Sustainable charging
Electric vehicles also need energy, which
has to be generated. If we use the availa-
ble energy carefully, we will not need to
expand fossil fuel power plants or nucle-
ar power plants for electric mobility.
An important contribution we can all
make is to use surplus energy. So if pos-
sible, do not charge your car when you
come home after work, as this is the
time when the electricity grid is at its
peak anyway. In order to save energy
and thus also to charge in an environ-
mentally conscious way, you should, if
possible, postpone your charging with
the go-e Charger „Scheduler“ function to
Even more interesting could be an elec-
tricity contract with a provider oering
exible energy taris, where you can
benet from the highly uctuating elec-
tricity prices quoted at the electricity
price exchange. With the go-e Charger,
you only charge when the electricity
is cheapest.
The technology for this is already in-
tegrated in each of our charging sta-
tions. All you need to do is sign a
contract with an electricity provider
whose exible electricity tari is in-
tegrated in the go-e app. Several 100
taris are available. The number of
taris is constantly being expanded.
By the way, in combination with the
go-e Controller (separate product)
you can easily charge with photovol-
taic surplus power. Due to the open
interfaces of our chargers, this also
works with other energy management
systems.
We wish you lots of fun with your go-e
Charger and enough electricity at all
times.
Your
With the go-e Charger Gemini you have
chosen an extremely compact and ver-
satile charging station for electric vehic-
les. Smart and intelligent solutions that
make charging electric cars even more
convenient are already integrated in the
go-e Charger Gemini.
Compared to the classic wall charging
station, the go-e Charger Gemini can be
installed more quickly by an electrician
and easily connected to an existing junc-
tion box where applicable.
The go-e Charger was developed and
tested by electric car drivers for electric
car drivers. To ensure that it remains up-
to-date in the future, we are constantly
developing the rmware and adapting
the app to the state of the art. So let us
surprise you with future functions.

Disposal
The Charger should not be operated in
the immediate vicinity of ammable or
explosive substances, running water or
heat-emitting equipment.
The go-e Charger must be mounted ver-
tically in the wall bracket on a at wall.
Make sure that the power connection
leading to the go-e Charger is properly
installed and undamaged.
The go-e Charger is equipped with a
DC protection module that protects the
building installation from possible DC
faults that could be caused by an electric
car. On the building side, an RCD type A
and a miniature circuit breaker must be
installed. The go-e Charger also provides
additional protection against AC faults (6
mA DC, 20 mA AC). The local installation
regulations must be observed.
The go-e Charger may only be operated
at fully functional protective devices.
Connection cables must be suciently
dimensioned.
An electric shock can be fatal. Do not
reach into sockets and plug systems by
hand or with technical aids.
The go-e Charger has a safety function
called „ground check“, which prevents
charging in TT/TN power grids (com-
mon in most European countries) if the
power connection is not grounded. This
function is activated by default. It may
only be deactivated via the go-e Charger
app if you are sure that the power grid
does not have an earth connection (IT
grid, e.g. in many regions of Norway) so
that charging can also take place here.
The go-e Charger visualises a deactiva-
ted „ ground check“ by 4 red LEDs (3, 6,
9, 12 o‘clock).

Make sure that the surface is not warped. The device
may not be attached if the wall bracket is distorted.
Compensate possible unevenness of the wall with
spacers (not included in the scope of delivery). 6. The go-e Charger Gemini may be connected single-
phase and three-phase. If necessary, lay an additional
supply line. When selecting the cable cross-section,
observe the simultaneity factor and the type of in-
stallation. We recommend the following cable cross-
sections, but the electrician has to decide according
to local conditions:

3. Starting the charging process
Connect the go-e Charger and the vehicle by using a
type 2 charging cable (or if the car has a type one so-
cket by using a type 2 to type 1 adapter cable). Make
sure that the type 2 plug is inserted as far as possible
into the type 2 socket of the charger.
The Charger is ready for charging and is waiting for
the car to release it. The LEDs light up yellow in the
number of the preset charging current.
2. Ready to charge
The go-e Charger is ready for operation. The number
of blue LEDs corresponds to the set charging current.
Five predened charging levels can be selected via
the button.
You can adjust the charging levels individually in the
go-e Charger app („Current levels“). It does not mat-
ter whether the go-e Charger is connected single-
phase or three-phase.
1 LED = 1 A
Gemin 11 kW = 6 A - 16 A
Gemini 22 kW = 6 A - 32 A
1. Start of the charger
The go-e Charger performs a self-test during initial
start-up or after a restart, during which the LEDs light
up in rainbow colours.

