go-e Charger Gemini 2.0 22kW + go-e Controller

go-e Charger Gemini 2.0 22kW

The go-e Charger Gemini 2.0 with integrated SIM card and a maximum charging capacity of 22 kW is an intelligent wallbox for charging electric cars at home and at company locations (without charging electricity). Immediately after installation, the device is ready for the first charging process (plug & play). Thanks to the integrated SIM card, you can use all the intelligent functions of the previous Gemini series, even without Wi-Fi.

The charging station has a 1.8 meter long connection cable for permanent connection to a power distribution box. Unlike the go-e Charger Gemini flex, the Charger therefore has no plug and cannot be used on the move. The clever solution for anyone who needs a smart home charging station for wall installation only.

In addition to extensive safety functions such as DC fault protection (RCD module), phase detection and earth measurement, the charging station is also equipped with RFID for access control (activation via app if required) and hotspot/WLAN/4G. PV-Anbindung über die API-Schnittstelle, Lastmanagement und Verwendung flexibler Stromtarife*** gehören ebenfalls zum Funktionsumfang. With the free go-e Charger app, convenience and basic settings can be changed, allowing the device to be adapted to personal charging behavior and inviting more sustainable charging.

go-e Charger Controller

The go-e Controller ensures that surplus electricity from a PV system is used to charge electric cars. This allows you to get the most out of your investment in a PV system by increasing your self-consumption. By means of dynamic load management, the go-e Controller prevents overloading of the house connection by automatically reducing the charging power for electric cars and plug-in hybrids connected to go-e Chargers when load peaks are detected and increasing it again as soon as possible.

*The go-e Controller is compatible with all go-e Chargers (Gemini and HOME series) and all types of PV inverters and AC battery storage systems.

Energy monitoring

With the go-e Controller, you can monitor the energy flows of buildings. As a result, depending on the position of the sun and the current electricity demand in a building, charging processes for electric cars can be controlled even more intelligently in conjunction with go-e chargers. You can also simply use the controller to monitor consumers. For example, you can keep an eye on the energy flows from the heat pump, air conditioning or sauna. Single-phase or three-phase operation of the controller is possible. With three-phase power grids, you can monitor 3 additional devices (e.g. PV inverter, AC battery storage and heat pump), with single-phase power grids even 5 additional devices.

Self-consumption optimization: efficient use of surplus PV power

With the go-e Controller, you can charge surplus solar energy into the batteries of electric vehicles via one or more go-e Chargers. If your PV panels generate more energy than is required to operate your household appliances, you can increase your self-consumption by charging and save real money with green energy. No measurement of PV production is required for the PV surplus charging and dynamic load management functions. However, by measuring directly at the AC connection of the inverter, self-consumption can also be displayed correctly. No direct communication with the PV system is necessary. Battery storage systems can also be taken into account as long as they can be measured at the AC connection (for hybrid inverters with DC battery connection, direct measurement of the battery power is not possible). It is up to you whether you want to charge exclusively with excess PV current or also with grid current.

Automatic phase switching

If your PV system generates at least 1.4 kW of surplus energy, the go-e Controller transmits this information to the go-e Charger and this takes care of the actual charging process with surplus PV power. The controller automatically switches between single-phase and three-phase charging depending on the available power. This allows you to achieve a high level of self-consumption even with low surplus PV production. As soon as your PV system produces enough surplus power, the controller switches to three-phase charging.

Dynamic load management to protect against power outages & peak shaving

To avoid power outages, you need a load management system when charging electric cars. The go-e Charger already has static load management, which allows you to take into account the maximum available power in your building when charging multiple electric cars. However, you would have to plan for a buffer, as other electricity consumers are running in the building. The go-e Controller therefore enables dynamic load management. If necessary due to many power consumers running at the same time, the charging power of the go-e Charger connected to the controller is automatically adjusted. As a result, your household appliances and charging stations do not consume more electricity at once than your home connection can cope with. And it’s fully automatic.

Convenient control from the couch

Set your preferences for the generation and consumption of solar energy via app directly from the couch. Or use the go-e app to access all the controller settings and customize them to your needs. Whether dynamic load management or power consumption in your building. You can keep an eye on everything. As soon as the controller is connected via Wi-Fi or LAN, charging your electric vehicle becomes even easier, safer, more cost-effective and more sustainable.

Advanced functions for experts and integrators

Do you have programming skills? Gain even more control when charging an electric vehicle. The controller has additional interfaces such as local HTTP API, Modbus TCP and MQTT. With the optional cloud connection, the functions of the controller can be optimized even further.
