Enefit Volt charging station installation guide

Welcome to the Enefit Volt installation guide! In order for the installation and use of the charger to go smoothly, it is necessary to know a few things first. This guide covers the most important issues related to installation and helps prepare you to get started with smart charging.

What is the total power available in the household?

Before installing the charger, make sure that there is enough free power for the charger in your home electrical system. Otherwise, the electrical system will not be able to cope with the increased amount of current, there will be an overload and power outages will begin to occur. You can check the size of the main fuse at your point of consumption at Elektrilevi’s self-service.

The charger requires the following amperage to charge at maximum speed:

11 kW - 5G4 – 16 A – a 3-phase 11 kW charger requires at least a 5G4 cable and 16 amperes (A). Suitable for customers who have a 3-phase car and a 16 A main fuse.

22 kW - 5G6 – 32 A – a 3-phase 22 kW charger requires at least a 5G6 cable and 32 A. Suitable for customers with a 3-phase car and at least a 32 A main fuse.

2x22 KW - 5G10 – 63 A – a 3-phase 22 kW charger for two cars requires at least a 5G10 cable and 63 A.

In a situation where there’s less current available in the electrical system, there are two options: set the limit value manually to the charger during setup or install a DLM device. For example, if you know that there is a maximum of 25 A available to the charger, we can limit the charger settings accordingly. At this point, it should be taken into account that limiting also reduces the charging speed.

In the case of a main fuse of up to 32 A and a 22 kW charger, we definitely recommend installing a DLM device. Otherwise, an overload may occur in the electrical system.

The DLM device ensures that the amount of current available to the charger is adjusted automatically based on the household’s real-time consumption. You can also be sure that the car charges at the maximum possible speed. You can find more information about dynamic load management here.

Where can you install the charger?

The next step should be mapping the exact location of the charger. The charger can be installed on the wall or fence post of the (apartment) house, on a separate support post, in the garage or even in the outbuilding.

Knowing the location of the charger makes it easier to consider the various material and equipment requirements necessary for installation.

Where is the building’s switchboard located?

When installing the charger, it is also worth taking into account its location in relation to the switchboard. Since an electric cable must be used to connect the charger and the switchboard, it is necessary to map the location of the switchboard in addition to the charger and calculate the route between the two devices.

In our opinion, it is best to install an additional switchboard in order to install the DLM device. This helps to ensure that there is space for both the DLM device and all the necessary circuit breakers (RCB, MCB). An additional switchboard comes with the installation package of the DLM device.

NOTE! The distribution board is the property of Elektrilevi and we cannot connect the charger to it. The charger is connected to the main fuse of the building.

How should the cable be routed and what should be the distance from the switchboard to the charger?

Determining the route between the charger and the switchboard will help you calculate how many metres of cable will be needed to make the connection. Although it is generally possible to visibly estimate it, it is wiser to map the entire path, taking into account all the angles along which the cable runs, just to be certain.

Our STANDARD and DYNAMIC installation packages include 15 metres of cable material, which should usually be enough. If you need more cable material, let us know and we will find a suitable solution together.

We install the cable on the ground. In order to protect it from the weather, a special tube surrounds the cable.

Is there room in the main switchboard for the cable?

For the BASIC and STANDARD installation packages, the offer does not include an additional switchboard. Ensure that there is enough space in the switchboard for the following circuit breakers:

  • residual current protection – 4 modules

  • circuit breaker – 3 modules.

If you’re not sure, send us a photo of your switchboard and we’ll help figure out the capacity.

Does the make and model of the car affect the installation of the charger and how exactly?

Enefit Volt chargers are suitable for charging all electric cars. In order to evaluate which charger is most suitable, determine the maximum AC charging rate of your vehicle. A good overview of AC charging speeds can be found in the Ev Specs comparison chart.

Depending on the car, the charging options are different. Knowing the charging requirements of your vehicle allows you to choose the most suitable home charger and ensure efficient charging.

Currently, there are more car models with a charging capacity of less than 22 kW. However, it is important to remember that when you purchase an electric car charger, it will stay with you for at least the next 10 years. That’s a long time, during which you will probably be able to replace your electric car once.

If your current electric car does not allow more than 11 kW charging, it is also possible to install a more future-proof 22 kW charger and limit the available power to 16 A.
