Register a balcony power plant and become an operator.

With a mini solar system you generate your own green electricity on the balcony and Co. and feed it into the house network. In order for you to be able to do this in Germany, you have to register your balcony power plant and take other precautions. This includes the following sub-steps:



  • First, the balcony power plant is registered with the grid operator.

  • Then a bidirectional counter should be installed (existing counters with a backstop are often accepted as well).

  • For each mini-PV system, there is an additional registration in the market master data register of the Federal Network Agency.

Sounds annoying, but just the peace. A mini PV system from priwatt has a special feature thanks to the inverter used with a maximum output of 600 watts: you have the option of registering your balcony power plant in a simplified manner. For you, this means that you have to deal with less bureaucracy and can concentrate fully on your new system.


Would you like to save yourself the time for the simplified login and registration? We support you with this. The only requirement: Your network operator must be stored in our database. Simply enter your zip code in our registration service and you'll know!

Register your balcony power plant, black and white.

So you want to register your balcony power plant - so far so good. In order to get an overview of the documents to be submitted, you must first find out which network operator is responsible for you and for approving your registration. Keep in mind that your network operator is not necessarily your electricity supplier, because these are often different contact persons. Since April 2019, it has been easier to register a mini solar system with the grid operator. If he does not offer the simple registration, you can use the sample letter from the 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.

Once you have found your network operator, you must send him some documents so that he can ensure 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.

Who renounces, wins.

The simplified registration with the grid operator often brings up another aspect: claiming the feed-in tariff for solar devices. "Sounds good!" you might be thinking. Claiming the feed-in tariff, however, comes with obligations that make the offer unattractive. A balcony power plant and every other product from priwatt feeds a maximum of 600 watts into the grid at your home due to the inverter performance of our sets. Our mini PV systems are designed to cover the electricity requirements in the household, so that you benefit indirectly from your balcony power plant. Ultimately, it ensures that your electricity bill decreases through self-consumption of the solar power.


Our recommendation: waive the right to feed-in tariffs by indicating this on the registration form. This is how you secure freedom for the operation of balcony power plants that should not be neglected:


  • No dispute with the tax office

  • Higher indirect remuneration through self-consumption of the solar power

  • No additional paperwork

Goodbye mains operation, hello balcony power plant.


When you register with the network operator, you may also have to change your meter at home. Unfortunately, you cannot keep your old electricity meter without a backstop because it is only suitable for measuring current in one direction. With a common one-way system, the electricity flows from the public power grid in the direction of your home power grid. In the case of the old Ferraris counters with a rotating disc, this can have legal consequences because the records are falsified by turning them backwards. It is therefore not suitable for connecting a small PV system.

Instead, you need an electricity meter with a backstop or a bi-directional meter. What a lot of people don't know: by 2032, according to the law, modern measuring systems such as bidirectional meters are to be installed by the local grid operator anyway. For this reason, there are usually no exchange costs for you as a user.


Note: According to some network operators, in addition to a two-way meter (or electricity meter with backstop), you also need a suitable energy connector according to the VDE V 0628-1 standard. A Schuko plug, which is used by many households in accordance with the law for the operation of mini PV systems, is not suitable from the grid operator's point of view. However, they cannot make any demands on the choice of plug-in device, so the choice of plug is entirely up to you.

As soon as you register with the network operator: plug in, be the operator.

After you have been able to register 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. With the simple assembly system from priwatt, you become an electrician yourself: Simply attach the modules to a suitable location such as the balcony and connect them to the inverter. Then you just plug the Wieland or Schuko plug into the corresponding socket and off you go. From now on, the focus is on the advantages of your new mini solar system!

Step by step towards green electricity.

As a rule , registration with the Federal Network Agency takes place no later than one month after the balcony power plant has been commissioned . If you want to do this yourself, it takes about 20 minutes and can be done in person or by 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: Important here are the number and total output of the modules, the output of the inverter and information on the location of the system.


With a plug & play solar system, everyone can 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?
