2. Smarter Charging

Thank you for your purchase. With the go-e Controller, you monitor the energy flows in your building. Consequently, charging processes for electric vehicles can be controlled even more intelligently based on solar energy and the current electricity demand of a building, in conjunction with go-e Chargers. You can also easily use it to monitor consumers in the building.

The go-e Controller helps you, as an energy management system (EMS), to record measurement values in an electrical distribution system and make these other devices available in a network. This enables, among other things, PV surplus regulation and dynamic load management with go-e Chargers without additional programming knowledge.

Keep an eye on the current flows in your building and thus automatically maximize your own photovoltaic system's self-consumption when charging with all go-e Chargers. For go-e Chargers of the Gemini, Gemini 2.0, PRO, and Home (V3) series, this also applies to automatic phase switching.

Control the charging process of electric vehicles with dynamic load management to avoid overloading your electrical connection. If necessary, due to numerous simultaneously operating current consumers, the charging power of the go-e Chargers connected to the go-e Controller is automatically adjusted.

The go-e Controller is compatible with all photovoltaic inverters and all battery storage solutions. Furthermore, it is also compatible with all go-e Chargers and the go-e app.

The go-e Controller allows for a real-time graphical representation of electricity consumption and past consumption. The measurement values recorded by the go-e Controller are recorded directly by the supplied current transformers and the voltage supply provided by the electrician. The go-e Controller can be operated in single-phase or three-phase mode.

Note: PV optimization is also possible without direct measurement of production by the inverter. Internal production can only be measured and visualized by a sensor for AC inverters.

Summary: The go-e Controller controls an unlimited number of chargers so that these electric vehicles charge when there is enough current. Depending on the need, with or without grid electricity.

The go-e Controller can be operated directly via a display. With the go-e app, operation is even more convenient.

Integration of the go-e Controller into a network can be done via WLAN or LAN. The go-e Controller also offers other interfaces for connection to existing solutions: In addition to the HTTP API, MQTT, and Modbus, a cloud API is also available to integrate the go-e Controller.

Note: A lot of information in this manual is intended for the installer who must perform the installation and basic configuration. The user can comfortably implement settings for optimized charging processes and the connection of other charging stations to the go-e Controller via the go-e app in just a few steps.

Tip: PV surplus charging can even be combined with flexible electricity prices. This ensures even more sustainable and economical charging processes.

We wish you a lot of fun with your go-e Controller.

Your go-e team

8. Installation Diagram

Warning: Entrust the installation and configuration of the go-e Controller to a qualified electrician in accordance with local installation standards.

Recommendation: The recommended installation location is an electrical distributor. If there is no more space, the go-e Controller can also be installed in a new distributor, surface-mounted or flush-mounted, and the connection cables for voltage measurement and current transformers can be routed there.

Once the installation is complete, note that the firmware of the go-e Charger and the go-e Controller must always be up to date to ensure proper functioning at all times. The firmware of both products can be updated, for example, via the go-e app in the "Internet" menu item.

RCD/FI

The diagram shows the wiring connections for a three-phase installation, including the go-e Controller, RCD/FI, and a kWh meter.

8. Installation

Tools Required

• Screwdriver

Steps

1. Ensure absence of voltage by following the five electrical safety rules.
2. Mount the go-e Controller on the DIN rail. We recommend mounting as shown in the illustration. The go-e Controller can also be mounted rotated by 180°.
3. Connect the go-e Controller to the single-phase or three-phase power supply, depending on the electrical connection. If necessary, install an additional power line. Insert the conductors into the connection terminal and secure them with a screwdriver. Also connect the neutral conductor and the protective conductor.
4. The go-e Controller can also be connected to another consumer, such as an electric stove, via a fuse. If this is not possible, you must install a new circuit breaker.
5. For photovoltaic surplus optimization, we need enough sensors to measure the power from or to the grid. For a three-phase connection, plug the jack plugs of three current transformers into the provided inputs for current measurement. For example, into sensors one to three. Use a single current transformer for single-phase connection. The easiest way to do this is to measure directly at the grid connection point.
6. Attach one current transformer per phase. The two arrows on the current transformer must point in the direction of current flow. When connecting to the grid, which we call the "grid", the arrow on the grid connection must point towards the house.*
7. Note: A maximum of one current transformer can be attached to a phase.
8. Connect the Wi-Fi antenna and/or LAN cable to the go-e Controller.
9. For optimal reception, route the Wi-Fi flat cable out of the control cabinet to place the head part there.
10. Do you not want to connect other sensors? (This is also not necessary for PV surplus optimization.) Then restore the power supply. Then follow the instructions in section 5 of chapter 9. Installation (Other Sensors).
11. Note: The display can be rotated accordingly under the menu item "Settings/Device/Rotate Screen".
12. Note: If it is not possible to install the current sensors with the arrow in the indicated direction due to space constraints, the sensors can also be reversed via the go-e Controller menu or the app.