7.
When installing several devices, connect the
phases of the rst, second and third charger to the
domestic circuit in rotation according to the adjacent
illustration to ensure even load distribution when
charging single-phase vehicles.
Activate static load balancing via the go-e Charger
app (WiFi required).
When using the go-e Controller, you can activate
dynamic load balancing, which takes into account the
electricity consumption in the entire house.
If your energy provider prescribes a ripple control
receiver, the two data cables (white and red) are
also needed to be installed.Polarity order does not
matter.

9. Commissioning/charging
5. Stop charging
The charging process is completed when the LEDs
light up green.
If you want to stop charging prematurely, use the
„cable release“ function of your vehicle or the large
round button of the go-e Charger app (tab „Char-
ging“).
The cable remains locked in the type 2 socket in the
standard setting after the charging process has en-
ded (adjustable via the app) until it is removed from
the vehicle (theft protection).
If the power supply is interrupted, the charging ca-
ble remains locked in the charging box for reasons
of theft protection. To unlock it, it is necessary to re-
energise the charging station. The cable can also be
unlocked automatically after a power failure, provi-
ded the function has been activated in advance via
the „Cable unlock“ setting in the app. However, it is
then no longer theft-protected in the event of a pow-
er failure.
4. Charging
After the car has enabled charging, the LEDs rotate
clockwise around the type 2 socket during the char-
ging process.
The number of „tails“ corresponds to the number of
connected phases or the number of phases set in the
app:
•1 rotating tail = 1-phase charging (230 V)
•3 rotating tails = 3-phase charging (400 V)
The speed of rotation and length of the tails indicate
the amount of charging current.
The go-e Charger displays the charging status via dif-
ferent colours and positions of the LEDs. In addition,
it executes a whole series of safety queries to check
the used power source for possible errors. For this
reason, the go-e Charger may display an error and
refuse to charge, especially with unknown power
sources.
The device visualises the cause of the error by certain
colours and positions of the LEDs. You can also nd
the error message within the „Status“ information of
the app. (The following colour codes correspond to
the factory setting).
Ground check deactivatedGround check deactivated
4 LEDs light up red (3, 6, 9 and 12 o‘clock).
The go-e Charger has the safety function „ground
check“, which prevents the charging process in TT/
TN power grids (common in most European count-
ries) in case of insucient grounding of the pow-
er connection. This function is enabled by default
and can be disabled via the go-e Charger app.
However, the „Ground check“ should only be disa-
bled if you are sure that the electricity grid has no
grounding (IT grid, e.g. in many regions of Norway),
so that charging can also be carried out here. If you
are not sure, you must leave the setting in the app at
„Enabled“!
WaitingWaiting
The LEDs ash blue in the number of preset charging
power.
The go-e Charger waits to charge based on a preset
sheduler or to obtain cheap electricity when charging
with a exible electricity tari.

10. LED status display/troubleshooting
Fault current detected
The LEDs ash red at the top and light up pink at the
bottom.
The Charger has detected a DC fault current >= 6 mA
or AC fault current >= 20 mA. To acknowledge the
fault, press „Reboot“ in the app or disconnect the
Charger from the power supply for a short time. If
necessary, the charging current can be reduced, but
also check the connection used. (The charging system
in your vehicle may also be defective).

at the top.
The temperature in the go-e Charger is increased.
Therefore, the charging current is automatically re-
duced.
Phase error
The LEDs light up blue at the bottom and ash red at
the top.
Check whether the phase/s of the go-e Charger are
connected properly. It is possible that only 2 phases
are connected. If no function occurs, contact the go-e
Support.
Error unlocking or locking
The LEDs briey light up red at the top and yellow at
the bottom.
The charging cable could not be unlocked or locked
properly. The unit tries to repeat the process every
ve seconds. The type 2 plug may not be inserted
completely. Try to insert it into the type 2 socket as
far as possible.

