Charging a Wallbox with Photovoltaics – E-Car with Solar Power
Share
Why Charging with Solar Power Makes Sense
More and more households are combining a photovoltaic system with an electric car.
The self-generated solar power can be used directly to charge the vehicle.
This offers several advantages:
• Lower electricity costs
• Greater independence from the electricity market
• Use of renewable energy
How Charging with Photovoltaics Works
A PV system produces electricity during the day. If this electricity is not
fully consumed in the household, a surplus is generated.
This surplus can be used for:
• Household appliances
• Heat pumps
• Wallboxes
This ensures optimal use of self-generated electricity.
What PV Surplus Charging Means
With surplus charging, the electric car is only charged when surplus
solar power is available. This prevents the need to draw electricity from the grid.
Energy Management Optimizes Charging
An energy management system can automatically detect when solar power is available.
The wallbox is then automatically activated and uses the surplus electricity.
