2. Charge smarter
With the go-e Controller you manage the ener-
gy ows of buildings. As a result, depending on
the position of the sun and the current pow-
er demand in a building, charging processes
of electric cars can be controlled even more
smartly in interaction with go-e Chargers. You
can also use the device simply to monitor con-
sumers in the building.
The go-e Controller helps you as a so-called
energy management system (EMS) in an electri-
cal distribution system to collect measured va-
lues and make them available to other devices
in a network. This means in particular, that pho-
tovoltaic surplus charging and dynamic load ba-
lancing can be implemented with go-e Chargers
without any further programming knowledge.
Keep an eye on the power ows in your building
and maximize automatically the self-consump-
tion of your PV system when charging with go-e
Chargers. For the go-e Charger of the Gemini
series and Home series (V3) even with automa-
tic phase switching.
Control the charging process of electric cars
with dynamic load balancing to avoid overloa-
ding your power connection. If required due to
many power consumers running at the same
time, the charging power of the go-e Chargers
connected to the Controller is automatically ad-
justed.
The go-e Controller is compatible with all PV in-
verters* and AC electricity battery storage solu-
tions. Furthermore, compatibility with all go-e
Chargers and the go-e app is also given.
The Controller provides a graphical representa-
tion of power consumption in real time. Mea-
sured values acquired by the Controller are
collected directly via the current transformers
supplied and the voltage supply established by
the electrician. A 1-phase or 3-phase operation
of the Controller is possible.
Summarized:
The Controller manages an unlimited number
of Chargers so that they charge electric cars
when sucient power is available. Depending
on your preference, with and without power
from the grid.
The go-e Controller can be controlled directly
via a display. The go-e app makes it even more
convenient to use.
The Controller can be integrated into a network
via WiFi or Ethernet. The go-e Controller has
no shortage of other interfaces for connecting
to existing solutions: In addition to HTTP API,
MQTT and Modbus, a cloud API is also available
to integrate the go-e Controller.
Much of the information in this manual
is intended for the installer, who must
perform the installation and should
perform the basic conguration. The
settings for optimized charging proces-
ses and the connection of additional charging
stations to the Controller can be conveniently
implemented by the user in just a few steps via
the go-e app.
Tip: PV surplus charging can even
be combined with exible electricity
prices. This enables even more sustai-
nable and cost-eective charging.
We wish you much joy with your
go-e Controller.

4. Safety regulations/notes
Electrical protective measures,
installation, operation
All information on electrical installa-
tion is intended exclusively for a qua-
lied electrician whose training allows
all electrical work to be carried out in
accordance with the applicable natio-
nal regulations.
The go-e Controller must be mounted by a qua-
lied electrician in accordance with the comple-
te operating instructions. The installation must
be carried out in accordance with local, regional
and national regulations.
An electric shock can be fatal. Disconnect the
circuit from the power supply before making
any electrical connections.
The Controller is mounted on a top-hat rail.
Observe the permissible ambient conditions.
At ambient temperatures of more than 45 °C, a
safety distance of 10 mm to other devices in the
control cabinet is recommended. An ambient
temperature of 55 °C must not be exceeded.
The Controller should not be operated in the
immediate vicinity of ammable or explosive
substances, running water or heat-emitting
equipment.
Make sure that the power connection leading
to the go-e Controller is properly installed and
undamaged.
An RCD type A, 30 mA must be provided on the
building side, unless local regulations deviate
from this. Independently of this, a line circuit
breaker (recommendation: LS-3/B6) must be
provided. Do not fuse the go-e Controller with
more than 16 A.
General safety regulations
The go-e Controller is to be used ex-
clusively to collect measured values in
an electrical system and to pass them
on in a network in order to implement energy
monitoring, to maximize the self-consumption
of a PV system or to implement dynamic load
management in interaction with go-e Chargers.
Failure to comply with the safety regulations
can have serious consequences. go-e GmbH
disclaims any liability for damage caused by
disregarding the operating instructions, safety
regulations or warnings on the device.
Mains voltage - danger to life! Never use the
go-e Controller if the housing is damaged or
open.
If unusual heat is generated, do not touch the
go-e Controller and disconnect the power sup-
ply. In case of discoloration or distortion of the
plastic, contact customer support.
Wearers of electronic implants should keep at
least 60 cm away from the go-e Controller due
to electromagnetic elds.
The go-e Controller has the communication
interface WiFi 802.11b/g/n 2.4GHz. The WiFi is
operated on a frequency of 2.4Ghz, channels
1-13 with the frequency band 2412-2472Mhz.
The maximum transmit power of the WLAN is
20dBm EIRP.
The go-e Controller may only be operated on
fully functional protective devices. Connection
cables must be suciently dimensioned. We
recommend a cable cross-section of at least 1.5
mm².
The current transformers should be attached
in the direction of the current as described and
illustrated in the installation instructions. This
means that the arrows on the current transfor-
mers should point in the direction of the cur-
rent consumer.
Always use the current transformers supplied.
Alternative current transformers, which are
also suitable for higher currents, may be used
only after inquiry to go-e support and its conr-
mation in text form.

