1 Introduction
This installation manual is intended for use by solar energy technicians and professional electricians.
User manuals are available for operating the Solar-Log™.
The wiring for the inverters is described in detail in the Component Installation Manual.
The Solar-Log™ must only be used by persons who have fully read and understood this installation manual
before installing, operating and/or servicing the device.
Our product documentation is being constantly updated and expanded.
The current versions of the documents can be downloaded from our website:
www.solar-log.com.
The descriptions in this manual refer to firmware version 3.5.2

Updating from Firmware 2.x to 3.x
3 Updating from Firmware 2.x to 3.x
The following note is for the Solar-Log 200, 500 and 1000 models when updating to firmware version 3.x.
In order to update to 3.x, the Solar-Log™ must at least be running firmware version 2.x. The latest firmware
can be downloaded from our website:
http://www.solar-log.com/de/service-support/firmware.html.
Note!
After installing firmware 3.x, it is no longer possible to downgrade to the previous ver-
sions. It is not possible to install older firmware versions.
The following changes occur when upgrading to 3.x:
The data transfer function is no longer available.
•
The Smart Energy section has been completely revised. If the function External Switch (only Solar-
•
Log 1000) is used, this part needs to be reconfigured after the update.
The settings and function of the power management have to be checked and, if need be, reconfig-
•
ured.
With the new modern web interface, old web browsers might sometimes cause problems with the
•
functionality. We recommend using the current version of Mozilla's Firefox, Google's Chrome, Microsoft Edge or Microsoft's Internet Explorer.
As part of the update, the Solar-Log™ has a data reformatting process running in the background. This
process starts once the update is finished. This process could last several hours and the Solar-Log™ will
operate and react slower until the update finishes.

Note!
We recommend checking and cleaning SIM cards once a year.
The contact points of the SIM card could start corroding due to humidity and should
be cleaned regularly to ensure trouble-free operations.
9.2 Solar-Log™ Meter (Solar-Log 300 and 1200)
The Solar-Log Meter version of the Solar-Log™ has an integrated interface to connect up to six current
transformers (CTs). This optional Meter interface makes it possible to measure generating units (produc-
tion meter) and consumption from individual appliances.
Fig.: Connection for current transformers (Solar-Log™ Meter)
The current transformers (CTs) can record the current flow (AC) of one or two phase appliances in vari-
ous combinations. The output is calculated based on a defined reference voltage or one calculated by the
Solar-Log™.
Note!
With the Solar-Log 300 and 1200 Meter, the mounting direction of the current
transformer (CT) is not relevant because the energy flow direction cannot be defined. It lacks a direct voltage measurement.

Characteristics of the Meter interface
The current transformer may not exceed a maximum output or secondary current of 200 mA. The input /
rated current is calculated by the maximum amount of power that is to be measured and has to be select-
ed for each measuring point.
The current transformer's rated measuring ratio can be defined for each current transformer input.
The current transformers have to be set up in a way so that only one current-carrying conductor is mea-
sured. Cables with multiple wires cannot be measured.
The maximum cable length between the current transformers and Solar-Log™ depends on the cable dia-
gram and the load of the current transformer.
We recommend a maximum cable length of 30 meters with a diameter of 0.75 mm2 for our products.
For other current transformers, please consult the manufacturer's specifications in regard to cable length
and the wiring diagram.
Note!
Due to the lack of a voltage supple for the measurements, only the apparent power
– not the active power – is measured. Since in most cases the active power should
be measured, we recommend measuring with a power meter when there is a large
percentage of reactive power.

12.1 Sensor Box Basic and Professional
These sensors record both Irradiation sensor and module temperature values.
The solar radiation sensor must be fitted in such a way that the sensor's solar cell and the plant's modules
are aligned as similarly as possible to the sun, i.e. the sensor must have the same alignment and inclination.
The sensors should be positioned in a way to best ensure that:
as little overshadowing as possible occurs
•
and snow cover does not interfere disproportionately with the sensor functions.
•
To achieve this, it is best to fit the sensor on the side or above the solar module. Fitting bars can normally
be used as a fitting surface with modules that are parallel to the roof protrusion. In other cases, a suitable
fitting support may have to be added.
Note!
When using inverters with RS422 communication, do not operate the sensor on the same
bus.
Wiring the Sensor Box Basic and Professional to the Solar-Log™
The wiring is done using a
4-wire data cable which also includes the 12 V power supply and the data connection to the
•
Solar-Log™.
The sensors are connected to the Solar-Log™ via the RS485 interface parallel to the inverter bus or
•
via a free RS485 interface. Please pay attention to the notes in the component database. Sensors
cannot be connected to the same bus with some inverters.
The cable shielding must be connected with an equipotential bonding system.
•
A separate power supply is generally not required.
The connection cable can be extended (max. 50 m). In this case, however, it must be ensured that a power
supply voltage of at least 8 V is provided for the Sensor Box Basic at the end of the cable and 10.5 V for
the Sensor Box Professional. If necessary, a separate power supply can be integrated into the bus wiring.
The cable must also be suitably protected in outside areas. The cabling in inside areas can consist of a
shielded data cable.

12.3 Ripple Control Receiver
The Solar-Log™ PM+ series contains an additional 6-pin interface which allows up to two ripple control
receivers or telecontrol plants each with four signals to be connected.
Wiring
The relay contacts for the ripple control receiver are connected to the Solar-Log™ PM+ via the 6 pin PM+
interface on the top side of the Solar-Log™.
Fig.: 6-pin PM+ interface
The ripple control receivers used by grid operators utilize various numbers of relays. These relays are la-
beled differently and have different reduction levels and/or shift factors cos (Phi).
To ensure the highest degree of flexibility, the reduction levels specified by the grid operators, together
with their signals from the ripple control receiver, can be evaluated by the Solar-Log™ via a maximum of
four digital inputs for each.
In order that the Solar-Log™ PM+ can evaluate the signal from the ripple control receiver, it needs to be
wired to the control voltage (for active and reactive power) from the PM+ interface. The control contracts
normally operate as make contracts; that means they are closed for the respective command.
The control voltage from Pin 1 is used for the active power command.
The control voltage from Pin 6 is used for the reactive power command.
The control voltage is connected to the common contact of each relay. The relay output (closed contact)
is then connected to a digital input of the PM+ interface.
Fig.: The basic principle of wiring the PM+ interface to the ripple control receiver for active power commands
See the Appendix for more ripple control receiver connection examples on page of this installation
manual.
Further configurations of feed-in management are carried out via the Solar-Log™ PM+ web interface in the

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 refers to 2 kW (energy)
Phase 3 refers to 1 kW (energy)
With an accumulating meter, this results in a total of 0 kW.
Examples of accumulating meters are the Janitza UMG 104 and the Inepro Pro380-Mod.

Inepro 1250D
Connecting accessories
Only one Inepro RS 485 meter can be used for
each Solar-Log™ interface.
These meters cannot be used together at the same bus input with inverters that are con-
nected to RS422 (e.g. Fronius).
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 recom-
mend 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 min-
utes depending on the amount of data on the devices.
51
Connecting accessories
Note!
Inepro meter
Inepro meters are automatically given 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 cor-
rectly detected the meter.
All RS485 meters have to be terminated with an 120Ω resistor between the two pins
used.

12.8 Installation Utility Meter / Janitza UMG 104 (only Solar-Log 1000 and
2000)
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 the voltage measurements are needed to control voltage-dependent reactive power via the Q(U)
function (Although, it is still recommended to perform voltage and current measurements to check that
the reduction function is operating properly). Current and voltage measurements are needed for the other
functions.
The previous chapter explains how to wire the Utility Meter to the Solar-Log™. This chapter deals with con-
necting the Utility Meter for measurements in low- and medium-voltage power grids.
Utility Meter supply voltage / Janitza UMG 104:
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) are 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.

