• Intended use includes observing this document as well as all accompanying product doc-
umentation of the appropriate storage system.
• The sonnenProtect must only be 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 spe-
cified 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 authorised electri-
cians. Authorised 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 company for which the electrician works must be certified by sonnen GmbH.

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.

In grid operation the consumers connected to phase L1 to L3 and the consumers connec-
ted to the emergency circuit (1 - 4) are connected to the public electrical mains. 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.

3 Consumer connected to phase L3 8 PV system
4 Consumer connected to emergency circuit 9 Public electrical mains
5 sonnenProtect
The sonnenProtect (5) automatically detects a grid outage. As soon as the voltage of the
electrical mains drops to approx. 180V, the connection to the public electrical mains (9) is
disconnected.
Emergency power is generated after max. 15 seconds. The consumers connected to emer-
gency circuit in the house (4) are thereby supplied with electrical power. Consumers con-
nected to the phase L1, L2 or or L3 (1 - 3) will not be supplied with electrical power.
The switchover from grid to emergency operation is signaled by the Eclipse (light ring) on
the storage system. The color of the Eclipse changes from white (normal operation) to
green (offgrid operation).
Electrical power generated by the PV system (8) continues to be used by the storage sys-
tem to supply the consumers in the emergency circuit and to charge the battery.
The storage system with sonnenProtect switches from emergency to grid operation as
soon as the public electrical mains (9) start to deliver electrical power again.
Automatic stop and resumption of the emergency 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.

4 | Operation
12 / 20 Operating instructions sonnenProtect 2500
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 emergency circuit.
4.1.3 Emergency 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 emergency operation (Eclipse will
turn green), but the electrical consumers in the emergency circuit will no longer be sup-
plied 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 emergency 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 emergency operation after a
few minutes and the eclipse changes from orange to green.
2. The overload remains: The storage system tries to resume emergency operation twice.
If it is switched off a third time, the emergency operation remains disabled until the
grid outage is over. The eclipse will continue to glow orange.