*If it is not possible to install the current sen-
sors with the arrow pointing in the specied
direction for space reasons, the sensors can
also be inverted via the Controller menu or
the app.
Now connect the WiFi antenna and/or the
Ethernet cable to the Controller.
For optimal reception, lead the at cable of
the WiFi antenna out of the installation distri-
butor to attach the top there.
7.
You do not want to connect any further sen-
sors? (This is not necessary for the PV surplus
optimisation.) Then restore the voltage sup-
ply. Next, follow the instructions from point 5
in chapter 9 Installation (additional sensors).
8.
For PV surplus optimisation, we need enough
sensors to measure the power from or to the
grid. For three-phase connection, plug the jack
plugs of three current transformers into the
designated inputs for current measurement.
For example, in sensors one to three. For sin-
gle-phase connection, use only one current
transformer. The easiest way to do this is to
measure directly at the mains connection.
Attach one current transformer per phase.
The two arrows on the current transformer
must point in the direction of the current.
When connecting to the power grid, which we
call the " grid", the arrow should point from
the power grid towards the house.*
Please note: A maximum of one current
transformer may be attached to one pha-
se.

If necessary, lay additional supply line. Insert
the conductors into the connecting clamp and
x it with a screwdriver. Also connect the neu-
tral conductor and the protective earth.
3.
Mount the go-e Controller on the DIN rail. We
recommend mounting according to the illus-
tration. However, the Controller can also be

9. Installation (additional sensors) The connection of a current transformer
is also sucient for measuring the cur-
rent of other 3-phase major consumers.
You can also use the current trans-
formers to measure the consumption
of individual circuits, such as lighting,
a boiler, air conditioner, sauna or heat
pump. When measuring these loads,
the arrow on the current transformer
should point in the direction of the
load.
The Controller now switches on and is
ready for operation after the system
has booted up. Most likely, the display
will still show wrong measured values,
we still have to assign the correct phase
and category to the sensors. Now you
have to carry out the initial congura-
tion. You can choose between these two
methods.
a) Commissioning/operation via the but-
tons and the display on the unit
b) Conguration via the app

3.
When using WiFi repeaters, remem-
ber that they extend your home
network and do not create a new
network with a dierent IP address.
This works best with repeaters from the
same brand of your access point or WiFi
router.
If you have already installed go-e Char-
gers, they will be automatically recogni-
sed by the Controller after the congu-
ration has been completed. To do this,
the Controller has to be in the same net-
work as the Chargers. The Controller can
be connected to an unlimited number of
Chargers.

You want to measure and visualise
your own PV production?
If you want to measure and visualise
your PV production, you must always
measure the current using a sensor on
one phase of your AC-PV inverter. For a
solar inverter, the arrow on the current
transformer should point from the in-
verter to the distribution board.
You have an AC battery storage sys-
tem that should be taken into ac-
count for the optimisation of the
power consumption?
Then use a current transformer to mea-
sure one phase of the battery storage.
This is only possible for AC battery sto-
rage systems. For an AC battery, the ar-
row on the current transformer should
point from the battery to the distributor.
Plug the jack plug of a current transfor-
mer into one of the inputs for current
measurement that are still free and mar-
ked "Sensor". You can assign them as you
wish. Clip the current transformer onto
one phase of the device or circuit whose
current ows you want to measure. With
3-phase devices that supply the same
power on all phases, measuring only
one phase is usually sucient. This is the
case, for example, with an AC inverter.
Again, please note that a current trans-
former may only be attached over one
phase, otherwise no measured values
can be recorded.
2.
After completing the basic installation,
you can use the remaining 3 to 5 current
transformers, depending on the type of
connection (single-phase or three-pha-
se), to measure the current ows of va-
rious devices or groups of consumers in
the building. This is suitable, for exam-
ple, for an AC PV inverter, an AC battery
storage system or large electrical consu-
mers such as boiler, air conditioning or
heat pump.
PV optimisation is also possible wit-
hout direct measurement of produc-
tion by the inverter.

