Home Wallbox Installation: Costs, Process & Registration

Do you drive an electric car and want to charge conveniently and cheaply at home? Then your own wallbox is the best solution. Here you will learn what you need for a home wallbox installation, what it costs, which registration is mandatory and how to charge your car with your own solar power. PVPro Solar installs wallboxes in Hanover and Lower Saxony, on request together with your PV system.

Home Wallbox Installation: Key Facts at a Glance

Why a Wallbox Instead of a Household Socket?

A wallbox is a charging station for electric cars that is permanently mounted on the wall. It usually charges at 11 kW, many times faster than a household socket, and is designed for the continuous load of charging. A normal socket is not made for this and should only be an emergency solution. With a home wallbox installation you start every morning with a full battery, and with a PV system on the roof you charge a large share with your own solar power.

What Does the Installation Require?

• Three-phase connection: 11 kW needs a three-phase supply, which most single-family homes have.
• Sufficient house connection capacity: for an 11 kW wallbox this is usually enough in single-family homes. For 22 kW, the grid operator checks whether the connection can handle the load.
• Meter cabinet and protection: every wallbox needs its own circuit breaker and protection against AC and DC fault currents: either a type B RCD, or a type A RCD combined with DC fault-current detection, which many wallboxes already have built in.
• Location: usually garage, carport or house wall, as close as possible to the distribution board so the supply cable stays short.
• Tenants and owners’ associations: since the 2020 reform, flat owners (Section 20 WEG) and tenants (Section 554 BGB) generally have a right to have a charging point installed; the costs are usually borne by whoever wants it.

Registration with the Grid Operator: What Is Mandatory?

Under Section 19 of the Low Voltage Connection Ordinance (NAV), every wallbox must be registered with the grid operator before commissioning; registration is free. Charging stations above 12 kVA, typically 22 kW wallboxes, additionally need the grid operator’s approval before installation. That is why we recommend an 11 kW wallbox for most households: it is enough to fully charge an electric car overnight and can be installed without an approval procedure.

Since 2024, Section 14a of the Energy Industry Act (EnWG) also applies: new wallboxes must be controllable. The grid operator may temporarily limit charging to 4.2 kW if the grid is at risk of overload, so charging is always still possible. In return you pay a reduced grid fee; with the flat-rate option (module 1), usually about €110 to €190 a year depending on the grid operator. Power from your own PV system is not affected by the throttling. We handle the registration and technical requirements for you.

Home Wallbox Installation: How It Works

1. On-site visit: we check the house connection, meter cabinet, mounting location and cable route.
2. Choosing the wallbox: matched to your car, your charging habits and, if you have one, your PV system.
3. Registration with the grid operator under Section 19 NAV and setting up controllability under Section 14a EnWG.
4. Laying the supply cable from the distribution board to the mounting location, with the correct cable cross-section.
5. Mounting, protection and connection in line with DIN VDE 0100-722.
6. Commissioning: test report, test charge and introduction to the app.

The installation itself usually takes half a day to a full working day. Important: only a qualified electrician may carry out the installation; self-installation is not permitted.

What Does a Home Wallbox Installation Cost?

The costs consist of the device and the installation. According to the German automobile club ADAC, typical ranges for a single-family home are:

It is cheapest when the garage or carport is right next to the house and the meter cabinet has enough space. Long cable runs, groundwork or a new meter cabinet increase the cost. If you have a PV system installed at the same time, you save effort because the meter cabinet and planning are handled in one step. You receive your fixed price in writing after the on-site visit.

Installation by Our Own Electricians

We plan and install your wallbox with our own certified electricians in line with DIN VDE 0100-722, including protection, supply cable and test report. You receive the exact price for your cable route and meter cabinet as a fixed price after the on-site visit.

Registration and Section 14a Taken Care Of

We register the wallbox with the grid operator, usually enercity Netz or Avacon in the Hanover region, and set up controllability under Section 14a EnWG so you get the reduced grid fee.

Together with a PV System, Battery and Heat Pump

On request, we integrate the wallbox into your existing or new PV system, with a Fronius inverter and BYD battery, and plan it together with a heat pump. That way you have one contact for the charging station, solar system, battery and heating.

Which Wallbox Suits You?

• Basic wallbox (11 kW): charges reliably without extra functions. Enough if you have no PV system.
• Smart wallbox (11 kW): with app, load management and an interface to energy management. The right choice if you want to charge with surplus PV power.
• Bidirectional wallbox: can feed power from the car battery back into the house. Technically exciting, but much more expensive and so far usable with only a few vehicles.

Almost all electric cars in Europe charge via the Type 2 plug, which all common wallboxes support.

Wallbox and PV System: Charging with Your Own Solar Power

With a PV system, a wallbox becomes truly economical. With surplus charging, the energy management continuously measures how much solar power is currently left over and passes exactly that power to the wallbox. We combine this with Fronius inverters and a BYD battery if you also want to charge with solar power in the evening.

An example: driving around 15,000 km a year at about 20 kWh per 100 km needs around 3,000 kWh of charging power. An 8 kWp system in the Hanover region generates around 7,100 kWh a year, part of which can be charged directly into the car, especially if the car is at home during the day or at weekends. How large your PV system should be for car and household, and how phase switching works with surplus charging, is explained under photovoltaics with heat pumps and wallboxes.

Are There Subsidies for Wallboxes?

The former KfW grants for private charging stations have ended, and there is currently no nationwide funding programme for private wallboxes. Some cities, municipalities or energy suppliers offer their own grants from time to time, so it is worth checking before placing an order. The reduced grid fee under Section 14a EnWG, on the other hand, has a lasting effect. You can also claim the labour costs of the installation as tradesperson services in your tax return: 20% of the labour costs, up to €1,200 a year (Section 35a EStG). This only covers labour, travel and machine costs, not the device, and only if you pay by bank transfer against an invoice. By the way, the zero VAT rate for PV systems does not apply to the wallbox. If the wallbox is planned together with a PV system, you also benefit from solar power, which is much cheaper than grid electricity. All funding options around photovoltaics are listed under solar subsidies in Germany.