11. Reset card/RFID chip
Reset to factory settings
You can also use the reset card to reset the
go-e Charger to factory settings:
•Hold the reset card in front of the chargers RFID
reader
• All LEDs light up red briey to conrm
The stored RFID chips and assigned consump-
tion data are not deleted during this process.
go-e Charger reset card
On the back of the reset card you will find important
access data which you need to set up the app control
of the charger:
•“Serial number“: Serial number of the go-e Charger
• “Hotspot SSID“: WiFi hotspot name of the charger
• “Hotspot key“: WiFi hotspot password of the device
• “QR-Code“: Automatically connection to the hotspot
RFID chip
Protection against unauthorised charging
If you install the go-e Charger outdoors, you can
protect the device against use by unauthorised
persons by means of an RFID chip. In the settings of
the go-e Charger app, „Authentication required“ or
„RFID/App required“ needs to be selected for this.
The delivered RFID chip is already learned.
To authenticate a person authorised for charging,
the chip needs to be held in front of the RFID reader
(below logo of the charger) before each charging
process. Alternatively, authentication can be done by
tapping the round button of the tab „Charging“ of the
go-e Charger app.
Ideally, leave the reset card at a secure location where
you can quickly access it in case you need it.

11. Reset card/RFID chip
Consumption overview for several users
Furthermore, additional user accounts can be created
with additional RFID chips (available as accessories).
This is useful if several people share the unit and the
charged current should be displayed separately for
each user in the app.
Additional RFID chips can be learned via the app
(„Settings“/“RFID chips“). Simply select one of the free
slots and follow the instructions in the app. The chips
can be renamed individually in the app.
Any RFID chip/card that transmits on a frequency
of 13.56 MHz (e.g. also many credit cards) can be
learned.
12. App - connection setup
The go-e Charger can also be used without an app.
Download the go-e Charger app if you want to change
basic settings, use comfort functions, read the inter-
nal electricity meter or control the charger remotely.
The go-e Charger app is available for download on
the platforms listed opposite, depending on the ope-
rating system of your mobile device.
Set up connection via hotspot
1. Some smartphones require deactivating mobile
data and terminating active WiFi connections.
2. Either scan the QR code of the reset card (an ex-
ternal app may be required for this) or manually
search for the charger‘s network (displayed as
go-e-xxxxxx) in the settings of your mobile device
to connect to the charger‘s hotspot. If you con-
nect manually, you need to enter the password
that you will nd on the reset card under „Hot-
spot key“.
3. Now launch the go-e Charger app.
4. If the „Charging“ page is already displayed, you
can already operate the charger locally via the
app. Otherwise, you need to select your go-e
Charger in the app beforehand.

Set up connection via WiFi
For remote control of the charger and for some com-
fort functions, a WiFi connection of the charger is es-
sential.
1. To connect to the WiFi network, you have to esta-
blish an active hotspot connection to the Charger
(as described above).
2. Then tap the „+“ icon in the app.
3. On the following screen, select „Initial setup for
new go-e Charger“. As soon as the hotspot con-
nection has been detected, tap on „Next“. On the
next screen, the connection to WiFi needs to be
activated.
4. Enter the name of your WiFi („SSID“) or select
your WiFi (if displayed). You also need to enter
the „password“ of this WiFi network. As soon as
the connection has been established, a „Next“
button appears, which you have to tap. Follow
the subsequent instructions of the app until the
„Done“ button appears. Tap this button.
5. Check whether the connection to the go-e Cloud
is allowed under „Advanced settings“ (in the „In-
ternet“ tab of the go-e Charger app).
6. Disconnect the hotspot connection to the Char-
ger, establish a smartphone internet connection
to control the Charger remotely via mobile data
or WiFi.
The „Charging“ tab of the go-e Charger app gives you
direct access to the most important functions for
starting, stopping and monitoring charging proces-
ses.
Do you have several go-e Chargers? Tap the picture
of the Charger or its name to go to the selection page
with the list of available devices. Select the Charger
you want to operate.
Tap the „+“ icon at the top right to connect a new or
existing go-e Charger to the app.
Use the 3 tabs to switch between the screens „ Pow-
er“, „Details“ and „Data“.
The tab „Power“ shows the current charging power
in the large circle (if charging is in progress). You can
start and stop the charging process by tapping this
circle. In this case, you are charging in standard char-
ging mode, which does not take into account e.g. e-
xible energy taris.
Use the 3 round icons below to access the settings for
„Mode“, „Current“ and „Planned charge“.
You are also able to change the charging current du-
ring the charging process via the „Current“ icon, even
in steps of 1 ampere using the slider.
Under the headings „Status“, „Energy“ and „Informa-
tion“ you will nd further details regarding the char-
ging process.
If you tap „Energy per user“, a list with the charged
electricity quantities of all learned RFID chips is di-
splayed. You can also download the charging history
or meter readings here.
Use the 3 tabs to switch between the screens „Char-
ging“, „Settings“ and „Internet“.

