Questions & Answers

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 with simultaneous use of 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.

Yes, the controller is also compatible with the go-e Charger HOME series (V2 and V3).

Yes, an electrician is required for installation.

No, wallboxes or chargers from other manufacturers cannot be connected via the controller.

No, the installation does not have to be reported to the electricity provider.

The controller consumes four division units on the DIN rail.

Yes, it fits very well into any standard distribution box. There only has to be space for 4 division units.

No, the controller is simply plugged onto the DIN rail. A screwdriver is needed to connect the power lines.

If the go-e Controller does not show your go-e Charger V2, there is no need to worry. It is important that the go-e Charger shows the go-e Controller as "Connected" in its settings and that values are also transmitted. To do this, simply go to your go-e Charger in the go-e app, then to "Settings". Select "go-e Controller" in the settings. Here you should see the go-e Controller under "Connected Controller".

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.

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