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 Flex) 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.
