Electrical installation
The pre-wired sonnenProtect-Plus has simplified the installation of the sonnenBatterie
Hybrid 9.53 with backup functionality and integrability with an optional AC-coupled PV
system. It comes with all the AC MCBs, RCBO and sonnen Power Meter with CTs enclosed
within an IP66 outdoor enclosure. The sonnenProtect-Plus includes full pre-installed
labelling as prescribed within the application AS/NZS Standards.
Electrical work on the storage system, the backup product, 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.
Observe maximum line lengths.
The lines connected to the storage system (mains line, Ethernet line, other data lines) are
NOT allowed to exceed a maximum length of 30 meters.

Installing the emergency circuit(s)
6.1.1
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 supply is not available during emergency operation (as only one phase
is supplied with power).
•
The minimum capacity of the storage system required for the operation of the
sonnenProtect is 5 kWh (2 battery modules).
•
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
