External Power Meter
Recording Energy Flows with External Power Meters
1 External Power Meter
1.1 Recording Energy Flows with External Power Meters
External power meters can be connected to every Solar-Log™ model via the S0 input and/or the RS-485
bus.
Solar-Log™ devices have a varying number of SO inputs:
S0 inputs
Solar-Log™ Number of S0 inputs
Solar-Log 300, 1200 and 2000 2 x S0-In and 1 x S0-Out
Solar-Log1000, 500 1 x S0-In/Out
Solar-Log200 1 x S0-In
Solar-Log 250 1 x S0-In
Note
The Solar-Log™ requires a S0 pulse duration of 30-40 ms. That is why we recommend using
SDS tested meters that we offer.
We cannot guarantee the functionality of other products.
In addition, the maximum length between the power meters and Solar-Log™ should not exceed
10 m.
Note
Consumption meters can be assigned to plant groups.
It is only possible to assign a meter after a rule with the calculation of self-consumption has
been activated in the power management configuration Configuration | Feed-in Management.
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
(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 refers to 2 kW (energy)
Phase 3 refers to 1 kW (energy)
With an accumulating meter, this results in a total of 0 kW.
An example of an accumulating meter is the Janitza UMG 104 or the Solar-Log™ Pro380 Mod.

Solar-Log™ Meter Operating Modes
Explanation of the Solar-Log™ Meter Operating Modes
2 Solar-Log™ Meter Operating Modes
2.1 Explanation of the Solar-Log™ Meter Operating Modes
There are various setting options when configuring meters in Solar-Log™. These are in particular:
• Battery meter (bi-directional meter):
• Records the battery charges and discharges.
• Deactivated: The recording of consumption has been or is deactivated.
• Meter for the entire plant: The entire production from all of the inverters.
• Sub-consumer: Meter to record the individual consumption from appliances that was already
recorded with a consumption meter.
• Utility Meter (U+I) (only Solar-Log 2000): Meter for control and reduction functions - including
current measurements if necessary with current transformers.
• Utility Meter (U) (only Solar-Log 2000): Meter for control and reduction functions - only voltage
measurements.
• Consumption meter: Meter that only records the consumption.
• Consumption meter (Bi-directional meter): Meter that records consumption and production collec-
tively - the actual consumption is determined by monitoring the inverters.
• Inverter mode: The meter values are considered inverter values.

3 General Information on Wiring
3.1 Wiring for S0 meter
The SO connection for external power meters is connected to a 6-pin S0A-In/Out connection (S0-IN A and
S0-OUT) or to a 4-pin S0-IN B as follows:

Place a cable bridge between pin 3 and 4 on the Solar-Log™.
3.2 Wiring for RS485 meter
The meter's RS485 output can be connected to any RS485 interface (A, B and C) on the Solar-Log™.
Overview
• 2-pin wiring
• The communication address has to be assigned.
Installation steps
• Switch off the meter and Solar-Log™.
• Connect the meter to the Solar-Log™.
3.3 Wiring meters to record self-consumption
There are two options to record self-consumption via the Solar-Log™:
• Measuring just the consumption.
• Measuring with bi-directional measurements (two-way measurements) at the grid connection point
behind the utility company meter.
Fundamentally, a separate meter needs to be installed to record energy consumption.
The meters used by utility companies generally cannot be used to send data to the Solar-Log™.

General Information on Wiring
Wiring meters to record self-consumption
3.3.1 Meter connection options to record the total consumption via an
RS485/S0 interface.
This meter has to measure the total consumption of the house.
The meters installed by grid operators, or two-way meters, cannot be used to implement
this function.

Wiring meters to record self-consumption
3.3.2 Meter connection options for bi-directional recording of the total con-
sumption via only an RS485 interface.
If there is feed-in in a sub-distribution, the option mentioned above can be used. In this
case, the the amount of feed-in power and power obtained from the grid can be recorded with a bi-direc-
tional meter. With this,
the Solar-Log™ can calculate the consumption.

4.1 Solar-Log™ PRO380 Mod
Selections available under Solar-Log Pro
Overview
• The communication address has to be assigned.
• 2-pin wiring
• Installation steps
• Switch off the meter and the Solar-Log™.
• Connect the meter to the Solar-Log™.
Note
The communication address is set to 1 by default, but can be adjusted if several meters are
connected to one RS485 bus. Maximum of 32 meters per RS485 bus
Connect the meter to the Solar-Log™.
The wiring is done using a
• self-made cable connection with a terminal block connector.
4.1.1 Connection diagram
according to circuit type 1000 (DIN 43856)
Input "L1, L2, L3" Supply line input phase "L1, L2, L3"
Output "L1, L2, L3" Supply line output phase "L1, L2, L3"
Terminal "N" Neutral conductor connection "N"
Terminal 18, 19 Sopulse output "consumption" (terminal 18 = "+")
Terminal 20, 21 Sopulse output "supply" (terminal 20 = "+")
Terminal 22, 23 ModBus connection terminal 22 -> A, 23 -> B
Terminal 24, 25 External tariff switching (230V AC)
The SO signal for the supply is not used when a meter
is connected to the Solar-Log™.

house/plant (IN)
(installation position according to the arrow system)
►As battery meter (bi-directional): Connection to the production/grid (IN) – connection
to the battery (OUT)
Cable connection via RS485:
Solar-Log™ terminal strip connector Solar-Log™ PRO380 Mod
Terminal PIN
►1 22 (A)
►4 23 (B)
Note
If the meter is the last device on the bus, it has to be terminated at connection block 22 and 23
with a resistor (120 ohm / 0.25W).
Note
The Solar-Log™ PRO380 Mod cannot be connected to the inverters with a single bus.
For this reason, use one RS485 connection for the inverters and one RS485 connection for the
Solar-Log™ PRO380 Mod.
►A combination with an M&T Sensor on the same bus is possible.
Possible meter operating modes for the Solar-Log™ PRO380 Mod via RS485:
• Battery (Bi-directional meter)
• Meter for the entire plant
• Sub-consumption meter
• Consumption meter
• Battery (Bi-directional meter)
• Inverter mode
