go-e Controller

The go-e Controller

The go-e Controller ensures that surplus electricity from a PV system is used to charge electric cars. In this way, you get the most out of your investment in a PV system because you increase your own 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, Gemini 2.0 and HOME series) and all types of PV inverters* and AC battery storage systems.

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

Energy Monitoring with the go-e Controller

With the go-e Controller, you 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 of electric cars can be controlled even more intelligently in interaction with go-e Chargers.

But you can also simply use the go-e Controller to monitor consumers. For example, you can keep an eye on the energy flows of your heat pump, air conditioner or sauna. 1-phase or 3-phase operation of the go-e controller is possible.

With three-phase grids, you can monitor 3 additional devices (e.g. PV inverter, AC battery storage and heat pump), with single-phase grids even 5 additional devices.

Self-consumption optimisation: PV surplus charging

With the go-e Controller, you 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 increase your own consumption by charging and thus save real money with green energy. For the PV surplus charging and dynamic load management functions, no measurement of PV production is necessary.

However, by measuring directly at the AC connection of the inverter, self-consumption can also be displayed correctly. No direct communication to 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 output is not possible). It is up to you whether you want to charge exclusively with PV excess current or also with mains 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, which then takes care of the actual charging process with PV surplus power.

The controller automatically switches between single-phase and three-phase charging depending on the available current. In this way, you realise a high level of self-consumption even with low production of PV surplus. As soon as your PV system produces enough surplus, the go-e controller switches to 3-phase charging.

**Only available for HOME series V3, Gemini series and Gemini series 2.0.

Dynamic Load Management for Power Outage Protection & 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 of your building when charging several electric cars. However, you would need to plan for a buffer, as there are other power consumers running in the building. Therefore, the go-e controller enables dynamic load management.

If necessary due to many electricity consumers running at the same time, the charging power of the go-e Chargers connected to the go-e Controller is automatically adjusted. As a result, your household appliances and charging stations do not consume more electricity at once than your house connection can handle. And it's fully automatic.

Convenient control from the couch 

Set your preferences for solar energy production and consumption via the app, right from your couch. Or use the go-e app to access all the controller settings and adjust them to your needs. Whether 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 functions for experts and integrators 

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 controller's functions can be optimised even further.

Where is the go-e Controller installed? 

An electrical installation distributor is recommended as the installation location. If there is no more space, it is also possible to install the go-e Controller in a new surface-mounted / flush-mounted distributor next to it and to lay the connection cables for voltage measurement and current transformers there.
