the discharge has stopped due to the minimum state of charge, the storage system re-mains in this state until the PV system starts to produce electrical power again. From then on, the batteries of the storage system are charged and as soon as the state of charge ex-ceeds the minimum limit, the surplus power is used to supply the electrical consumers in the backup circuit.
Backup operation – overload behaviour
- Case 1: Overload detection by fuse
- The integrated fuse (miniature circuit breaker F3.P) of the sonnenProtect protects the en-tire system against overload.
- When the fuse trips, the storage system will still be in backup operation (Eclipse will turn green), but the electrical consumers in the backup circuit will no longer be supplied with power!
- In this case, switch off the electrical loads or reduce their power consumption and then switch on the miniature circuit breaker F3.P in the sonnenProtect.
Case 2: Overload detection by storage system
- In special overload cases, the control of the storage system reacts earlier than the integ-rated fuse of the sonnenProtect. In this case, the miniature circuit breaker inside the sonnenProtect does not trip, the backup power is instead stopped by the control of the storage system. The eclipse of the storage system signals this by turning orange.
When this happens, there are two options:
- The overload is removed: The storage system restarts the backup operation after a few minutes and the eclipse changes from orange to green.
- The overload remains: The storage system tries to resume backup operation twice. If it is switched off a third time, the backup operation remains disabled until the grid outage is over. The eclipse will continue to glow orange.
Setting the backup buffer
Proceed as follows to set what percentage of the capacity of the storage
system should be available for the sonnenProtect in the event of a grid
outage.
Conditions:
-
The storage system is connected to the router of the home network.
-

-
Change the percentage for backup-buffer to a desired value.
Switching off the sonnenProtect
- To switch off the sonnenProtect manually, the following procedure can be carried out.
- Switch off the storage system as described in the relevant product documentation. After switching off, the consumers connected to the backup circuit(s) can no longer be supplied with electrical energy from the battery of the storage system.
NOTICE: Deep-discharge of the battery modules
- Destruction of the battery modules!
- Do not disconnect the storage system from the public electricity grid for long periods of time.
- Never continue to operate battery modules which have been deep-dis-charged.
Maintenance and Cleaning
Checking function
- A residual current device (RCD) is installed in the sonnenProtect. The function of the RCD can be tested by pressing the test key (T). After pressing, the RCD must switch off (the backup circuit is interrupted).
