A renewable way to charge your own electric car with self-generated solar power has become possible thanks to future-oriented key technology. The growing trend of generating your own power coupled with the desire for electromobility is known as 'sector coupling'. The combination of an inverter, such as the KOSTAL PLENTICORE plus, and your own wallbox makes this intelligent, safe and efficient.
A clever combination: charging with solar power
Driving an electric vehicle is fun – but charging it just as ecologically and economically is a challenge. Although it is possible to run a wallbox on conventional electricity from the public grid, using self-produced solar power instead is easier on your wallet and the environment.
It is therefore well worth connecting the home charging station for your electric car with the PV system’s inverter. By using renewable PV electricity, you can charge your own electric vehicle outside your own front door or at work – an environmentally friendly, flexible and convenient solution.
How to combine a wallbox and inverter
If neither a photovoltaic system nor a charging station has yet been purchased, you can plan the ideal system with the installer. It is important that all components, such as solar modules, inverter, energy meter, battery storage and wallbox, are coordinated with one another.
The PV system with connected storage can then cover a large proportion of home consumption by means of solar power and supply the surplus solar energy via the wallbox to charge your electric car. The connected energy meter provides all the necessary information and ensures optimum wallbox operation.
Retrofitting a wallbox
If you already have your own PV system with inverter and storage, you can now cleverly add a wallbox. For perfect control, it must be possible for the new wallbox to be integrated into the existing PV system with the inverter. In addition to suitable interfaces, the charging power should be adjustable so that different charging modes are available for the wallbox and intelligent energy management is supported.
Retrofitting an inverter
If you already own an electric vehicle and wallbox and now want to add a PV system, it is important to check whether the existing wallbox can be combined with the new inverter.
This is the only way to ensure that the system consisting of wallbox and inverter can be intelligently controlled. If this is not the case, you should consider integrating a new wallbox into the complete system, which intelligently controls the charging processes of the electric vehicle with the inverter.
