When installing or migrating a charging station, you might hear about the P1 port. But what exactly is this mysterious port, and why is it so important to keep it open? No worries—we’ll explain it in simple terms.

What is the P1 port?

The P1 port is a special connection on your digital meter. Think of it as a small gateway that allows your charging station (or other smart devices) to communicate with your meter. This enables your charger to know exactly how much power is available and charge in the most efficient way.

Why should the P1 port be open?

Simple: without an open P1 port, your charging station cannot receive real-time data about your energy consumption. This means it operates "blindly" and cannot optimize charging based on your energy usage. This can lead to issues such as:

  • Less smart charging – Your charger cannot anticipate peaks and dips in your energy consumption.
  • Risk of overload – Without this data, your charger doesn’t know how much electricity other appliances in your home are using, which can cause problems.
  • Inefficient use of solar energy – Do you have solar panels? Then your charger won’t be able to detect when free solar energy is available. A missed opportunity!

How to open your P1 port?

Good news: it’s usually very simple. With most grid operators (such as Fluvius in Belgium), you can activate the P1 port through their online customer portal. Just log in, enable the P1 port, and you’re good to go!
