2 Safety
2.1 Intended use
The sonnenProtect 2500 is an backup power unit designed to supplement the sonnenBatterie hybrid 9.53. The sonnenProtect- in conjunction with the appropriate storage system of the sonnen GmbH – serves to supply power in the event of a power failure. Any other use is considered improper use.
Improper use poses a risk of death or injury to the user or third parties as well as damage to the product and other items of value. The following points must therefore be observed in order to comply with the intended use of the product: · Only operate the sonnenProtect together with the right storage system. · The minimum capacity of the storage system required for the operation of the
sonnenProtect is 5 kWh (2 battery modules). · The sonnenProtect must be installed by a licensed electrician. · The sonnenProtect must only be connected to the storage system as described here. · Generators (e. g. a PV system) must never be connected after the output of the
sonnenProtect. · Intended use includes observing this document as well as all accompanying product doc-
umentation of the appropriate storage system. · The sonnenProtect must only be installed and used at suitable installation location. · The transport and storage conditions must be observed. Especially the following uses are not permissible: · Operation in flammable environments or areas at risk of explosion. · Operation in locations at risk of flooding. · Operation outdoors.
Failure to comply with the conditions of the warranty and the information specified in this document invalidates any warranty claims.
2.2 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 electricians. 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.
2.3 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 knowledge 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.

2 | Safety
2.4 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.
2.5 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 storage system is switched off. As the sonnenProtect is connected to the inverter of the storage system, this means that the voltage from the inverter also flows into the 5 min sonnenProtect. Therefore: Do not open the sonnenProtect. Do not remove any plastic covers.

4.1 Function
A storage system with sonnenProtect automatically switches from grid to backup operation (and vice versa). The two operating modes are described in the following.

In grid operation the consumers connected to phase L1 to L3 and the consumers connected to the backup circuit (1 – 4) are connected to the public electricity grid (9). All consumers 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.

5 sonnenProtect
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 operation) to green (backup operation).
Electrical power generated by the PV system (8) continues to be used by the storage system 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.
KD-676 | 1001838 | EN | 01
11 / 20
4 | Operation
If the discharge has stopped due to the minimum state of charge, the storage system remains 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 exceeds the minimum limit, the surplus power is used to supply the electrical consumers in the backup circuit.
4.1.3 Backup operation – overload behaviour
Case 1: Overload detection by fuse The integrated fuse (miniature circuit breaker F3.P) of the sonnenProtect protects the entire 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 integrated 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: 1. The overload is removed: The storage system restarts the backup operation after a few
minutes and the eclipse changes from orange to green. 2. 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.

5 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.

6 Maintenance and Cleaning
6.1 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).
Maintenance interval Every 6 months
Action to be taken Check the function of the RCD with help of the Test key.
Table 2: Checking function
6.2 Cleaning
NOTICE
Use of unsuitable cleaning agent and/or excessive water
Material damage because of scratched surfaces and/or damage caused by penetration of water! Do not use scouring cloths, sponges or cleaning agent. Use only moist cloths, not wet cloths, to clean the system. Do not use water jets.
Carefully clean the outside of the sonnenProtect with a clean, moist cloth. For tougher dirt, use a small amount of household dishwashing detergent on a moist cloth.