Here you can use the slider to invert a load if
you have not connected a current transformer

In order for the power calculation to be correct,
the phase must be set correctly. Imagine that

6. Sensors
7. Sensors / Voltage settings
Under "Sensors" you can read the voltages,
currents and power in real time. L1 to L3
show the voltage of the phases connected
to the connecting clamp. I1 to I6 show the
values of the connected sensors (current
transformers). I corresponds here to the de-
signation Internal, which corresponds to
the connected sensor or also means load.
If you select L1, L2, L3 or N, you get to the volta-
ge settings of the phase.
Here you can see all the measured values of the
selected phase as well as the assigned loads
(internal/arom sensors). Just check whether the
voltage is approximately correct. If the current
and total power are not yet correct, this is not a
problem, because this conguration will be ex-
plained a little later.
Press the < button to return to the "Sensors"
overview.
connection, but without a voltage reference
we do not know whether we are feeding power
into the mains or drawing power from it.
Note that the power should always be positive
when drawing from the grid. With a solar in-
verter or an AC battery, the power should be
positive in feed-in operation, but if the batte-
ry is charged or the inverter has more standby
consumption than generation, the power may
be negative. If no power is being consumed, the
power should be close to zero.
It is very important that the correct phase
is set as the voltage reference. To nd out
which phase you have connected the sensor to,
trace the cables in the switch cabinet. Alterna-
tively, you can use a multimeter to check whet-
her the voltage at the go-e Controller matches
the fuse of the load.
The power factor can be between minus one
and plus one. Minus one means maximum
feed-in or charging for a battery without reac-
tive power, plus one means maximum draw or
production of energy. If the power is particular-
ly low, the power factor is not very meaningful.
For a pure ohmic load, the power factor should
be close to one.
To check the voltage allocation, you can sim-
ply switch on a large consumer with heating
elements in your household, e.g. a fan hea-
ter, a hairdryer or the electric cooker. If your
electric cooker is connected to a three-phase
system, checking is especially easy because
all phases are directly loaded with a power
factor of almost one. If the power factors are
incorrect and, for example, only plus or minus
9. Sensors / Load settings / Load
categories
After you have selected the "Categories" line in
the "Load settings" menu with the > key, you
will reach this submenu.
The go-e Controller does not know which sen-
sor you have mounted where. You set this with
the respective category.
s
There is the category Grid. This category is the
most important, because go-e Charger and go-e
Controller try to regulate it as much as possible
to zero during PV surplus charging.
one third or two thirds, you must adjust
the assignment. As long as the allocation
is not correct, your Controller cannot dis-
tinguish between feed-in and mains supply
and the PV surplus regulation will not work.
This submenu can also be used to dene the
load categories by navigating to "Categories"
and conrming with >.

2222 2323
Example 3:
If your solar inverter is connected to other loads
too far away from the control cabinet with the
go-e Controller, you cannot measure it directly.
As already mentioned, this does not matter for
PV surplus charging.
Below we explain 3 examples of how to congu-
re the categories.
Example 1:
If you have mounted the respective sensor
directly on one phase of the grid connection,
you should set the Grid category to one. If
you do not measure your household con-
sumption separately, you should also set the
Home category to one. This will allocate the
entire current of the measured line directly to
mains supply and household consumption.
If you have mounted a sensor on the line of a
PV inverter, you can assign the power directly to
the solar category. The power should be posi-
tive when the inverter is producing solar pow-
er. If you measure all phases in a single-phase
or three-phase inverter, choose a factor of 1.
However, if you have a three-phase inverter and
Example 2:
Let's assume we measure the load branch
and the inverter on all phases. Then the ca-
tegories correspond to the following picture:

PV
PV
onlymeasureonephase,youcanselectthefactor
3, the Controller then assumes 3 times the mea-
sured power, since we only measure one third.
We now have to assign the solar power to the
home category. Let's take a look at this calcula-
tion example:
• Grid: we draw 1 kW from the grid
• Solar: Solar: we generate 500 W of solar
energy
We have already allocated the 1 kW of grid con-
sumption to Home. However, since we produ-
ce another 500 W ourselves, the total power
we consume in the house is 1.5 kW. Therefo-
re, please also assign the solar inverter to the
Home category with the factor 1 or 3, depen-
ding on the number of measured phases of the
inverter.
We have to subtract the solar production from
thegrid, sowe haveto setthe factorto minusone.
If you simply measure a load, for example a
boiler, you can assign it to a custom category,
for example "Custom 1". You can rename the
category later. Assigning it to Grid or Home is
not necessary, as you are already measuring
these currents.

