6 Connector Assignments and Wiring
The following connecting cables, which may be needed for various purposes, are not included in the pack-
age content.
• To connect a router, you need a network cable with the appropriate length. If you want to connect the
Solar-Log™ directly to your PC or laptop, you need to use a crossover cable.
• Cable to connect the Solar-Log™ to an inverter.
• Sets of prefabricated cables are available as accessories suitable for the inverter concerned. The
length of these cable sets is 3 m.
• If you want to connect several inverters to Solar-Log™, you need suitable cables and connectors to
connect the inverters to each other.
• When wiring with CAT cables, the twisted pair of wires should be used.
6.1 Notes on wiring the connections
The wiring of the inverters and accessories needs to be carried out with the greatest care and attention.
The most frequent source of errors when installing the Solar-Log™ is faulty wiring.
For this reason, we recommend:
• Wiring with high quality cables
For example: LIYCY >=0.14mm2or Cat 5/7 SSTP
• Refer to the manufacturer's specifications in regard to UV resistance and mounting type when wiring
in outside areas.
• A larger cable diameter is recommended for longer distances.
• Use ferrules with flexible wires
• Twist the corresponding wire pairs and shielding
• Wire from left-to-right.
• Wire from light to dark.

15
Connecting the inverters
7 Connecting the inverters
As each inverter manufacturer uses different wiring connections and connectors, the corresponding data
cables must be adapted correctly.
• See Chapter„Belegung und Verkabelung der Anschlüsse“ for terminal block connector wiring diagrams
for the connection to the Solar-Log™
• Please refer to the Component Connection Manual when connecting inverters supported by the So-
lar-Log™. (Download from https://www.solar-log.com/en/support/downloads/manuals)
Note
Solare Datensysteme GmbH supplies suitable connection cables for most inverter manu-
facturers.
Always read the manufacturer-specific instructions for connecting the data cable. You will find these in-
structions in the manufacturer's documentation.
However, when assigning the inverter wiring on the Solar-Log™, follow the instructions in this manual, oth-
erwise the inverters will not be detected by Solar-Log™.
Danger
Risk of death by electric shock if inverters are opened.
Never open the inverter housing when the inverter is connected to power.
See the chapter "Switching inverters off."
Always read the installation and safety instructions given in the manual for the corre-
sponding inverter.

16
Connecting the inverters
7.1 Switch o the inverters and the Solar-Log™.
Switching inverters off
Before a making a cable connection between the Solar-Log™ and the connections inside the inverter and
before installing an interface card in the inverter, always turn off all of the inverters first.
To do this, read the manufacturer's documentation for the inverter, and proceed as follows:
• Disconnect the AC side.
• Disconnect the DC side.
• Wait at least 5 minutes until the condensers in the inverters have discharged.
Turn the Solar-Log™ off.
• Hold down reset button for 10 seconds and then release it as soon as the components LED turns ( )
Orange. The Solar-Log™ will shut down and can be disconnected from the power supply (see chapter
18.1.1 "Reset Button" for more information).

17
Connecting accessories
8 Connecting accessories
8.1 External power meter
External power meters can be connected to the Solar-Log™ via the RS-485 bus.
The energy recorded by these meters can be used for numerous applications:
• Generator Mode:
This mode is used, for example, for inverters that are not directly supported by Solar-Log™.
• Total yield meter:
This mode is used to record the energy production of several inverters.
• Consumption meter:
This mode is used to measure power consumption and to make it possible to display this data.
Note
We recommend using the meters that we have tested and offer.
We cannot guarantee the functionality of other products.
Note
Refer to the Meter Connection Manual for all of the supported meters and their wiring
diagram. Download it from our website:
https://www.solar-log.com/en/support/downloads/manuals

18
Connecting accessories
8.1.1 External power meters/accumulating meters
With multiple phase meters, a basic distinction is made between phase-exact and accumulating meters.
Accumulating meters provide the total values from all three phases. The meter calculates the total output
(also to and from the grid) of the individual phases and provides this total as a single value.
In the example:
Phase 1 supplies 3 kW via an inverter (single phase).
Phase 2 draws 2 kW (energy)
Phase 3 draws 1 kW (energy)
With an accumulating meter, this results in a total of 0 kW.
Examples of accumulating meters are the Janitza UMG 104/UMG 604 and the Solar-Log™ Pro380-Mod.

Other connections
9 Other connections
9.1 USB
The Solar-Log 50 comes with an USB connection. This USB connection can only be used for USB sticks and
not, for example, for a direct PC or laptop connection.
Note
When a USB stick is connected, the Solar-Log™ automatically saves a backup in the
backup folder. A maximum of 10 backup files are saved in the directory. Older backup
files are automatically deleted.
The backup is saved on the USB stick in the directory /Backup with the following file names:
• solarlog_backup_YYMMDD.dat:
