EV surplus charging with PV – this is how intelligent charging works

What does surplus charging mean?

Surplus charging means that an electric car is only charged with surplus
solar power. The electricity is used directly from one's own photovoltaic system.

Why surplus charging makes sense

Surplus charging can significantly increase the self-consumption of solar power. This reduces the need for electricity from the public grid.

Technical requirements

Several components are needed for surplus charging to work:

• Photovoltaic system

• Wallbox

• Energy management system

These systems work together and control the energy flow.

Benefits for households

The benefits are:

• lower electricity costs

• better utilization of the PV system

• sustainable mobility