15. Settings / Network / WiFi, Ethernet, Hotspot
Enter the access data for your WiFi here or
congure your Ethernet (LAN) to ensure a con-
nection of the Controller to the network and to
go-e Chargers. This is absolutely necessary for
PV surplus charging or dynamic load balancing.
In addition, you can then connect to the Cont-
roller locally without the cloud via the go-e app.
Tip: The WiFi and Ethernet settings can perhaps
be made even more conveniently via the go-e
app.

20. Chargers / My Chargers
19. Main menu / Chargers
In order to display the go-e Chargers here, the
go-e Controller must be in the same network
as the go-e Chargers. As mentioned above, you
can congure the network in the main menu
under Settings. A list of all available Chargers
is displayed here. If a Charger is displayed with
"Paired", it is already communicating with the
Controller. If the Charger says "Found", it is not
ready to talk to the Controller. This may be be-
cause the automatic search for a Controller is
not activated in the settings of the go-e Charger
app for the corresponding Charger or the Char-
ger is already connected to another Controller.
This is because each Charger can only be con-
nected to exactly one Controller.
Now it's time to connect your go-e Controller to
one or more go-e Chargers.
Press the > key to select the "Chargers" menu
item. Than you can theoretically connect an in-
nite number of go-e Chargers.
16. Settings / Time
17. Settings / Cloud
Press the > key to select the menu item "Time".
Advanced users can synchronise the time via an
NTP server or the app. If the go-e Controller is
connected to the go-e Cloud via the Internet, it
always receives the current time from this. In
this case, no settings are required here. In the
time settings, the time zone can be set and the
automatic summer time changeover can be ac-
tivated.
For some functionalities and depending on the
go-e Charger you use, a cloud connection may
be required. Details can be found in the data
sheet of the go-e Controller.
Press the > button to select the "Cloud" menu
item.
18. Settings / Cloud
In this submenu you can activate and deacti-
vate the connection to the cloud. The current

This submenu allows you to connect to a MEC
meter and set categories for it.
You can also perform many of the described
conguration steps on the device via the app.
For certain functions, such as controlling ex-
cess charging or dynamic load balancing by
the individual Chargers, integration of the
Controller into the app is mandatory.
If you have already set up a go-e Charger, you
have to go back to the device overview by cli-
cking on the name or the device in the upper
left corner. If the go-e Controller was already
set up, you would see it in the device overview.
If you haven't set up the Controller yet, press
the plus in the upper right corner to set it up.
a) Use the "Initial setup for new go-e Control-
ler" if your Controller has never been set up in
a go-e app before.
b) If you have already connected your go-e Con-
troller to the home network directly on the dis-
play or with the go-e app, then select "Add an
already set up go-e Controller".

The "Initial setup for the new go-e Controller" is
similar to the initial setup of the go-e Charger.
You need to be near the go-e Control-
ler to perform the setup via the hotspot.
Note that you might need to disable mobile
data and terminate active WiFi connections on
some smartphones.

If you want to add an already set up go-e Cont-
roller, select "Add an already set up go-e Cont-
roller" and enter the serial number of the Con-
troller. You can also nd this on the data card
enclosed with the Controller. Then type in the
password. This is either the default password
on the data card or the one you entered during
the initial setup, and click "Connect".
Setup in app
On the home screen in the charging tab, you
can see the current power of each category.
The categories solar, grid, home and battery are
displayed here by default. Of course, the mat-
ching values are only displayed if the setup has
been performed for them.
If you have set up your own categories, you just
have to scroll down a bit and you will see them
as well.

To connect to the hotspot automatically, sim-
ply scan the QR code on the data card included
with the go-e Controller, or connect to the go-e
Controller manually in your phone's WiFi set-
tings using the hotspot password provided on
the go-e Controller data card. The process is si-
milar to the setup for the go-e Charger.