9. Installation (Other Sensors)

Once the basic installation is complete, you can use the remaining 3 to 5 current transformers to measure the current flows of different devices or groups of consumers in the building, depending on the connection type (single-phase or three-phase). This can be the case, for example, for the AC-PV inverter, an AC battery storage system, or large electrical consumers such as a water heater, air conditioner, or heat pump.

PV optimization is also possible without direct measurement of production by the inverter.

Ensure absence of voltage by following the five electrical safety rules.

Example: Measuring your own photovoltaic production?

If you want to measure and visualize your own photovoltaic production, you must measure the current using a sensor on one phase of your AC-PV inverter. In the case of a solar inverter, the arrow on the current transformer of the inverter must point towards the distributor.

Example: Using a battery storage system?

Do you have a battery storage system that needs to be considered in the optimization of electricity consumption?

Use a current transformer to measure one phase of the AC battery storage system. On an AC battery, the arrow on the current transformer must point from the battery to the distributor. A DC-coupled battery cannot be measured, but it can be prevented from being permanently discharged when charging the electric car by setting it in the app (not with HOME V2.).

Step 2: Plug the jack plug of a current transformer into one of the free inputs for current measurement marked "Sensor". You can assign them as you wish. Clip the current transformer onto a phase of the device or circuit you want to measure. For three-phase instruments that supply the same power on all phases, measuring a single phase is generally sufficient. For example: for the AC inverter. It should be noted that a maximum of one current transformer can be attached to a phase, otherwise no measurement value can be captured.

Example: Measuring three-phase consumers?

The connection of a current transformer is also sufficient for measuring the current of other large three-phase consumers. You can also use the current transformers to measure the consumption of individual circuits, such as lighting, a water heater, air conditioning, a sauna, or a heat pump. When measuring these loads, the arrow on the current transformer must point towards the load.

Step 4: Have you installed all current transformers or do you not want to use all sensors? Are the electrical connections finished? Then restore the power supply to the electrical circuit.

Step 5: The go-e Controller will turn on and be ready for operation after the system starts up. It is still likely that incorrect measurement values will be displayed on the screen; we still need to assign the correct phase and category to the sensors. You must now proceed with the initial configuration. For this, you can choose between these two methods:

• a) Commissioning/Operation via the device's buttons and screen
• b) Configuration via the app

If you have already mounted the go-e Charger, it will detect it automatically once the go-e Controller configuration is complete. For this, the go-e Controller must be in the same network as the chargers. The go-e Controller can be connected to an unlimited number of chargers.

Note: When using Wi-Fi repeaters, it should be taken into account that they extend your home network and do not create a new network with a different IP address. It is best to use repeaters from the same manufacturer as your Wi-Fi access point or router.

10a. Commissioning/Operation via the Device

1. Home Screen

As soon as the go-e Controller is ready for operation, you can see the first measurement values on the home screen, which are likely still incorrect. Sensor configuration is described later.

To access the main menu, press the > button without selecting a category. Go back using the < button.

2. Main Menu/Settings

The up and down buttons on the device allow you to navigate from one menu item to another.

To select the "Settings" menu item, press the > button.

3. Settings/Device

To select the "Device" menu item, press the > button. Here you can, for example, adjust the language or the screen of the go-e Controller to your preferences.

4. Device

In the "Device" submenu, you can, for example:

1. Rotate the display by 180° if you have mounted the go-e Controller upside down due to space constraints.
2. Select your preferred language.
3. Adjust the display brightness.
4. Adjust the screen brightness in case of inactivity.
5. Set the inactivity timeout after which the screen should turn off completely.

5. Main Menu/Sensors

To select the "Sensors" menu item, press the > button. In the "Sensors" menu, you can perform the configuration.

6. Sensors

In the "Sensors" menu, you can read the voltages, currents, or powers in real-time. L1 to L3 indicates the voltage of the connected phases at the connection terminal. 11 to 16 displays the values of the connected sensors (current transformers). Here, I corresponds to the designation "Internal", which corresponds to the connected sensor or load.

If you select L1, L2, L3, or N, you access the voltage settings for the phase.

Here you can see all the measurement values of the selected phase as well as the assigned loads (Internal/current transformers). Simply check if the voltage is approximately correct. If the current and total power are not yet correct, that is not a problem, as this configuration will be explained later.

