Questions & Answer

Our chargers are able to charge all models of battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV) of all car brands.

Whether or not to obtain permission to use the go-e Charger depends on the country's regulations. It may also depend on which go-e Charger model you intend to use. Please contact your local electricity network operator in advance to find out whether the charger requires registration or approval. 

• The go-e Charger offers an exceptional price-performance ratio, consistently securing top positions in various wallbox tests.
• It comes with an intuitive app that allows you to adjust various settings and fully control the charging process remotely.
• go-e Chargers provide numerous functions that enable you to charge even more sustainably and financially advantageously. Of course, you can also charge your car with the go-e charging station without enabling the features — just like with a smartphone charger.
• You can take our mobile wallboxes with you when travelling or camping.

You can only charge a car’s battery at the maximum charge rate the car can accept. So if your EV’s charging speed is 11 kW or lower, the go-e Charger 11 kW is a good choice. If it’s higher, opt for the go-e Charger 22 kW to enjoy faster charging.
For vehicles that can only charge using single-phase power but require more than 16 amps, a 22 kW wallbox is recommended. Generally, this allows charging at up to 4.6 kW (20 amps), and in exceptional cases, up to 7.4 kW.
Note: The go-e Charger 22 kW offers the option of higher output in a single-phase connected situation, allowing you to operate it at 11 kW now while being ready for faster charging in the future if your electrical system supports it.

The main difference between the two types of chargers is that Gemini flex (incl. 2.0 version) is a wallbox that offers portability, while Gemini (incl. 2.0 version) is stationary. The first one allows you to take the charger with you wherever you go, whereas with the second one, you are more likely in most countries to receive subsidies. 

The go-e Controller enables simple control of charging with surplus electricity from the PV system, dynamic load management and the avoidance of load peaks.

The go-e Controller measures power flows in the building and controls an unlimited number of go-e Chargers in such a way that, with the appropriate configuration, they charge without drawing power from the grid (only charging with excess PV power). However, charging with surplus electricity is also possible while simultaneously using electricity from the grid. On top of that, the Controller adjusts the charging power of each go-e Charger depending on the available electricity in your building. In scenarios where high energy consumption might exceed the available power, the Controller automatically reduces the charging power of specified chargers, ensuring that you avoid blackouts and power shortages.

For this purpose, the go-e Controller transmits the power values of the entire system, including battery storage (if included in the measurement), to all connected go-e Chargers.

The go-e Controller is used to record measured values in an electrical distribution system and make them available in a network.

• Photovoltaic surplus charging for self-consumption optimisation (charging with surplus energy from the PV system that would otherwise be fed into the public grid).
• Dynamic load management (consumption of various appliances in the house (e.g. hair dryer, kettle, oven) is taken into account when regulating the charging power, so that the charging power is automatically reduced, for example)
• Energy monitoring & peak shaving (ensures that certain energy peaks in power consumption are not exceeded)
• Open API & interface to the go-e Charger

The go-e Controller is compatible with all types of PV inverters as well as AC battery storage systems. PV-optimisation is also possible without direct measurement of production by the inverter. Own production can be measured and visualised via a sensor for AC inverters only. Communication with the inverter or the battery is not necessary. However, for hybrid inverters with direct DC battery connection, separate measurement of battery and PV production is not possible. Furthermore, compatibility with all go-e Chargers and the go-e app is also given.

You can reset the go-e Charger with the white reset card included in the delivery. To do this, simply hold the reset card against the RFID reader located on the front of the go-e Charger (by the go-e logo) and wait until all the LEDs light up red.

You can choose the charging mode in the Charger tab by clicking Eco, Basic or Daily Trip.

The go-e Charger PRO series offers Ethernet. All go-e Charger models offer WiFi.

The go-e Charger PRO series comes with a permanently attached type 2 cable. 

The go-e Charger is suitable for charging all electric vehicles with a type 2 plug. The vehicles with type 1 plugs can also be charged with the go-e Charger via a type 1 to type 2 adapter or cable.

Plug&Play allows you to use the go-e Charger Gemini flex (2.0) immediately after plugging in.

The go-e Charger Gemini(2.0) can be used right after it gets installed by a qualified electrician.

If you have the go-e Charger Gemini flex (2.0), you need to plug it into a socket and connect it to your car with a type 2 cable. If you have the go-e Charger Gemini (2.0), you can start using it after the wallbox has been installed by an electrician. Simply plug the type 2 cable into the car and the charger and charging will start automatically (default settings).

You can change this setting via the app, which means that the charging process will not start until you unlock the charger via the app or RFID chip.

The charging process ends automatically when the car's batteries are charged or an event defined by you via the app occurs. You can also stop charging prematurely either via the app (“Charging” tab) or by simply unplugging the charging cable on the vehicle side.

Please do not disconnect the mobile go-e Charger from the power supply during charging. 

The charging power can be set either by the button at the device (5 predefined values) or via the app. The button values can be set as desired in the app in the range of 6 to 16 or 32 amperes (depending on the maximum charging capacity of the charger - 11 or 22 kW). If you want to change the charging power during the charging process, you need to use the app.

You cannot deactivate the LEDs of the go-e Charger during the charging process. Nevertheless, the LEDs can be switched off after 10 seconds in standby mode. Their brightness can be adjusted in the app.

The go-e Chargers of the Gemini series are delivered with a U-piece, which you can attach to the wall directly above the charger. This means the wallbox can no longer be removed from the wall bracket. In addition, a padlock can be attached (not part of the scope of delivery).

The charging cable that connects the wallbox and vehicle is locked during the charging process and in default mode after charging is finished. This ensures that no one can use it until you unlock the cable. You can change these settings in the app.

From our experience, charging capacity has a barely noticeable effect on battery ageing, especially when charging with alternating current. Many claims circulating online are based on outdated battery technology and low battery capacity.

The so-called C-rate is a good reference point for charging capacity, which is gentle on the battery. It describes the relationship between charging current and battery capacity. Suppose you charge your car with 22 kW of current, and the battery has a capacity of 22 kWh. Then C = 1. If the battery capacity is halved and the charging current remains the same, then C = 2. The higher the C value, the greater the effect of the charging process on the life of the battery. However, this can only be determined with very high mileage. When C = 1, the reduction in battery life is barely noticeable.

To remove the go-e Charger from the wall mount, slightly lift it up and pull it towards you. By the way, you can remove both the go-e Charger Gemini flex and the go-e Charger Gemini (incl. 2.0 version) from the wall mount. This allows you to read the serial number of your charger without the app. You can find it on the serial sticker on the back of the wallbox. However, only the go-e Charger Gemini flex (2.0) or its predecessor, the go-eCharger HOME+, can be used on the move.

There are two approaches to throttling the charging power on a go-e Charger Gemini (flex):

• go-e Charger Gemini 2.0 (stationary version, without CEE plug):

The go-e Charger Gemini (2.0) offers the option of software-only throttling and also an additional option via hardware (data cable).
For software throttling, select the Settings tab. Now click Security -> Network -> Maximum charging current and enter the desired value. For a throttling of 22 kW to 11 kW, you must enter the value 16 A here.
To ensure that the settings are not freely accessible, it is necessary to protect them with the technician password. To do this, go back to the Security window and select Password -> Technician password settings. If you have not yet set the technician password, now is the right time to do so.
Once you have created a technician password, activate the Password protection network requirements option.

Throttling for grid-friendly control via data cable

If you also want to throttle the go-e Charger Gemini (2.0) via hardware or, for example, only want to activate a temporary limitation for grid-friendly control, you can do this via the two data cables.
For throttling, you can bridge the two data cables, for example (freely selectable). When connecting to a ripple control receiver, it is of course important to note whether the cables are "closed" or "open" in the event of a limitation.
To configure what should happen here, go to the Settings tab. Now click on Security -> Digital input, activate the digital input and specify what should happen here.
If the power is only to be reduced, select Allow charging and set the maximum charging current. However, if charging is to be interrupted, then Allow charging must not be activated.
Finally, define the normal state of the two data cables, i.e. the state in which there is no throttling/limiting.
This option should also be protected with the technician password (the digital input password protection, see above).

• go-e Charger Gemini flex (2.0) (mobile version, with CEE plug):

The go-e Charger Gemini flex (2.0) offers the option of software throttling. For software throttling, select the Settings tab. Now click Security -> Network -> Maximum charging current and enter the desired value. For a throttling of 22 kW to 11 kW, you must enter the value 16 A here.
To ensure that the settings are not freely accessible, it is necessary to protect them with the technician password. To do this, go back to the Security window and select Password -> Technician password settings. If you have not yet set the technician password, now is the right time to do so.
Once you have created a technician password, activate the Password protection network requirements option.

Setting the charging power of the go-e Charger is very simple.
You have two options:

Option #1 (only for Gemini (2.0) series): Change the charging current directly on the go-e Charger by pressing the physical button briefly. The number of LEDs changes immediately. One LED stands for one ampere. The LEDs therefore indicate which charging level you have selected. By the way, the charging levels are in ascending order. So if you want to go back — for example, from 10 amps to 6 amps — just keep pressing the button until you reach 6 LEDs again, i.e., 6 amps. Be careful, because the push-button only works before you start charging. During charging, the button is deactivated.

Option #2: Set the charging power in the go-e app. To do this, simply click on the “Charging speed” field in the “Charger” tab, where you can change the charging current and the phases. You can even do this in 1-ampere steps using the slider.

If your electric car allows not only single-phase but also three-phase charging, the go-e Charger will automatically charge three-phase if possible, desired, or necessary.

You can use our free app to check the number of kWh charged, adjust the current, configure many additional features and even control the charging process remotely. Cars can also be charged without an app in the default setting.

Yes. All the main functions, such as start/stop charging and adjusting the charging current, can be done without the go-e app. 
If you want to change basic device settings, use the comfort functions, read the internal electricity meter or control the charger remotely, you need the go-e app. You will then be able to control the wallbox from close range via the built-in access point. To remotely control the charger, you need to connect the device to your WiFi network.

No, as the app can also be used via the access point built into the wallbox. Only the remote control and some functions such as flexible electricity tariffs or load balancing, are not possible without WiFi.
For advanced connectivity, the go-e Charger Gemini 2.0 and PRO series include cellular connectivity, allowing app control even without WiFi. Additionally, the go-e Charger PRO offers an Ethernet (LAN) option for a reliable wired connection.

To do this, simply download the go-e app for your smartphone and open the app, Click on “Add go-e device” and then enter the serial number, which you will find on the reset card, and the password you have assigned to the go-e Charger. Confirm the terms of use and the wallbox will be added to the app.

To export the charging data of your go-e Charger, open the go-e app and click on the “Information” tab. There you will see the charging status, the amount of energy and other information. Now scroll down a little and click on ‘Download information’ to export the charging data as a csv file. 

In the app, you can view the amount of electricity charged during a charging process as well as the total amount of kWh charged. This information is available in the app under the “Charger” menu item. In addition, the charging energy for all user accounts (maximum 10 RFID chips) can be displayed. You can also download a detailed charging history.

The new go-e app is available to all go-e Charger users and is automatically updated for everyone. You can learn more about this version here.
The classic go-e app (older version) is intended for users of the go-e Charger HOME series (hardware version V2). You can learn more about this version here.

If you have forgotten your go-e Charger password, it is first of all important to understand which password you have forgotten. There are the following passwords:

• Technician password
• Hotspot password
• Cloud access password

Have you forgotten the technician password?
The go-e Charger must be online so that we can reset it via API Debug. There is no other way to reset this password.
Have you forgotten your hotspot password?
Reset the go-e Charger to factory settings and restart it.
Have you forgotten your cloud access password?
In the go-e app, go to "Security" in the Settings tab and then to "Password".

First check the go-e website for any hints on how to solve the error, e.g. in the FAQ, and then contact go-e support if necessary.

No. The controller must be connected to the WLAN via its menu or via the app.

In addition to numerous local interfaces such as HTTP API, Modbus TCP and MQTT, there is also an optionally usable cloud connection to the go-e Cloud, which is, however, not required for the PV surplus charging and dynamic load management functions.

There is an HTTP REST API that can be used via a local WiFi connection. The API is an open interface that allows other intelligent devices to communicate with the charger. In addition, the go-e Charger supports OCPP, enabling integration with third-party backend systems for advanced management and monitoring. The Modbus TCP API is integrated into the go-e Charger as well. Like the go-e network operator API, it provides authorised access to the go-e Charger by the electricity network operator to control the power supply to the grid.

Yes, PV surplus charging is possible with the go-e Charger.

• Using the go-e Controller:

The go-e Controller monitors your home’s energy usage and automatically starts charging your car when there is excess solar power. It intelligently adjusts between one- and three-phase charging based on your solar panel output once you configure your preferences in the go-e app.

• Via integrations with partner systems:

You can use integrations from partner brands such as Clever-PV and Solar Manager for PV surplus charging. They already have go-e Chargers integrated into their systems, which makes setting up solar surplus charging fast and easy. Note that some integrations use the OCPP protocol instead of go-e’s API.

• With an open API for advanced users:

For tech-savvy users, the go-e Charger’s open API enables PV surplus charging via custom programming. This approach requires programming skills to ensure smooth communication between the inverter, Energy Management System, and the charger.

With flexible electricity tariffs, your go-e Charger helps you save money by charging your car when electricity is cheapest. For charging with a flexible tariff, you will need a smart meter. If it is not already installed, contact your network operator. You should also switch from your current electricity provider to a provider whose electricity tariff is integrated into the go-e Charger. In Austria, this could be, for instance, smartENERGY and Energie Steiermark.

The actual charging process with a flexible tariff can be set via the go-e app. In “ECO mode,” the charger automatically checks real-time prices from your energy provider and only charges when the cost meets your settings. If you need your car charged for a specific trip, the “Next trip” mode ensures its battery is full on time while still picking the cheapest hours to save you money. 

No additional hardware is required for static load balancing with multiple charging stations. The charging stations can be combined into a load-balancing group via the app, allowing the stations to exchange data with each other via the cloud (Internet connection required). As a result, the performance of individual charging stations is automatically adjusted downwards or upwards depending on the number of vehicles being charged. Priorities for individual charging units can be set in the app.

Yes. The prerequisite for this is that the wallbox is connected to the go-e Controller*. The controller harnesses dynamic load balancing, intuitively adapting to your household's ever-changing energy needs.

*Alternatively, another EMS (e.g. one from go-e integration partners) can be used for dynamic load balancing

For the go-e Charger PRO CABLE and PRO CABLE ME, no additional charging cable is required, as they come with an attached type 2 cable. 
For go-e Charger Gemini (2.0) series with a type 2 socket, you will need a separate charging cable with a type 2 plug. Most new electric vehicles are equipped with a type 2 socket. Older vehicles with a type 1 socket can also be charged with the go-e Charger by using a type 1 to type 2 adapter cable. That means, the go-e Charger can be used universally. It charges every electric car approved for Europe.

As soon as a go-e Charger has been mounted or installed, you can immediately start the first charging process. With a portable go-e Charger you don't even need an electrician to install it.

The original go-e adapters enable charging of electric vehicles with the go-eCharger HOME+ or go-e Charger Gemini flex (incl. 2.0 version) at any socket. Whether at home at the 16 A three-phase socket, in the harbour and on the camping site at CEE blue 16 A or when visiting relatives at a 16 A domestic socket. With the 22 kW variant of the go-e Charger, automatic reduction of the charging current to 16 A by plugging in the adapter is only possible in conjunction with original go-e adapters. We recommend a maximum charging current of 10 A for use with domestic plugs, as very few domestic sockets/electrical installations are suitable for continuous operation with 16 A! National regulations may prescribe lower charging currents.

These communication interfaces provide many additional benefits. If you wish, you can connect the go-e Charger to the Internet (control via app over an existing WiFi network) or control it directly via local hotspot to take advantage of further functions. The go-e Charger 2.0 and PRO series provide identical benefits in addition via cellular connectivity, while exclusively the PRO series offers Ethernet. 

Access to the wallbox can be restricted and personalised using the RFID function. This means that no one can start a charging process without authorisation. In addition, all charging processes can be saved on up to 10 accounts and managed via the go-e app. An unlimited number of accounts can be managed through the API. RFID makes it possible to authorise, and evaluate charges for different users and export them as a CSV file. By default, you can charge without RFID authorisation. This can be changed in the app.