Photovoltaic surplus charging
Basically, the go-e Charger allows you to charge your
car easily and automatically with surplus electricity
from your photovoltaic system (PV). However, this
requires an energy management system (EMS). The
go-e Controller (separate product) is an example of
such an EMS . The open interfaces of the go-e Charger
also allow you to use other EMS. For these, however,
you usually need to have programming knowledge
or check in advance whether the EMS you want
to use already has the go-e Charger integrated.
12. App - settings 12. App - settings
You can adjust the basic and comfort settings of the
charger via the „Settings“ tab of the app. You are pro-
vided with help notes in the app for the setting opti-
ons, which is why you will only nd basic information
below.
Current levels
When delivered, the black button of the go-e Charger
is predened with 5 amperage levels for selecting the
charging current. You can switch between the levels
step by step by pressing the button. You are able to
adjust the current intensity of the ve levels to your
personal needs via the „Current levels“ setting option
of the go-e Charger app.
With lower amperages, you charge more sustainably,
which can have a positive eect on the stability of
the power grid. With high amperages, you charge the
battery faster.
Save energy with kWh limit
The „kWh Limit“ function is practical if you do not
want to fully charge the battery because, for exam-
ple, you live on a mountain and want to recuperate
when driving downhill. Set in the „kWh Limit“ menu
how much energy should be charged until the next
trip.
Flexible energy taris - charge cheaper
If you have a contract with your electricity provider
about a exible electricity tari with changing taris
every hour or at certain times of a day, you can con-
gure the Charger so that it charges your car at the
cheapest hours. To do this, we have integrated exib-
le energy taris in the app to provide you with a sus-
tainable and money-saving way of charging. The list
of energy providers you can see in the go-e Charger
app is constantly expanding, as dynamic electricity
pricing is a relatively new concept. Check in the go-e
app under „Mode“ whether your energy tari is al-
ready integrated. Select the country you live in, your
energy provider and the tari you have signed up for
with your energy provider. Then activate „ECO Mode“
or „Next Trip Mode“ under Mode and set a price, time
or kWh limit at which the go-e Charger should start or
nish charging for the selected charging mode in the
„Settings“ tab.
In „ECO mode“, you can set a price limit per kWh. As
soon as the electricity price falls below the threshold
you set, the wallbox charges your electric car.
In „Next Trip Mode“, you can set a time and a kWh
amount to charge your vehicle without a price limit.
The go-e Charger automatically selects the cheapest
hours for charging according to your electricity tari
until the specied kWh amount is reached within the
set time limit. If you wish, you can continue charging
in ECO mode by manually setting the charging price
limit.
A cloud connection (WiFi) is required for this functio-
nality. The current prices are automatically transfer-
red to the charger and displayed in the „Data“ tab on
the „Charging“ screen.

Load balancing
If you operate several go-e Chargers at one po-
wer connection, you should use the „load balan-
cing“ (static) function so that the building power
connection is not overloaded. A cloud connec-
tion (WiFi) is required for this function. If the
cloud connection is temporarily interrupted, the
go-e Charger will continue charging with redu-
ced charging current in fallback mode, provided
a charging current value greater than 0 A has
been entered for this purpose. When using the
go-e Controller, you can activate dynamic load
balancing, which takes into account the electri-
city consumption in the entire house.
12. App - settings 12. App - settings
Scheduler
The „Scheduler“ option allows you to postpone
the charging process to a time when electricity
is available in abundance (often at night). In this
way, you act in a particularly sustainable way,
as you do not increase the load peaks that are
common at the end of the working day and take
electricity that could otherwise not be used sen-
sibly. In this way, you ensure grid stability.
After activating the scheduler, you can dene
when the go-e Charger may charge or not char-
ge. For weekdays, Saturday and Sunday, 2 time
periods can be dened separately.
Cable unlock functions
The default setting under „Cable unlock“ is that
the charging cable should remain locked in the
charger after the charging process until it is re-
leased at the vehicle (theft protection). Alternati-
vely, you can lock the cable permanently. This is
useful if you rarely take it with you in the car and
the go-e Charger has been installed outdoors.
The function serves as a permanent protection
against theft of the cable. Furthermore, you can
have the cable automatically unlocked after
the charging process. This is convenient if you
share the charging station with several people
and want to allow them to use the charger at
the end of your charging session.
Combine cheap electricity taris and
photovoltaic surplus charging
In combination with the Controller, you can even
combine charging with PV surplus and favoura-
ble electricity taris in „Eco Mode“ and „Next Trip
Mode“. The Charger rst tries to use as much so-
lar power as possible and then continues charging
with cheap electricity rates.
For charging with PV surplus power with go-e
Charger and go-e Controller, customisations
have to be made in the app under „Settings“ in
„ECO Mode“ or „Next Trip Mode“. There you will
nd a slider „Charge with PV surplus“, which you
need to activate. You can then adjust the exact
settings via the link „PV surplus“ below the sli-
der. Here you can also opt for automatic pha-
se switching in order to be able to charge even
when the PV system‘s output is low. Afterwards,
you need to activate the respective mode in the
„Charging“ tab. How charging works in conjunc-
tion with the go-e Controller is explained in de-
tail in its instructions.

