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.

3.1 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:

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.

General Information on Wiring
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.

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.

Note
The Inepro 1250D cannot be used on the same bus input with RS422 connected inverters.
Note
All three phases have to be connected for the Solar-Log™ to accurately detect the meter.
If an Inepro 1250D is used, the PRG button on the meter must be pressed and held down during
entire detection process.
If it is not possible to hold down the PRG button during the whole process, we recommend
provisionally connecting the meter to the Solar-Log™ with a short cable after the installation in
order to be able to press and hold down
the PRG button during entire detection process.
In a second detection attempt with the inverter, the meter is then detected by the Solar-Log™
even if the PRG button is not pressed.
The detection of an Inepro 1250D in an existing installation can take up to 15 minutes. After the
detection, a restructuring of the data takes places which can take up to 45 minutes depending
on the amount of data on the devices.
Note
The Inepro 1250D meters are automatically assigned the mod bus address 234 by Solar-Log™
during the detection process.
This address is therefore not allowed to be used for other devices.
After the configuration, the display on the Inepro meter alternates between the meter status
and the address display (ID=EA). This can be used to check if Solar-Log™ has correctly detected
the meter.

7 Janitza UMG 104 (Utility Meter)
7.1 Janitza UMG 104
The Solar-Log™ Utility Meter is a universal metering device. It can be integrated in both low- and medium-
voltage networks (via a transformer) and is needed for various functions:
• controlling voltage-dependent reactive power via the Q(U) function
• controlling reactive power at the feeding point
• recording the measurement data needed for the response signals sent to the grid operator
Only voltage measurements are required for voltage-dependent reactive power reduction Q(U). However,
we still recommend using both current and voltage measurements to be able to check that the reduction
function is operating properly. Current and voltage measurements are needed for the other functions.
Utility Meter supply voltage:
• 95-240Vac, 45-65Hz or 135-340Vdc
The Utility Meter's measuring inputs have the following limits:
• Voltage line conductor AC (without a voltage transformer): 10…300 V AC
• Voltage phase AC (without a voltage transformer): 17…520 V AC
• Current (without a current transformer) 0.005, 7.5 A
• Frequency of the fundamental component: 45 ..65 Hz
The limit may not be exceeded. For this reason, a measuring transformer needs to be installed for most
applications.
We recommend the following transformer ratio:
• Voltage: Secondary 100V
e.g. at 20kV grid converter 20000:100V
• Current: Secondary 5A
e.g. 100:5A
Note
The Utility Meter that we use is produced by the company Janitza.
Refer to the Janitza UMG 104 manual for further technical details.
We cannot guarantee the functionality of other Janitza devices.
►The operating modes Utility Meter (U / U+I) is only possible with the Solar-Log 1000 and
2000.
Note
The Utility Meter 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
Utility Meter.

Procedure
• Enter the supply voltage into the Utility Meter
Note
We recommend using a fuse to safeguard the connection lines for the supply voltage. Please
follow the instructions in the Janitza UMG 104 manual.
Note
Supply voltages that do not correspond to the specifications on the rating plate can cause mal-
functions and damage the device.
Caution
The inputs for the supply voltage are dangerous to touch.
Note
The measurement voltage must in effect be at least 10V or an exact measurement is not possi-
ble.
