go-e Charger CORE: Smart Home Charging
A Detailed Overview of the Features, Capabilities, and Limitations of a Home Wallbox
The Austrian go-e Charger CORE is a stationary wallbox designed primarily for home use. It is aimed at electric vehicle owners who want more than just a basic charger; they want to control the power output, charging process, and timing, while also having the option to integrate the wallbox with their home energy system. It offers up to 22 kW of power, a permanently integrated 6-meter Type 2 cable, and features for controlling and monitoring the charging process.

*Unlike the go-e Charger PRO model, it lacks a MID-certified electricity meter designed for accurate billing to third parties. The CORE is therefore primarily intended for home use, where certified metering for billing is not a primary requirement.
Design, Performance, and Everyday Use
The CORE supports both single-phase and three-phase connections. It comes limited to 11 kW (16 A) out of the box, but an electrician can unlock it to the full 22 kW (32 A) provided the electrical wiring is suitable. With a single-phase connection, it reaches a maximum of 7.4 kW.
A practical feature is the permanently integrated 6-meter Type 2 cable. This eliminates the need to pull your own cable out of the car every time you charge, which can simplify everyday use. The IP66 rating allows for installation in a garage or an outdoor parking space.
The device measures approximately 18.6 × 29.7 × 9.9 cm and weighs about 5.1 kg, including the cable. In terms of its basic specifications, it is a compact home wallbox that combines an integrated cable with a power output of up to 22 kW.
Smart Features and Energy Management
CORE’s strengths lie not only in its performance specifications but also in its charging control capabilities. Through the app, you can monitor the charging process, adjust the charging current in 1 A increments, and use scheduling or charging based on dynamic rates.
The wallbox supports both static and dynamic load control. Dynamic control is possible, for example, via the go-e Controller or an external energy management system. Open interfaces—HTTP API, MQTT, OCPP 1.6, and Modbus TCP—enable integration into a smart home or a custom energy management system.
This openness is particularly important for tech-savvy users. If someone simply wants to plug in the wallbox and charge their vehicle, they don’t need to use all the advanced features. However, if they plan to integrate it with other systems in the home, the CORE offers more options than standard basic wallboxes.
Mobile App and Control
The go-e app displays the current charging status, history, consumption, power settings, and scheduling options. This allows you to perform basic controls without having to interact directly with the device.
Wi-Fi and Bluetooth are available, as well as LTE with a prepaid data plan and a LAN connection. The Wallbox can therefore be managed remotely, and you can monitor the charging process even when you’re away from home.
Solar Power and Smart Homes
Charging using surplus solar power is possible via the go-e Controller, an open API, or another energy management system. The Wallbox can be configured to respond to available surplus power from solar panels or to electricity prices under dynamic rates and time zones.
It is important for photovoltaic system owners to keep in mind that automatic surplus management typically requires an additional component, such as the go-e Controller or another compatible HEMS. The wallbox itself, therefore, may not be the only device needed for fully automated charging control based on the output of the home power plant.
Installation, Safety, and Reliability
The power cable can be connected from the top, bottom, or rear, providing some flexibility during installation. The device features 6 mA DC residual current detection, overheating protection, and voltage and current monitoring.
An LED ring on the front panel displays information about the current charging session, including the amount of energy charged during that session. We really appreciate this user-friendly solution. RFID access is standard, and one chip is included in the package. These features complement the device’s basic safety and control features.
Price and Price-Performance Ratio
At the time of writing, the price of the go-e Charger CORE in the Czech Republic typically ranged from 22,000 to 23,000 CZK, depending on the retailer. The price includes an integrated cable, extensive connectivity options—including LTE—and open interfaces for integration.
In terms of hardware, the device is ready for V2X and Plug&Charge in accordance with ISO 15118, though software activation of these features is planned for a later date. When evaluating the price, it is therefore necessary to take into account not only the performance itself, but also connectivity, control options, and readiness for additional features.
Prices may vary among retailers, so it’s a good idea to check current offers before making a purchase—and, if necessary, also check the prices of any accessories you’ll need for your specific home energy management system.
Who Is the go-e Charger CORE Suitable For?
The CORE makes the most sense primarily for owners of single-family homes with an electric vehicle who want more control over charging than simply plugging in the car and starting the charging process. It allows you to set the charging power and duration, monitor the charging process, and—when used with additional accessories or a HEMS—integrate it into your home energy management system.
It is also suitable for users with a solar power system who want to utilize surplus energy from their own generation, as well as for tech-savvy users who appreciate support for OCPP, HTTP API, MQTT, Modbus TCP, LAN, Wi-Fi, LTE, and RFID.
Another advantage is the ability to operate at up to 22 kW with the appropriate electrical installation. The “V2X ready” designation indicates that the hardware is prepared for future bidirectional charging technologies, such as V2H or V2G. However, it is important to view this readiness as a future possibility, not as an automatically available feature that can be used today without additional conditions.
Is the go-e Charger CORE worth it?
The go-e Charger CORE is a home wallbox with an integrated 6-meter cable, a power output of up to 22 kW, and extensive control and monitoring capabilities. Its main advantage is the combination of home use, open interfaces, connectivity, and the ability to integrate it into a photovoltaic system or a smart home.
Advantages
- Integrated 6-meter Type 2 cable
- Power output up to 22 kW