1. go-e GmbH grants a guarantee for go-e chargers of the Gemini series against material and func-
tional defects in accordance with the following conditions. The warranty period is 36 months from
receipt of the goods after the rst purchase of the product from go-e or a reseller. This warranty
is in addition to the statutory warranty of 2 years (from receipt of the goods) and does not limit it.
2. The guarantee is only valid on presentation of proof of purchase stating the date of purchase.
3. In the event of a guarantee claim, the customer has to inform go-e GmbH immediately in text
form to complain about the defect. In the event of a justied notice of defect, go-e is obli¬ged
to improve or replace the goods as soon as possible or to arrange this. In the (justied) case of
the return of the defective product to go-e, go-e will bear the costs incurred. If, in the event of a
guarantee claim, it becomes apparent that the device needs to be replaced, the customer waives
ownership of the previous device from the date of return shipment and the new device simulta-
neously becomes the property of the buyer. This transfer of ownership also applies if, as a gesture
of goodwill, a device is replaced outside the guarantee period at reduced conditions. If a defect
that is justiably notied within the guarantee peri¬od concerns a permanently installed charging
station, go-e GmbH will send the customer a replacement box and will pay a total of up to 70 euros
of the electrician’s costs incurred in uninstalling the defective charging station and installing the
replacement unit. In any case, evidence in the form of an invoice has to be provided. For safety
reasons, the disassembly of an allegedly defective, permanently installed go-e product may only be
carried out by a qualied electrician. Before dismantling the product, always contact go-e’s techni-
cal custo¬mer support and wait for its decision on the further procedure for handling the service
case. Repairs may only be carried out by the manufacturer go-e. For repairs not carried out by go-e,
there shall be no claim to reimbursement of costs under the guarantee.
4. In the event of incorrect storage, use or installation/mounting by the buyer/installer and resul-
ting damage to the product or other technical defects caused by the buyer/installer, the guarantee
and statutory warranty shall expire. In this case the buyer bears the shipping costs. This applies
especially if the product is not operated with a special original adapter manufactured by go-e
GmbH or is used for other purposes than those specied by the manufacturer.
5. The guarantee and warranty also expires in the event of any modication or opening of a go-e
product or if there is no proof of installation by a qualied professional. (e.g. commissioning cer-
ticate)
6. go-e GmbH shall make every reasonable eort to provide the operation of all free digital sup-
plementary services in accordance with the representations in the operating instruc¬tions of the
products, including but not limited to app and cloud functions. go-e does not, however, guarantee
that these will always function error-free, fully available and without interruption. go-e GmbH does
not provide any guarantee, warranty or assurance for these digital ad¬ditional functions, but will
endeavor to provide a workaround or update to rectify errors or eliminate faults free of charge
within a reasonable period of time following an error/fault report by the customer. The customer’s
report can be made by telephone during go-e business hours, by e-mail to o[email protected] or
by using the contact form on the go-e web¬site. go-e shall be entitled to apply restrictions for the
elimination of errors/malfunctions and/or workarounds, as well as to postpone the elimination of
errors/malfunctions until the release of an update. In order to full this obligation, go-e GmbH is
entitled to suspend the digital supplementary services due to planned or unplanned maintenance
work, which is why go-e does not guarantee that the digital services will be available without res-
triction at any given time.
7. Claims arising from this guarantee shall be governed exclusively by Austrian law, excluding the
conict of laws provisions, in particular the UN Convention on Contracts for the International Sale
of Goods.
