The go-e controller ensures that excess current of a PV system is used for charging electric cars. So you get the Maximum out of your investment in a PV plant, as you increase your own consumption. Thanks to dynamic load management, the go-e controller prevents overloading of the house connection by automatically reducing the charging capacity for electric cars and plug-in hybrids connected to go-e chargers and increasing them 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.
Energy monitoring
With the go-e controller you monitor the energy flows of buildings. As a result, charging processes in electric cars together with go-e chargers can be controlled even smarter, depending on the position of the sun and the current power consumption in a building. Alternatively, you can easily use the controller to monitor consumers. For example, you can keep an eye on the energy flows of heat pumps, air conditioning or sauna. A 1-phase or 3-phase operation of the controller is possible. For three-phase power grids you can monitor 3 other devices (i.e. PV inverters, AC battery storage and heat pump), for 1-phase power grids you can monitor 5 other devices.
Self-consumption optimization: Efficiently use excess PV current
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 required to operate your household appliances, charging increases your own consumption and saves money with self-generated energy. No PV production measurement is necessary for the PV surplus load and dynamic load management functions. However, due to direct measurement at the AC connection of the DC-AC converter, your own consumption can also be displayed correctly. Direct communication with the PV system is not necessary. Battery storage systems can also be taken into account as long as they can be measured at the AC connection (for hybrid converters with DC battery connection, direct measurement of the battery power is not possible). You can use it to charge only with PV excess current 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 and takes care of the actual charging process with PV excess current. The controller automatically switches between single-phase and three-phase charging depending on the available current. This means that even with low production of PV surplus, you can achieve high self-consumption. As soon as your PV system produces enough surplus, the controller switches to 3-phase charging.
Dynamic load management for protection against power failures & 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 current of your building when charging multiple electric cars. However, you would have to plan a buffer as there are more electrical loads in the building. Therefore, the go-e controller enables dynamic load management. If a lot of consumers are 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 power at once than your home connection can bear. Fully automatic.
Comfortable 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, in order to access all settings of the controller and adapt them to your needs. Whether dynamic load management or power consumption in your building. You keep everything in view. Once the controller is connected via WLAN or via LAN, charging your electric vehicle becomes even easier, safer, more economical and future-proof.
Advanced functionality for experts and integrators
Do you have programming skills? Get even more control when charging an electric vehicle. The controller has additional interfaces such as local HTTP-API, Modbus TCP and MQTT. The optional cloud connection allows you to further optimize the functions of the controller.
