4 Electrical installation
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.
NOTICE
Observe maximum line lengths
„
None of the lines connected to the storage system (mains line, ethernet
line, other data lines) are allowed to exceed a maximum length of 30 m.
4.1 General information about installation
„
Always observe the specifications in the installation instructions for the eco 8.0 stor-
age system.
Important note:
• The conditions described in the installation instructions for the relevant storage system
apply to the installation of the residual current device (RCD) marked in figure 'Circuit
diagram overview - electrical connection of the pro 2.0 [P. 11]’. If an RCD of the re-
quired type is already installed, it is not necessary to install an additional RCD.
• In the case of an existing installation of three eco 8.0 storage systems connected in par-
allel , the installation of the power meters must be changed.
4.2 Selecting the measurement concept
• The standard measurement concept (also referred to as the CP measurement concept
or setup 1) is recommended for power measurement of a sonnenBatterie pro 2.0. This
corresponds to the structure of the installation described in the following section Wiring
the components [P. 11].
• The GP measurement concept (also referred to as setup 4) should only be used if the
standard measurement concept can’t be implemented or if the individual components
for the power measurement are already installed as the GP concept and elaborate con-
version is to be avoided. Please note that the GP measurement concept can lead to a
lower efficiency of the storage system.
• Measurement concept GP (setup 4) must not be used if several pro 2.0 storage systems
which are connected to the same production unit (e. g. pv system), are connected in
parallel.
