registration service

We register your balcony power plant for you

In order to be able to put your plug-in solar system into operation in Germany, two registration procedures must be completed. On the one hand the registration with your network operator and on the other hand the registration in the market master data register. For both processes, we offer you support for all systems up to an output of 600 watts. After purchasing your system, we ask you to register with us using your order number and postal code. We will then guide you step by step through the registration process.

Everything at a glance

Would you like to register your own balcony power plant and become the operator of a mini solar system?


With a mini solar system, you generate green electricity on your balcony or other suitable place and feed it into the home network. In Germany it is necessary to register your balcony power plant and to take further steps. Here is an overview of the necessary sub-steps:



  • Registration of the balcony power plant with the grid operator.

  • Installation of a bidirectional counter (existing counters with a backstop are often accepted).

  • Additional registration of each mini-PV system in the market master data register of the Federal Network Agency.

We know these steps may seem tedious at first, but don't worry! With a mini solar system from Balkonvolt and the inverter used with a maximum output of 600 watts, you have the option of registering your balcony power plant in a simplified manner. This means less bureaucracy for you so that you can concentrate fully on your new system.


Want to save time with simplified login and registration? We'll gladly assist you! The only requirement is that your network operator is stored in our database. Simply enter your zip code in our contact form with the subject: REGISTER ONLINE to find out quickly whether the simplified registration for your balcony power plant is possible.

So you want to register your balcony power station - that's great!

In order to get an overview of the required documents, it is first important to find out which network operator is responsible for approving your registration. Note that your grid operator does not necessarily have to be your electricity supplier, as these are often different contacts. Since April 2019, it has been easier to register a mini solar system with the grid operator. If the grid operator does not offer simple registration, you can use the sample letter from Deutsche Gesellschaft für Sonnenenergie e. V. in connection with the commissioning protocol E.8 according to VDE AR-N-4105-2018:11. The registration of your balcony power plant also works with this.

As soon as you have determined your network operator, you must provide him with a number of documents so that he can guarantee the security of supply of the network technology. You need the following documents to register your balcony power plant: the one- to two-page registration form from your local grid operator, a unit certificate and the so-called NA protection.

The simplified registration with the grid operator often enables you to claim the feed-in tariff for solar devices. "Sounds good!" you might think. However, claiming the feed-in tariff is associated with obligations that can make the offer unattractive. A balcony power plant and every other mini PV system from Balkonvolt feeds a maximum of 600 watts into the grid of your house thanks to the inverter output of our sets. Our systems are designed to cover the electricity needs of the household, so you benefit indirectly from your balcony power plant. It helps reduce your electricity bill by using the solar power yourself.


Our recommendation: waive the right to feed-in tariffs by indicating this when registering. This is how you secure some advantages for the operation of your balcony power plant:



  • You do not have to deal with the tax office.
  • You receive a higher indirect payment through your own consumption of the solar power.

  • There is no additional paperwork.


By waiving the feed-in tariff, you gain flexibility and save yourself the hassle of administrative work. If you have any questions or need support, we will be happy to assist you and help you find the best solution for your balcony power plant.

Goodbye mains operation, hello balcony power plant!

When you register with the network operator, your meter may also be changed at home. Unfortunately, your old electricity meter without a backstop cannot be retained, as it is only designed for measuring electricity in one direction. In a conventional one-way system, the electricity flows from the public grid in the direction of your home power grid. In the case of the old Ferraris counters with rotating disks, this can lead to legal consequences, as the records could be falsified by turning them backwards. They are therefore not suitable for connecting a small PV system.


Instead, you need an electricity meter with a backstop or a bidirectional meter. Many are not aware that by 2032 modern metering systems such as bidirectional meters must be installed by the local grid operator by law. Therefore, there are usually no exchange costs for you as a user.

Please note: In addition to a bidirectional meter (or electricity meter with backstop), some network operators also provide a suitable energy connector according to the VDE V 0628-1 standard. A conventional Schuko plug, which is used by many households to operate mini-PV systems, is not considered suitable by the grid operator. However, the network operators cannot make any specific requirements for the choice of plug device, so the decision on the plug type is entirely up to you. We will be happy to assist you and advise you on the appropriate plug-in devices for your balcony power plant.

As soon as you have successfully registered with your network operator: Plug in and save!

After you have successfully registered your balcony power plant, nothing stands in the way of environmentally friendly power generation with your solar system. You don't even need an electrician to install your mini photovoltaic system, thanks to the easy installation system from Balkonvolt. You become an electrician yourself: simply attach the modules to a suitable location, such as your balcony, and connect them to the inverter. Then simply plug the Wieland or Schuko plug into the associated socket and you're ready to go. From now on, the focus is on the advantages of your new mini solar system!

As a rule, you should register with the Federal Network Agency no later than one month after your balcony power plant has been commissioned. If you choose to do this yourself, it takes approximately 20 minutes and can be done either in person or through an authorized person. In the first two steps, general and personal data are requested from the BNetzA. This is followed by the actual registration of the balcony power plant: Information such as the number and total output of the modules, the output of the inverter and information on the location of the system are important here.


With a plug & play solar system, you can all make a contribution to the energy transition. Regardless of whether you are a tenant or a homeowner: Our offers are aimed at everyone who dreams of a sustainable future. Are you there too?
