go-e Charger Gemini flex 11kW + go-e Controller

go-e Controller

The go-e Controller ensures that surplus electricity from a PV system is used to charge electric vehicles. In this way, you get the most out of your investment in a PV system because you increase your own consumption. Using dynamic load balancing, the go-e Controller prevents an overload of the house power supply by automatically reducing the charging power for electric cars and plug-in hybrids connected to go-e Chargers during detected load peaks and increasing it again later.

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

Energy monitoring

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 smarter in interaction with go-e Chargers. But you can also simply use the Controller to monitor consumers. For example, you can keep an eye on the energy flows of a heat pump, air conditioning system or sauna. 1-phase or 3-phase operation of the Controller is possible. In the case of three-phase power grids, you can monitor 3 additional devices (e.g. PV inverter, AC battery storage and heat pump), in the case of single-phase power grids even 5 additional devices.

Self-consumption optimisation: Efficient use of surplus solar power

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 needed to operate your household appliances, you increase your self-consumption by charging and thus save a lot of money with green energy. For the PV Surplus Charging and dynamic load balancing functions, no measurement of PV production is necessary. However, by direct measurement 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 battery power is not possible). It is up to you whether you want to charge exclusively with PV surplus electricity or also with mains electricity.

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 can achieve high self-consumption even with low production of PV surplus energy. As soon as your PV system produces enough excess power, the Controller switches to threephase charging.

Dynamic load balancing to prevent Blackouts & Peak Shaving

To avoid power cuts, you need a load balancing system when charging electric vehicles. The go-e Charger already offers static load balancing, which allows you to take into account the maximum available power of your building when charging several electric cars. However, you would have to plan a buffer, as there are other electricity consumers running in the building. Therefore, the go-e Controller enables dynamic load balancing. If necessary due to many electricity consumers running at the same time the charging power of the go-e Chargers 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 house connection can handle. And that fully automatically.

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 controller settings and adjust them to your needs. Whether dynamic load balancing or electricity consumption in your building. You keep an eye on everything. Once the controller is connected via WiFi or Ethernet, charging your electric vehicle becomes even simpler, safer, cheaper and more sustainable.

Advanced functions for experts and Integrators
