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.

2.5 Voltage inside the sonnenProtect
5 min
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:
Disconnect the sonnenProtect and the storage system from the power supply (see
Disconnecting the sonnenProtect from the power supply).
Only then can the sonnenProtect be opened.

DANGER Electrical work on the storage system and electrical distributor
Danger to life due to electrocution!
Switch off the storage system to electrically isolate it.
Disconnect the relevant electrical circuits.
Secure against anyone switching on the device again.
Wait five minutes so the capacitors can discharge.
Check that the device is disconnected from the power supply.
Only authorised electricians are permitted to carry out electrical work.
Due to the extension of the storage system hybrid 9.53 by a sonnenProtect
2500, the system is ready for emergency power as well as operation in island-
ing mode. These are functionalities that may need to be specified when regis-
tering a storage system with the distribution system operator (DSO).
This means that under certain circumstances it may be necessary to change in-
formation on the storage system at the DSO or to re-register it.
Recommended procedure for the electrical installation
Carry out the steps in the following order to ensure the smooth electrical installation of
the sonnenProtect:
1. Read sections ‘Electrical consumers in emergency operation [P.14]’ and ‘Implement-
ing the emergency circuit(s) [P.14]’ and, together with the operator of the storage
system and the sonnenProtect, define how the emergency circuit or circuits are to be
set up. The on-site circumstances must always be taken into account during this pro-
cess, because with electrical installations where there are few separate circuits, it can
be difficult to integrate all of the desired electrical consumers in the emergency circuit
or to integrate only the consumers which should be supplied with backup power.
2. Carry out the necessary revision work on the distributor in the building. It is essential to
ensure that all electrical cables meet local and national regulations in terms of their di-
mensioning.
3. If the emergency circuit or circuits are installed accordingly, the sonnenProtect can be
connected and the necessary additions can be made to the storage system (see the
following sections).
4. When all steps have been implemented and the electrical installation is complete, con-
tinue with section ‘Commissioning [P.20]’.

14 / 28 Installation instructions sonnenProtect 2500
5.1 Installing the emergency circuit(s)
5.1.1 Electrical consumers in emergency operation
Before installation, the installer must explain or clarify with the operator the following
points:
• Emergency operation does not offer the same output as grid operation.
• Three-phase current is not available during emergency operation (as only one phase is
supplied with power).
•Which electrical consumers should be supplied with power in emergency operation? The
current paths in the building network must be installed in such a way that the consumers
which are relevant in the event of a grid outage are connected to an independent circuit
(emergency circuit). The electrical consumers which are crucial for the operator in
emergency operation are relevant here. Different consumers which may be important
during a grid outage are specified in the sample calculation presented below.
•How much capacity of the storage system should be reserved as an backup buffer? The
following example, in which a utility room and other important functions within a single-
family home are to be supplied with power, can be used to determine this. This example
is based on a grid outage lasting one hour (the individual power consumption values are
estimated values).
Electrical consumer Power con-
sumption
[W]
Active during grid
outage
[h]
Electrical work
[kWh]
Lighting 500 1 0.5
Freezer 600 0.25 0.15
Heating 700 0.25 0.175
Router, telephone 10 1 0.01
Refrigerator 600 0.25 0.15
Alarm system, grid-connected smoke
detector
50 1 0.05
Total 1.04
In this example the total power requirement for a grid outage lasting one hour is approx.
1.1kWh, in order to maintain the function of all the listed consumers.
Use this calculation to determine with the operator which emergency buffer should be
set, taking the total capacity of the storage system and other requirements (e.g. from
sonnenFlat tariff) into account (see Setting the backup buffer [P.20]).
5.1.2 Implementing the emergency circuit(s)
Basics for the formation of the emergency circuits:
• For systems with emergency power capability, the power distribution must be separated
into emergency power authorised and not emergency power authorised parts.
• All components within the emergency power authorised part must be clearly identified
by lettering (or graphic symbols).
At any time observe further local and national requirements and guidelines regarding
emergency power supply!

Electrical installation | 5
KD-535 | 1000050 | EN | X00 15 / 28
When undertaking electrical work on the distributor in the building, the following must be
taken into account, among other things:
1. How is the wiring set up to the desired backup consumers?
– Is independent wiring already in place?
– Do the existing circuits include electrical consumers that should not be supplied
with power in backup operation?
– Can the existing wiring be split?
– If the circuits cannot be split, the connected wattage of the consumers which
should not be supplied with backup power needs to be taken into account. If loads
are too high, the circuit breaker for the sonnenProtect will trip, and then none of
the electrical consumers in the backup circuit will be supplied with power.
2. Can the electrical distributor in the building be adapted to suit the new circumstances?
– Is there enough space to install the necessary circuit breakers and other compon-
ents in the distributor?
5.2 Positioning components in the electrical distributor
The following components must be installed in the electrical distributor for the
sonnenProtect:
•Miniature circuit breaker (MCB) | typeB | 20A
A miniature circuit breaker with typeB tripping characteristics and a nominal current of
20A must be installed upstream of the input for the sonnenProtect.
5.3 Wiring components in the electrical distributor
Condition:
üThe emergency circuit has been properly installed. The information in section Installing
the emergency circuit(s) [P.14] was observed at all times.
Wire the sonnenProtect and the other components in the electrical distributor as
shown in the following figure.
Note:
• The figures ‘Circuit diagram overview - electrical connection at single-phase mains
[P.16]‘ and ‘Circuit diagram overview - electrical connection at three-phase mains
[P.17]’ show the installation of a sonnenBatterie hybrid 9.53 as an example, which has
been installed in a single- or three-phase network in accordance with the specifications
in the product documentation and to which a sonnenProtect has been added (grey
marked area).