Note: If you have incorrectly connected one or more phases of the power supply, you can also change the phase assignments by going back to "Sensors" in the menu, scrolling down, and selecting the option with the > button.

7. Sensors/Voltage Settings

If you select one of the loads (11 to 16) on the "Sensors" page, you will access the "Load Settings" overview.

Here you can invert a load using the slider if you have not connected a current transformer with the arrows pointing in the direction of current flow.

For the power calculation to be correct, the phase must be set correctly. Imagine that the sensor measures 2 amperes at your grid connection, but without a voltage reference, we do not know whether we are feeding power into the grid or drawing it. The test is particularly easy, as all phases are directly loaded with a power factor of almost one. If the power factors are incorrect and, for example, the plus or minus is equal to two-thirds, you must change the assignment. As long as the assignment is not correct, your go-e Controller cannot differentiate between feeding into and drawing from the grid, and PV surplus regulation will not work.

The power factor can be between minus one and plus one. Minus one means maximum feed-in or load for a battery with no reactive power, plus one means maximum consumption or production of energy. If the power is particularly low, the power factor is not very relevant.

This submenu also allows you to define the load categories by navigating to "Categories" and confirming with >.

Configuration in the App

You can also perform many configuration steps on the device via the app. For certain functions, such as controlling PV surplus or dynamic load management by the various chargers, integration of the go-e Controller into the app is absolutely necessary.

If you have already configured a go-e Charger, you must return to the device list. If the go-e Controller was already configured, you would see it in the device list. If you have not yet configured the go-e Controller, press "Add or setup device" to configure it.

• a) Use "Configure go-e device" if your go-e Controller has never been configured in a go-e app before.
• b) If you have already connected your go-e Controller directly via the screen or with the go-e app to the home network, select "Add go-e device".

Configuration in the app

If you want to add an already configured go-e Controller, select "Add go-e device" and enter the go-e Controller's serial number. This is also found on the data card supplied with the go-e Controller. Then enter the password. This is either the default password indicated on the data card or the password you assigned during initial setup, then click "Connect".

To connect to the access point, simply scan the QR code on the data card included with the go-e Controller or manually connect to the go-e Controller in your phone's Wi-Fi settings using the access point password found on the go-e Controller's rating plate. The procedure is comparable to the configuration of the go-e Charger.

Home Screen

On the home screen, you can see the current power consumption of the different categories. The categories Solar, Grid, Home, and Battery are displayed here by default. The corresponding values are only available if the configuration has been carried out accordingly.

Information

You will find more detailed information on the categories and sensors in the "Information" menu item.

Here, for example, all energy flows are displayed as a list.

In the "Information" tab, you will see diagrams of your energy flows over the past few hours. It is also possible to export all data from the go-e Controller and view it on a PC.

Settings

In the "Settings" menu of the app, you can configure the sensors, assign them to categories, and adjust them via the different submenu items, just like directly during configuration on the go-e Controller. Time and display settings can also be configured via the app.

In addition, you can give the go-e Controller a name or change the password you chose during initial setup.

Important: If you have performed the configuration directly from the controller's menu, you no longer need to perform important settings for the go-e Controller in the app. You can proceed directly to the end of chapter 10b of this manual.

Settings/Configuration of the sensor/Sensors

As with the go-e Controller, you can configure the voltage sensors and current sensors in the "Settings" menu, submenu "Sensor/Sensor Configuration", and read them after selecting their real-time voltages, currents, and powers. You can also do this directly on the go-e Controller.

For voltage sensors L1 to L3, the connected phase voltage is always measured, and for current sensors Internal 1 to Internal 6, the current and power are always measured. For the power calculation by the go-e Controller to be truly correct and for functionalities such as PV surplus charging and dynamic load management to work correctly, you must ensure that you have set the correct reference voltage for all phases and that the correct categories and power factors are stored. We explain in this manual what needs to be observed exactly in chapter "10a. Commissioning/Operation via the Device" using various examples.

In the following, we will only explain where to find which parameters in the app.

Settings/Configuration of the sensor/Voltage Sensors

If you select one of the voltage sensors, e.g., Voltage Sensor L1, you will see all the measurement values for the selected phase.

If you have incorrectly connected one or more phases of the power supply, you can also change the phase assignments by tapping on "Phase assigned".

Settings/Configuration of the sensor/Current Sensors

If you select one of the Internals 11 to 16 (loads) in the "Sensors" view, you will access the overview of the sensor/Internal data. In the settings directly on the go-e Controller, you will find a similar view under "Load Settings". Here you can invert a load using the slider if you have not connected a current transformer with the arrows pointing in the direction of current flow. Note that the power must always be positive when using the grid. In the case of a solar inverter or an AC battery, the power must be positive during feed-in. However, if the battery is charged or the inverter has a higher standby consumption than production, the power can be negative. In the absence of current consumption, the power should be close to 0.