You can nd more details about the categories
and sensors in the menu item "Charging" under
the tab "Details".
Here, for example, all energy ows are shown
in a list view.
In the "Data" tab you can see diagrams of your
energy ows during the last hours. It is also
possible to export all data from the go-e Con-
troller and view it on the PC.
Start screen - Energy Flow - Details
In the "Settings" menu item of the app, you can
congure the sensors, assign them to catego-
ries and adjust them via the individual subme-
nu items, just like directly during the congura-
tion on the Controller itself. Time and display
settings can also be congured via the app.
Additionally, you can give the Controller an indi-
vidual name or change the password chosen by
you during the initial setup.
Important: If you have made the setup di-
rectly via the menu of the Controller, you
basically do not need to make any relevant
settings for the Controller here in the app.
You can jump directly to the end of chapter
10b of this manual.

If you select one of the internals I1 to I6 (loads)
in the "Sensors" view, you will get to the data
overview of the respective sensor/internal. In
the settings directly on the Controller, a similar
view can be found under the "Load settings".
Here you can invert a load via the slider, if you
have not connected a current transformer with
the arrows in current direction. Note that the
power should always be positive when drawing
from the grid. For a solar inverter or AC battery,
the power should be positive when feeding. Ho-
wever, if the battery is being charged or the in-
verter has a higher standby consumption than
it generates, the power may be negative. If no
power is being consumed, the power should be
close to 0.
If you want to adjust an assigned load catego-
ry or change the phase assignment, this is also
possible here in the overview of the respective
current sensor. This works similar to the menu
of the go-e Controller itself.
10b. Commissioning/operation via app
As on the Controller itself, you can congure
the voltage and current sensors in the menu
item "Settings", submenu "Sensors" and read
their voltages, currents and powers in real time
after selecting them. You can also do this direct-
ly on the go-e Controller.
Voltage sensors L1 to L3 always measure the
voltage of the connected phases and current
sensors Internal 1 to Internal 6 measure the
current and power. To ensure that the power
calculation by the go-e Controller is really cor-
rect and that functionalities such as PV surplus
charging and dynamic load balancing work pro-
perly, you need to make sure that you have set
the correct voltage reference for all phases and
that the correct categories and power factors
are stored. What exactly has to be observed is
explained in this manual in chapter "10a. Com-
missioning/operation on the device" using vari-
ous examples. Below, we will only explain whe-
re you can nd which settings in the app.
Settings / Sensors / Sen-
sors Configuration
If you select one of the voltage sensors, e.g. vol-
tage sensor L1, you will see all measured values
of the selected phase.
If you have connected one or more phases of
the power supply incorrectly, you could also
change the voltage phase assignments here by
pressing "Assigned Phase".

Categories
If you tap on "Categories" in the "Settings"
menu, you will get to the sensor conguration
view. Here you can select individual categories
and then assign the selected category to the
various connected sensors. So this is an alter-
native way to link loads and sensors.
Settings / Categories
If you select one of the categories, you can
enter a number for the factor with which this
category is to be considered by the respective
current sensor directly behind the name of the
respective internals (current sensors). Please
note the previous remarks in the manual. If you
have already entered factors via the Controller
menu or via the "Sensor conguration" setting,
you will already see numbers here.
For custom categories, you can even change
the name of the category, for example, to boiler
if you measure it with a sensor.
Please note here as everywhere in the app: You
have to save changes by tapping the disk icon in
the upper right corner.
Settings / Categories
Category details
Settings / Controller Time Settings
In this submenu you select which category the selec-
ted load, in our case Internal 1, should be assigned to.
Simply enter a number behind the respective catego-
ry for the factor with which this current load is to be
considered.
For example, if you measure your mains connection
with a sensor, you should assign the factor 1 to this
load in the category "Grid". If you do not have a sepa-
rate sensor on the load branch, in other words the rest
of your household, you should also assign the "Home"
category with a factor of 1.
If you measure the current of a three-phase AC PV
system with only one sensor on one phase, you must
set the factor for the "Solar" category to 3 for the cor-
responding sensor so that the total power of the PV
system can be displayed correctly. This works here be-
cause a three-phase inverter delivers the same power
on all phases. So you save two sensor connections for
other purposes.
Advanced users can synchronize the time via an
NTP server or the app. If the go-e Controller is
connected to the go-e Cloud via the Internet, it
always receives the current time through this.
In this case, no settings are required here.
In the time settings, the time zone can be set
and the automatic summer time changeover
can be activated.
