Want to charge quickly at home without worrying about the capacity of your grid connection? An EV charger for your home lets you recharge your electric car quickly. Dynamic load balancing keeps your household electricity consumption within safe limits.

In this article, we explain what an 11 kW 3-phase charging station means for you and when to choose a three-phase connection. We also explain how to save with dynamic tariffs and by charging with your own solar panels.

We develop and manage both the hardware and software ourselves. This helps everything work seamlessly together, from the charger’s electronics to the BlueBird Power app.

What is an 11 kW 3-phase charging station?

An 11 kW 3-phase charging station uses three phases at 16 amps per phase, or 3 × 16 A. This provides an effective balance between charging speed and efficiency.

The cable from the meter cupboard to the charging station normally contains five conductors:

  • Phase 1: brown
  • Phase 2: black
  • Phase 3: grey
  • Neutral conductor: blue
  • Protective earth: green and yellow

A compatible electric car can charge considerably faster on three phases than on a single-phase connection. An 11 kW charging station can normally operate on a common Dutch 3 × 25 A household connection when installed and configured correctly.

With up to 11 kW of charging power, many electric cars can be fully recharged overnight and easily topped up during the day.

Whether you drive many kilometres or simply want to prepare for your next electric car, an 11 kW 3-phase charging station is a practical choice for home or workplace charging.

The actual charging speed depends on the maximum AC charging power supported by your vehicle. A car limited to single-phase charging or a lower AC input will not use the full 11 kW capacity.

Stress-free charging with load balancing

Using an oven, induction hob and heat pump simultaneously can cause household electricity consumption to peak.

A charging station with load balancing helps prevent your electrical installation from becoming overloaded. Using a P1 dongle connected to the smart meter, the charging station monitors household energy consumption in real time. It then automatically adjusts the charging power.

When household electricity consumption increases, the charging station temporarily reduces its power. When capacity becomes available again, it automatically increases the charging speed.

This allows you to benefit from three-phase charging while reducing the risk of tripped breakers or an unnecessary grid-connection upgrade.

11 kW versus 22 kW: which is the better choice?

An 11 kW charging station uses 3 × 16 A and is well suited to home charging. Many electric cars charge effectively at this level. An overnight session also usually provides plenty of time to prepare the vehicle for the following day.

Some manufacturers offer charging stations rated at 22 kW or 3 × 32 A. For most Dutch homes, however, this additional capacity provides limited practical benefit.

Only some electric vehicles support 22 kW AC charging. Most Dutch household grid connections are also limited to 3 × 25 A. Charging at the full 22 kW would therefore normally require a heavier and more expensive grid connection.

By deliberately choosing 11 kW, we have developed a charging station that produces less heat and does not require components designed for 32 A charging. This helps keep the system efficient and affordable.

Charging a 75 kWh battery from 20% to 80% requires approximately 45 kWh. At a continuous charging power of 11 kW, this takes slightly more than four hours before charging losses are considered.

That is usually more than sufficient for home charging, particularly overnight.

Smarter charging with your own solar energy

With True Solar, your 11 kW 3-phase charging station adjusts its charging power to the available output of your solar panels.

When solar production is relatively low, the charging station can automatically switch from three-phase to single-phase charging. This lowers the minimum power required to continue charging and allows the vehicle to use a greater proportion of the available solar surplus.

Under suitable conditions, the proportion of self-generated solar energy can approach 100%. The actual result depends on solar production, household consumption and the vehicle’s charging requirements.

Prepared for bidirectional charging

Today, you already benefit from reliable charging and smart functions such as load balancing, True Solar and automatic charging during favourable tariff periods.

The BlueSky charging station is also designed with future bidirectional applications in mind. These could allow a compatible electric vehicle to supply energy back to your home or the electricity grid.

Availability will depend on vehicle support, applicable standards, software and the required infrastructure.

Frequently asked questions about 3-phase charging stations

Do I always need a 3-phase connection for 11 kW?

Yes. 11 kW requires a 3-phase (3×16A) connection. If you currently have a 1-phase connection, you can request an upgrade from your grid operator (for a fee). Have questions? Feel free to contact us.

Is load balancing necessary for an 11 kW 3-phase charger?

Load balancing is strongly recommended. It ensures you stay within safe limits when other high-power appliances are running, allowing you to charge as safely and quickly as possible. 

My car can only charge at 7.4 kW. Does 11 kW still make sense?

Usually, yes. It depends on whether your car charges at 1×32A (7.4 kW) or 2×16A (7.4 kW). In the latter case especially, a 3-phase / 11 kW charger is a good choice. Another advantage is future-proofing: if your next car supports 11 kW charging, you’ll already be prepared. 

Can I charge using only solar power?

Yes. In the app, you can set charging to prioritise or exclusively use your own solar energy. When solar output is low, you can define a minimum charging level to ensure your car is always ready to drive.

How do 11 kW and 22 kW compare in terms of cost and usefulness?

On paper, 22 kW is faster, but in practice it rarely is — because most cars and home connections can’t support it. For home use, 11 kW 3-phase offers the best balance between speed, cost and grid load in almost all situations.

Am I ready for bidirectional charging?

Your charging station is prepared. With bidirectional charging, an electric car can do more than just charge — it can also supply power back to your home, appliances or even the grid. While most cars don’t yet support this feature, experts expect adoption to increase over time. It may take months or even years, but with this charger, you’ll be ready when the technology becomes available.

Can I install it myself?

Any modifications in the meter cupboard must always be done by a certified installer. The rest can usually be done yourself. Want to know how? Read our guide on installing a charging station yourself.
