Information

In 2025, electricity prices in Germany will rise to an average of 40 cents per kWh, while balcony power plants enable up to 70 percent self-consumption and save 300 to 600 euros annually. DRBO Greenenergy offers complete plug-and-play solutions with storage and bidirectional inverters that guarantee zero feed-in. These systems make tenants and homeowners independent of the grid and use smart communication for maximum efficiency. What challenges exist in the balcony power plant industry? The energy transition is progressing, but private households are struggling with rising costs: According to the Federal Network Agency, electricity consumption in 2025 amounted to 500 TWh, with 30 percent of households consuming more than 4,000 kWh annually. Many users report high grid fees due to unused feed-in. DRBO Greenenergy addresses this with storage solutions that store surplus electricity instead of wasting it. Grid operators are increasingly demanding separate billing for feed-in and consumption, leading to conflicts. In 2024, over 500,000 balcony power plants were registered, but only 20 percent use storage for zero feed-in. Without smart meters, users lose up to 50 percent of their solar power to unnecessary feed-in. Tenants and owners often fail due to bureaucratic hurdles: registration in the MaStR takes weeks, and missing communication modules prevent real-time monitoring. This leads to unnecessary costs of 100 to 300 euros per year due to inefficient use. Why do traditional solutions fail? Traditional balcony power plants without storage feed up to 40 percent of electricity into the grid, without remuneration above 8 cents/kWh. Simple inverters lack dynamism and do not adjust production to consumption. DRBO Greenenergy surpasses this with modular storage and Deye inverters for precise control. Older meters allow reverse operation, but since Solar Package I 2024, VDE standards recommend bidirectional meters for transparency. Without communication, remote reading is missing, complicating annual billing. Traditional systems achieve only 30 percent autonomy, while smart alternatives achieve 80 percent. Retrofitting costs – up to 500 euros – are a deterrent, and installation requires an electrician. DRBO Greenenergy minimizes this with plug-and-play packages with integrated communication. What is DRBO Greenenergy's solution? DRBO Greenenergy offers balcony power plants with storage for zero feed-in, compatible with new bidirectional meters and WLAN communication. Key features include bidirectional Deye inverters (800 W), storage capacities of 1-5 kWh, and real-time monitoring via app. The system dynamically adjusts production to household consumption, stores surplus, and discharges when needed.

The Marstek B2500 is a flexible balcony power storage unit that can be operated with up to four solar modules, significantly increasing self-consumption. This connection diagram for 4 modules shows how to optimally use surplus energy – plug-and-play, without an electrician. Current Challenges in the Balcony Solar Industry In Germany, electricity prices rose sharply in 2025, while demand for balcony power plants grew strongly. However, many users lose a large part of the solar energy generated because surpluses flow unused into the grid – this is where a storage unit comes in. Important: There is no feed-in tariff for balcony power plants; the advantage comes from self-consumption. Why do many fail at self-consumption without storage? Without a storage unit, self-consumption from balcony power plants is often below 40%, as production and consumption are not synchronized. In winter months, generation drops sharply. A storage unit makes the electricity generated during the day usable in the evening. What solution does the Marstek B2500 connection diagram for 4 modules offer? The Marstek B2500 (LiFePO4) supports up to 1,600 W PV input and 800 W output. For 4 modules (e.g., 400 Wp each), the connection is made in parallel with Y-cables to the two MPPTs. The app enables real-time monitoring and zero export. Suitable MC4-compatible T-connectors are suitable for parallel wiring. Marstek B2500 vs. Traditional Storage Units Criterion Traditional Storage Units Marstek B2500 Installation Electrician, 2 hours Plug & Play, 15 minutes Capacity fixed, approx. 2 kWh modularly expandable Efficiency 80–85% approx. 95% with MPPT Cycles 2,000–3,000 over 6,000 Weather Protection IP20 IP65, -20 °C to +60 °C How do I connect the Marstek B2500 with 4 modules?
