You have excess solar power that is not consumed by your household appliances?
Try PV surplus charging with the go-e Charger. Direct the unused power into your electric vehicle's battery and enjoy significant savings on charging.
PV surplus charging is a method of charging electric vehicles using a wallbox that can transfer surplus electricity from an in-house PV system.
In this setup, when all household energy demands are met and there is surplus solar power available, this excess energy is directed to charge the electric vehicle.
With the cost of installing solar dropping by more than 40% over the last few years, adopting solar has become more affordable than ever.* Using solar panels to charge your car means you charge for free and speed up the payback period of your PV system.
From a very factual point of view, charging with PV energy saves you a pretty penny. While initial investment costs are relatively high, the potential savings are more than impressive.
You can significantly increase self-consumption. It is also possible to improve efficiency by switching phases. In this case, even small amounts of electricity can be utilised. In addition, you do not have to feed electricity into the grid for a small fee.
While you are driving your car on solar energy, you are also driving the world into a more sustainable future. Unlike electricity from the grid, which may have caused greenhouse gas emissions, energy from PV panels is always clean and emission-free.
Solar charging without control
This is simple: connect the wallbox to your car as usual and let it charge. However, the issue is that you will have to adjust the phase switching and the charging current manually. That is if you want to charge purely with PV power. All in all, it will not work very well unless you are sitting at home all day and looking at your phone to see how much solar power is available. Not ideal, right?
Straightforward PV surplus charging with go-e Charger and go-e Controller
The go-e Controller tracks the energy usage in your home and starts charging your car automatically as soon as there is excess power available. It adjusts between one- and three-phase charging based on the output from your solar panels. Just set your preferences in the go-e app and let the system handle the rest.
PV surplus charging via integration
You can use an integration from partner brands such as Clever-PV and Solar Manager to manage the PV surplus. As go-e is already integrated into their systems, activating excess charging with solar is going to be quick and simple. Keep in mind that some integrations do not use our API but OCPP for PV surplus.
Surplus solar charging via an open API
As the go-e Charger has an open API, advanced users can activate PV surplus charging through programming. However, certain programming skills are required to make the inverter, Energy Management System (EMS), and charger communicate with each other.
Full control with the app
You have our go-e Charger + go-e Controller combo? Add both devices to the go-e app and activate PV surplus charging. You can also use the app to see the general overview of the energy flows in your house. Keep an eye on how much solar energy has been produced.
Automatic phase switching
Our go-e Charger + go-e Controller combo ensures that you use your surplus solar power in the most efficient way possible. The wallbox adjusts the charging phases based on the available energy. When the solar surplus is between 1.4 kW and 4.2 kW, the car will be charged with one phase; when it is higher, it will be charged with three phases.
Flexible energy tariffs
go-e users have a special opportunity to combine PV surplus charging with favorable dynamic electricity tariffs to top up their car batteries. Once you activate the flexible energy tariffs feature in the go-e app and set an electricity price limit, the go-e Charger automatically looks for the cheapest hours to charge your electric vehicle, when there is no surplus solar power available. Can be adapted to your individual needs.
For home charging with PV surplus, you need a wallbox that supports PV surplus charging. Every go-e Charger in combination with the go-e Controller or via API or an integration is designed precisely for this purpose.

You already have solar panels installed? All you need for PV surplus charging is a smart wallbox and an Energy Management System if you don’t have one yet.
Smart wallbox
With our smart wallbox, the go-e Charger, you get full control over charging. In the meantime, it automatically adjusts the number of phases to match the current amount of surplus solar power available.
Energy Management System
You can use the go-e Controller or an EMS from one of our integration partners. The primary function of this device is to monitor energy flows and identify excess power available for charging your electric car.
A wallbox for PV surplus charging costs between 550 Euro and 2000 Euro. But a high price does not always mean the best quality. For instance, our go-e Charger Gemini flex offered for €749–759 (RRP), became a price-performance winner in Auto Bild and P3 Wallbox Test in May 2023. This model is now also available with cellular connectivity for €819–829 (RRP), depending on the charging power.
Matthias H., SwitzerlandGreat functionality
I use the go-e Charger with photovoltaic panels and charge my car twice a week. The functionality is great and the whole charging process is very easy to see and adjust in the app.
Rainer M., GermanyThe go-e Charger is an excellent choice
Our two Renault Zoe's are charged via clever-PV, which controls the go-e Charger, feeding out cars with solar energy. I find go-e a very good choice because of the wide range of functions and setting options in the wallbox.
Kai W., GermanyThe go-e Charger has a perfect price-performance ratio
I charge my electric car mostly with surplus energy from my PV panels. Sometimes I set a charging time limit in the go-e app, and sometimes a kWh limit whichever suits me better. The go-e Charger has a perfect price-performance ratio and offers a lot of flexibility, which is why I chose it.