If you want to adjust an assigned load category or change the phase assignment, you can also do this here in the current sensor overview. This works the same way as via the go-e Controller menu.

Settings/Configuration of the sensor/Categories

In this submenu, you see an overview of the categories. Select a category and enter a number for the factor in the following submenu with which this electrical load should be taken into account.

For PV solar installations with a three-phase AC inverter and only one sensor on one phase, you must set the factor for the "Solar" category to 3 for the corresponding sensor so that the total power of the PV installation can be displayed correctly. This works here because a three-phase inverter supplies the same power on all phases. This saves you two sensor connections for other uses.

For custom categories, you can even change the name of the category, for example: for a water heater if you measure it with a sensor.

Settings/Configuration of the sensor/Category Overview

Press "Categories" in the "Settings" menu to access the "Sensor Configuration" screen. Here you can select the different categories to then assign the selected category to the connected sensors. This is therefore an alternative for linking loads and sensors.

For example, if you measure your grid connection using a sensor, you must assign the factor 1 to this load in the "Grid" category. If you do not have a sensor on the grid connection, i.e., on the rest of your household, you must also assign the "Home" category with the factor 1.

Settings/General/Date and Time

Advanced users can synchronize the time via an NTP server or the app here. If the go-e Controller is connected to the go-e Cloud via the Internet, it always obtains the current time from it. In this case, no setting is necessary. In the time settings, you can set the time zone and activate automatic daylight saving time.

11. PV Surplus Charging/Load Management

Home Screen (go-e Charger)

After switching from your go-e Controller to the go-e Charger, you will access its home screen with the "Charger" view.

Memorize the mode buttons here (Eco, Daily Trip) which you will later tap with your fingertip to activate PV surplus charging.

First, switch to the "Settings" view.

Settings (go-e Charger)/General/go-e Controller

Already installed go-e Controllers can be automatically integrated into the go-e app. Normally, go-e Controllers are searched for automatically. You only need to tap "Scan now" here if the go-e Controller has just been installed or if you have deactivated the automatic scanning function. A charger can only be connected to one go-e Controller, but the go-e Controller itself can be connected to an unlimited number of chargers simultaneously.

Settings (go-e Charger)

Select the "General/go-e Controller" setting option if your go-e Charger is not yet connected to your go-e Controller. You can also check the connection there.

Eco/PV Surplus

Once you have verified that your go-e Charger is connected to the go-e Controller, you can now make the settings for PV surplus charging.

To do this, select the "Eco" tab in the menu at the bottom, then "PV Surplus". If you have an electricity provider with flexible electricity prices listed in the go-e app, you can also combine PV surplus charging with the corresponding electricity tariff. However, this is not absolutely necessary for PV surplus charging.

Now activate the "Charge with PV surplus" slider and then proceed with the detailed settings for charging with solar electricity.

Daily Trip

Decide here from which power level the photovoltaic system should start the charging process. If the power is below 1.4 kW, mains power should also be used. Furthermore, you choose whether you prefer to draw a little electricity from the grid or feed it in during surplus charging, or if you prefer to use a mixed form. This is necessary because you can only charge your electric car at certain power levels. In addition, you can define whether the charger should adapt the phases based on the power of the photovoltaic system using the go-e Controller and from which power the charging should take place in 3 phases.

Do you have a DC-coupled battery storage system? In this case, enter the value -200 under "Grid target value", which will prevent the DC battery from being permanently discharged when charging the electric car (not possible with the HOME V2 series). At the same time, under "Power preference", the option "Prefer grid power" must be selected.

You will find more detailed information on these details in our go-e Controller App video on YouTube.

Settings (go-e Charger)/Charging Process Configuration/Daily Trip

You can also activate PV surplus charging with the Daily Trip mode. If you want to ensure that the go-e Charger charges your car by early morning with a certain amount of energy and you want to use photovoltaic electricity or cheap electricity from an electricity provider with flexible tariffs, you must activate the "Daily Trip Mode".

To do this, go to "Settings", then to "Charging Process Configuration", and finally to "Load Management".

With your go-e Controller, you can combine static and dynamic load management.

Enter the value for dynamic load management in the "Maximum grid current" line. This is the current in amperes that your house can use at most.

The go-e Controller will ensure that this value is never exceeded when charging your car in combination with the current needs of your other consumers. If necessary, the go-e Controller will regulate the charging power downwards and then upwards.

12. Warranty and Exclusions
