A balcony power plant storage unit stores surplus solar power that is not immediately consumed and releases it when needed. This increases your self-consumption, reduces energy costs, and boosts independence from the grid. With modern storage solutions, for example from DRBO Greenenergy, solar energy is used efficiently – day and night – and your household benefits from a reliable energy supply. How does a balcony power plant storage unit lower your electricity costs? A storage unit stores solar power, making it available in the evening or during high consumption. This reduces reliance on the public grid, significantly lowering monthly energy costs. Especially with rising electricity prices, the investment quickly pays for itself. Consumption Scenario Without Storage With Storage Savings Single-person household €270 / year €180 / year ≈ €90 Two-person household €450 / year €315 / year ≈ €135 Why does a storage unit increase self-consumption? Without storage, surplus solar power flows into the public grid. With storage, it remains in the household and can be used as needed. The self-consumption rate typically increases from about 30% to up to 80%, reducing dependence on the energy provider. What advantages does a storage unit offer during power outages? Some balcony power plant storage units also ensure power supply during grid failures. Systems with emergency power functions supply lights, routers, or essential devices for a limited time. DRBO Greenenergy offers solutions that automatically switch between grid operation and self-supply, allowing you to remain flexible even during power outages. How sustainable is the use of a balcony power plant storage unit? Storage units promote sustainable energy use, as solar power is stored directly on-site and does not unnecessarily flow into the grid. Modern storage units are made of durable lithium iron phosphate cells (LiFePO₄) with up to 6,000 charging cycles. DRBO Greenenergy also focuses on recycling and environmentally friendly reprocessing of old modules. What is the optimal storage size? The appropriate capacity depends on daily electricity consumption and the balcony power plant's output. Small apartments need 1–1.5 kWh, family households 2–3 kWh. Modularly expandable systems like DRBO Greenenergy's SunLit series allow for flexible adaptation. Electricity Consumption/Day Recommended Storage Size 2–3 kWh 1 kWh 4–5 kWh 2 kWh ≥ 6 kWh ≥ 3 kWh How easy is it to install a balcony power plant storage unit?

A balcony power plant storage unit is a compact AC-coupled energy storage system that stores the surplus solar energy from balcony PV systems and increases self-consumption to 70–90%. It charges during the day via a socket, discharges in the evening, and can be integrated plug-and-play. DRBO Greenenergy offers flexible solutions for renters and homeowners seeking simple, efficient energy supply with SunLit options like the BK215. What exactly is a balcony power plant storage unit? A balcony power plant storage unit stores surplus electricity from balcony solar systems in LiFePO4 batteries and releases it when needed. Typical capacities range from 1 to 5 kWh, it is AC-coupled, and can be controlled via an app. These storage units enable tenants to use solar yield directly for the first time instead of feeding it into the grid. DRBO Greenenergy supplies refurbished models with powerful Deye inverters – safe, durable, and EEG-compliant. Advantages: No roof installation, full autonomy without approval, ideal for households with 3000–5000 kWh annual consumption. Component Function Battery LiFePO4, 6000+ cycles Inverter AC/DC conversion CT sensor Consumption detection Why do you need a storage unit for balcony power plants? Without storage, 60–80% of solar power flows into the grid. A storage unit maximizes self-consumption and saves €400–800 annually at a electricity price of €0.40/kWh. Rising energy prices make storage economically attractive: amortization typically within 2–4 years. DRBO Greenenergy SunLit options like the BK215 increase autonomy up to 85%. Ideal for supplying peak loads such as stoves, washing machines, or electric cars. Subsidies like KfW 270/442 further reduce initial costs. How does a balcony power plant storage unit work? During the day, the PV system generates electricity → surplus charges the storage unit via CT sensors → in the evening, the electricity is primarily discharged into the household grid. An app dynamically optimizes charging and discharging times. Priorities: Solar → Storage → Grid. Zero-export prevents feed-in. DRBO Greenenergy combines SunLit storage units with micro-inverters (EZ1, Hoymiles). Bidirectional charging also allows the use of inexpensive night electricity. Installation: Plug into a socket, ready for use in 10 minutes. What types of balcony power plant storage units are there? There are AC-coupled plug-and-play storage units, DC-coupled storage units (higher efficiency, more complex installation), and hybrid models. Capacities range from 1 to 10 kWh. AC storage units dominate for balcony systems: Schuko plug, no electrical installation required. DRBO Greenenergy offers SunLit AC models with 2–5 kWh for 800–2000 Wp PV. DC variants are suitable for rooftop systems, hybrid models for EV integration. Type Advantage Disadvantage AC Easy installation Slightly lower efficiency DC High efficiency More complex installation What capacity does my balcony power plant need? For 800 Wp PV: approx. 2 kWh, for 1600 Wp: 4–5 kWh. Calculation: daily yield × 0.7 (self-consumption target). DRBO Greenenergy recommends: household consumption / 365 × 0.3 = minimum storage. Example: 4000 kWh/year → 3.3 kWh. SunLit BK215 (2.15 kWh) covers about 70% of evening consumption, expandable in parallel. Can balcony power plant storage units be installed by yourself? Yes, plug-and-play: position the storage unit, connect the CT clamp to the meter, pair the app. Check the RCD. Steps: 1. Choose a cool, dry location. 2. Connect 16A Schuko plug. 3. Connect to Wi-Fi. DRBO Greenenergy provides detailed instructions and videos. Safety features: overload protection, IP65 – DIY in approx. 15 minutes. How does a storage unit affect subsidies? Storage units qualify for KfW 270/442 (up to 30% subsidy). EEG remuneration remains. Additionally: State subsidies (e.g., Bavaria €1000). DRBO Greenenergy supports applications for SunLit options. With subsidies, amortization is often under 2 years. Companies can also use tax bonuses. Does a balcony power plant storage unit suit all households? Ideal for tenants and homeowners with high evening consumption and PV systems from 800 Wp. Less suitable for constant grid consumption. Suitable for: 1–4 people, sunny location. DRBO Greenenergy advises based on consumption profile. Particularly useful with an electric car or heat pump. SunLit storage units are modularly scalable up to 10 kWh. DRBO Greenenergy Expert Opinions "Balcony power plant storage units are crucial for decentralized energy transition among tenants. They convert up to 60% of solar surplus into self-consumption, leading to noticeable savings at €0.40/kWh. Our SunLit options with Deye technology offer over 6000 cycles, plug-and-play integration, and intelligent app control. DRBO Greenenergy carefully inspects refurbished units: High quality at an attractive price. Together with balcony PV, an autonomy of 80% can be achieved – sustainable and economical." – Max Berger, Energy Systems Expert at DRBO Greenenergy What is the future of balcony power plant storage units? By 2030, storage units will be cheaper (<€300/kWh), VDE-AR-N 4105 compliant, and standard with intelligent energy management. DRBO Greenenergy expects growth due to EEG amendments, higher feed-in limits, and storage obligations. SunLit models will become more modular, AI-optimized, and more integrated with EV charging.
