DRBO Greenenergy offers this storage unit as a practical addition to balcony power plants to drive decentralized energy transition. What is the current state of the industry? The solar energy sector in Germany is growing rapidly: In 2025, over 18 gigawatts of new PV capacity were installed, a significant portion of which came from balcony power plants. According to the Federal Network Agency, these systems now account for 15% of decentralized electricity generation. Nevertheless, self-consumption without storage remains at only 30-40%, as surplus electricity flows into the grid. What are the pain points in the energy sector? Households lose revenue from feed-in tariffs, which are less than 8 cents/kWh, while grid electricity costs 30-40 cents/kWh. The Federal Network Agency reports rising EEG surcharges, which could increase to 40% of the electricity price in 2026. Many users lament the lack of storage capacity, which leads to dependence on the grid during volatile solar production. Why is there a lack of storage solutions? Traditional households only store 20% of PV energy, as shown by a study from Fraunhofer ISE. For balcony power plants, this drops to under 10% without storage. DRBO Greenenergy addresses this with solutions like the Marstek Venus D, which increases self-consumption to up to 90%. What are the shortcomings of traditional solutions? Classic storage systems require electrician installations costing €1,000-2,000 and are not weatherproof.

As of May 2024, the maximum output of a balcony power plant in Germany is 800 watts at the inverter. Solar modules can be dimensioned higher to achieve optimal yields. This limit applies per household and allows for simplified registration without grid operator approval. (58 words) What is the maximum permissible power? The legal limit for balcony power plants is 800 watts of feed-in power. This regulation was adjusted by an EU directive in May 2024. Inverters automatically limit the feed-in to this maximum power, while solar modules can have a higher peak power of up to 1200 watts. Such systems are considered non-grid-relevant, which is why no approval from the grid operator is required. One system per household is permitted to prevent misuse. DRBO Greenenergy offers suitable sets with 800-watt inverters that meet these requirements. By increasing the power from 600 to 800 watts, the annual yield can be increased by up to 30 percent. Table: Comparison of the old and new power limits Power Level Feed-in (W) Annual Yield (kWh) Amortization (Years) Until 2024 600 500–600 5–6 Since 2024 800 700–900 4–5 These values are based on average solar radiation in Germany and an electricity price of 30 cents/kWh. Why was the power increased to 800 watts? The increase to 800 watts was implemented as part of the amendment to the Low Voltage Connection Ordinance in May 2024. The aim of this measure was to promote renewable energies while simultaneously protecting the electricity grid. According to EU Directive 2016/631, systems with a power output below 800 watts are classified as minor. This change responds to the increasing demand for balcony power plants, especially in rented households, and simplifies bureaucracy. DRBO Greenenergy has already implemented this step and, with its plug-and-play solutions together with SunLit storage units, offers the possibility to optimally utilize the increased yield. How does power limitation work? The power limitation is controlled by the inverter, which limits the feed-in to a maximum of 800 watts, regardless of the module power. Surplus electricity exceeding this limit is either throttled or redirected to the storage unit. This protects the grid from overloads. Modern devices from DRBO Greenenergy use bidirectional inverters that enable app monitoring. Solar modules with 400 watts peak power (two units) generate more when needed, but only feed in a maximum of 800 watts. Storage solutions ensure that the self-consumption rate of more than 70 percent is achieved. Which modules are suitable for the 800-watt limit? Recommended modules for balcony power plants with 800 watts are two modules of 400–600 watts peak (Wp) each. This configuration ensures a high yield rate even in diffuse light conditions. A total module power of up to 1200 Wp is therefore common. DRBO Greenenergy offers complete sets that include high-quality monocrystalline solar modules and powerful Deye inverters. This combination ensures amortization within 4 years with an annual yield of 800 kWh. Pay attention to VDE-certified components to ensure maximum safety. How do I register an 800-watt balcony power plant? Registering an 800-watt balcony power plant is very simple via the Market Master Data Register (MaStR). Registration usually takes only 10 minutes, and no grid operator registration is required. For registration, you only need the serial numbers of the inverter and the solar modules. DRBO Greenenergy offers detailed instructions and templates that further simplify the process. Tenants often only need their landlord's consent and no electrician's inspection. Can I install multiple balcony power plants? Only one balcony power plant with a maximum feed-in of 800 watts is permitted for each household meter. If multiple systems are installed, they count as one large system and require special permits. Exceptions only exist for multi-family houses with separate meters. DRBO Greenenergy recommends using a central 800-watt system with storage for maximum efficiency. What is the yield at maximum power? With a maximum feed-in of 800 watts, you can generate between 700 and 900 kWh of electricity annually, depending on your location and the orientation of the solar modules. In southern Germany, up to 1000 kWh is also possible. DRBO Greenenergy, with its integrated storage solutions, offers an increased self-consumption rate and thus increases profitability.

Zero feed-in for balcony power plants means that the generated solar power is consumed directly in the household, without being fed into the public grid. This maximizes self-consumption and helps save energy costs. Especially in conjunction with storage units like those from DRBO Greenenergy, electricity consumption can rise to over 90 percent of self-sufficiency. (58 words) What exactly does zero feed-in mean? Zero feed-in means that no solar power flows into the public grid. The inverter precisely regulates the solar system's output to match the current electricity consumption in the household. No surpluses are generated, so no electricity is wasted and no remuneration is received from the grid. This system is particularly suitable for tenants who want to reduce their energy costs without getting into conflicts with grid operators. The technology is based on a smart metering system that records electricity consumption in real time. The inverter then adjusts the generated output of the solar system to precisely meet the household's electricity demand. With storage units like those from DRBO Greenenergy, efficiency can be further increased by storing surplus electricity and retrieving it when needed. Is zero feed-in allowed for balcony power plants? Yes, zero feed-in is fully permitted in Germany. Small systems with an output of up to 800 watts generally do not require registration with grid operators, as long as no electricity surpluses are fed into the grid. This regulation also applies to rental properties, making it an attractive option for tenants. For larger systems that generate more than 800 watts, approval from the grid operator is required. The VDE standards and the Renewable Energy Sources Act (EEG) promote the use of self-generated electricity and enable households to benefit from this technology without additional bureaucratic hurdles. How does zero feed-in work technically? Zero feed-in is based on dynamic power regulation by the inverter. A current sensor continuously measures household consumption, and the inverter immediately adjusts the solar system's output. If consumption decreases, the solar system's output is automatically reduced to provide only the necessary energy. Modern inverters like DRBO Greenenergy's Deye models are specially designed for this technology and enable precise control. In conjunction with an energy storage unit like DRBO Greenenergy's SunLit, surplus electricity is stored and can be used at a later time, further maximizing self-consumption.