Various settings can be customised via the go-e app. For example, the colours of the charger's LEDs. Bright or colourful — just as you wish. The locking variant of the box can also be configured according to personal needs. In addition, each RFID card can be assigned to a personal account, which makes it possible to read the charged current for each card/user.

The scheduler can be used to determine when to start charging. This is optimal for charging at night or early in the morning, for example (savings potential due to night electricity tariffs). The function also pays off for the environment, similar to the flexible electricity function. By not charging at peak times, voltage peaks can be reduced and the excess current can be used at night.

Installing updates is a major advantage of chargers connected to the Internet. You don’t have to send the go-e Charger to the service to install updates. Updates are easy to initialise via the app.

All basic go-e Charger functions are available without an internet connection. To benefit from smart go-e Charger features, you will need either WiFi (possible with all go-e Chargers), cellular connectivity (only possible with the go-e Charger Gemini 2.0 and PRO series) or Ethernet (only possible with the go-e Charger PRO series). Only the MQTT and Modbus TCP protocols still require WiFi or Ethernet due to the high data volume and technical requirements.

Yes, the display goes off by itself because a brightness sensor is built in.

Select the corresponding item in the menu on the display of the controller. If this no longer works, the unit must be disconnected from the power supply (e.g. switch off the RCD) and, when reconnecting, press the up and down buttons on the controller simultaneously.

This interface is required by chargers only and is implemented in all go-e Cchargers of the HOME series (V3) and Gemini (2.0) and PRO series.

The RFID function is designed to personalise access to the charging station. This means that no one can start the charging process without authorisation.

The access control can be set via the go-e app in such a way that RFID identification is required before charging. If the identification is unknown, the go-e Charger is not released for charging.

All charging processes can be saved on up to 10 accounts and managed via the go-e app, while an unlimited number of accounts can be managed through the API.

Most RFID cards or RFID chips can be trained for the go-e Charger. This means you can also use your EC/bank card, for example. Should it not be possible to train the RFID card, it doesn’t transmit at the required frequency of 13.56 MHz.

If you have recently purchased a go-e Charger, the supplied RFID chip has already been programmed. However, if you would like to teach in another RFID chip, you need to open the go-e app and select ‘Authentication required’ under ‘Access control’ in the security settings. Then click on ‘RFID chips’, select one of the free RFID accounts and give it a name if required.

In the next step, hold the new RFID chip to the RFID reader of the go-e Charger (Gemini (2.0) series: below the go-e logo). Five red LEDs should now light up at 12 o'clock. As soon as these light up on the charger, click on the ‘Connect RFID chip’ button in the app. The five red LEDs should now have disappeared and the five green LEDs should light up instead. 
Your new RFID chip has now been successfully paired. 

By the way, if it is not an RFID chip from go-e, make sure that it has a frequency of 13.56 MHz when you buy it. It is also important that it is not a chip that keeps changing its ID, as is the case with debit cards, for example.

No, the chargers from go-e are maintenance-free.

If you have a technical problem with the go-e Charger and have not found a solution in the user manual, FAQ or troubleshooting guide, you should first contact our technical support. This can be done via email, the support form on our website or telephone. In many cases, we can resolve the problem without the need for repair.

Please contact our support before disassembling the go-e Charger and wait for their decision on how to proceed with the service case. For safety reasons, an allegedly defective, stationary-installed go-e Charger may only be dismantled by a qualified electrician. 

Wipe the wallbox with a cloth moistened with water. Please do not clean the charger with a high-pressure cleaner or under running water to avoid damage.

Information about the firmware and updates (software updates) can be found in the app in the "Settings" tab under “About”.

Updates require the go-e Charger to be actively connected to the internet. As soon as a connection to the Internet is established, possible updates are displayed in the app in the ‘Settings’ and ‘About’ menu.

Fine-wire fuses are only required for the go-eCharger HOME series. A replacement fuse is already enclosed with the units. You need a 2 A ceramic fuse with a breaking capacity of at least 1500 A. The fuses are available in our shop.

To update the firmware, open the go-e app. Click on the ‘Settings’ tab. Go to ‘About’ and select ‘Firmware’. There you can see whether the firmware is up to date.

The update will now take approx. 2 - 5 minutes. After the update, a tick appears next to the current version.

If you want to change back to the previous version, you can do so here under ‘Switch to ***’.
