go-e controller

PV surplus charging & more

With the go-e Controller, you can charge your electric car or plug-in hybrid in conjunction with a go-e Charger even more cheaply, safely and sustainably:

• Photovoltaic surplus charging to optimize your self-consumption
• Dynamic load management to protect against power outages
• Energy monitoring
• Manufacturer's guarantee: 24 months

The go-e controller

The go-e controller ensures that excess electricity from a PV system is used to charge electric cars. This way, you get the most out of your investment in a PV system because you increase your own consumption. Using dynamic load management, the go-e controller prevents the house connection from becoming overloaded by automatically reducing the charging power for electric cars and plug-in hybrids connected to go-e chargers when peak loads 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* as well as AC battery storage systems.

*PV optimization is also possible without direct measurement of production by the inverter. Self-production can be measured and visualized via a sensor only for AC inverters.

Energy monitoring with the go-e controller

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 power demand in a building, charging processes for electric cars can be controlled even more intelligently in conjunction with go-e chargers.

You can also use the go-e controller to simply monitor consumers. This way, you can keep an eye on the energy flows of heat pumps, air conditioning or saunas, for example. The go-e controller can be operated in 1-phase or 3-phase mode.

With three-phase power grids, you can monitor 3 additional devices (e.g. PV inverter, AC battery storage and heat pump), and with single-phase power grids, you can even monitor 1 additional devices.

Self-consumption optimization: PV surplus charging

With the go-e Controller you can charge excess solar energy into the batteries of electric vehicles via one or more go-e Chargers.

If your PV panels generate more energy than is needed to operate your household appliances, you can increase your own consumption by charging them and save a lot of money with green energy. The PV surplus charging and dynamic load management functions do not require measuring PV production.

However, by measuring directly on the AC connection of the inverter, the 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 (with hybrid inverters with a DC battery connection, direct measurement of the battery power is not possible). It is up to you whether charging should be carried out exclusively with surplus PV power or also with mains power.

Automatic phase switching**

If your PV system generates at least 1,4 kW of excess energy, the go-e Controller transmits this information to the go-e Charger, which then takes care of the actual charging process using excess PV power.

The controller automatically switches between single-phase and three-phase charging depending on the available power. This means you can achieve high self-consumption even when PV surplus production is low. As soon as your PV system produces enough surplus, the go-e controller switches to 3-phase charging.

**Only available for HOME Series V3 and Gemini Series.

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 several electric cars. However, you would have to plan for a buffer here, as there are other power consumers 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 go-e controller is automatically adjusted. As a result, your household appliances and charging stations do not consume more power at once than your house connection can handle. And it does this fully automatically.

Comfortable control from the couch

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

Advanced features for experts and integrators

Do you have programming skills? Get even more control when charging an electric vehicle. The go-e 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.

Where is the go-e controller installed?

An electrical distribution board is recommended as the installation location. If this no longer offers enough space, it is also possible to install the go-e controller in a new surface-mounted/flush-mounted distribution board next to it and run the connection cables for voltage measurement and current transformers there.