If the Solar-Log™ should Obtain its IP address automatically (DHCP), this switch needs to be activated.
This is only possible if the Solar-Log™ is connected to an Internet router with DHCP enabled. When the
search is started, the Solar-Log™ attempts to obtain an IP address through an Internet router. This can take
up to 60 seconds.
If the DHCP server is disabled in the router, the network settings must be configured manually. If neces-
sary, please consult a network specialist who can assign a suitable network address in regard to IP address,
Subnet mask and Gateway, for example.
If the Solar-Log™ is to have a fixed IP address, the Obtain IP address automatically (DHCP) switch needs
to be deactivated. The following fields need to be adjusted according the network's configurations.
IP address
The address needs to be entered manually in order to allow remote PC access, when using a direct PC con-
nection or a router without DHCP service.
Subnet mask
The Subnet mask is 255.255.255.0 by default and must be the same for every device in the subnet.

this inaccuracy.
All yield data are stored internally without any correction factor. This factor is applied only when the
data are displayed. The factor can therefore be adjusted at any time.
The formula for calculating the correction factor is as follows:
Yield on power meter / Yield at inverter * 1000
If the inverter does not have a display, the correction factor must be left at 1000 initially, and the fac-
tor can then be determined after about a week or at later times.
Define the module field.

•
Information on the maximum storage temperature for the EGO Smart Heater
By default, the maximum boiler temperature is adjusted with the rotary switch on the EGO Smart Heater.
To be able to control the temperature from the Solar-Log™, the rotary switch on the EGO Smart Heater has
to be set higher than the value from the Solar-Log™ because the settings from the rotary switch determine
the maximum temperature for external control
Example:
If the rotary switch is set to 40°C and the Solar-Log™ to 60°C, the settings from the Solar-Log™ will be
ignored and the value from the rotary switch will be applied. The range for the rotary switch has to be set
higher so that the Solar-Log™ can assume control. In the example to 60°C.
For this reason, we recommend setting the rotary switch to a maximum of 80°C – or the maximum broiler
temperature that is not to be exceeded – when the Solar-Log™ is to control the temperature externally.
The Solar-Log™ can control the temperature when it is in the range below the set maximum value.
Note!
The EGO Smart heater is an intelligent appliance. The available reported surplus is re-
ported to the intelligent electrical appliances and can be consumed by them.

•
• There are different selection options for the Charge limitation function in this section:
• Not controlled - The Solar-Log™ only records the charging data without
• any control of the charging process.
• Surplus - The electric car only changes when there is enough PV power available. The So-
lar-Log™ takes the defined minimum charge level into consideration. In this case, the release
of power for the charging station corresponds to the amount of surplus.
• Surplus / minimum charge - This ensures that the car always reaches its minimum charge
level even when no PV power is available. When there is an energy surplus, the Solar-Log™
informs the charging station.
• Always charge - The Solar-Log™ allows the charging station to consume power without any
restrictions, regardless of the production or surplus levels.
• min. Charge Current [mA] - The defined minimum charging power value is taken into account.
• max. Charge Current [mA] - The defined maximum charging power value is taken into account.
Off delay [Min.] (only when used with the Charge limitation „Surplus“) - The switch-off delay
option defines when the charging process should be stopped after the previous surplus is no
longer available. This option prevents the charging process from being interrupted by shortterm fluctuations in the amount of available surplus. The time factor can be defined from 1 to 60.

Note about forced charging via wall switch (X1)
If a wall switch is installed and connected to X1 on the charging station, the charging station is allowed via
the Solar-Log™ to consume the defined maximum power levels without any restrictions, regardless of the
production or surplus levels.
If a wall switch has not been installed, the Solar-Log™ configuration defined for the current limiting functi-
on can be set to „always charge.“ This also allows for charging according to the defined maximum power
level.
