How does a balcony power plant with storage, zero export, a new two-way meter, and communication work?

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.

Certified components meet EEG standards, including MaStR registration assistance. The solution is tenant-friendly: Schuko plug, wireless sensors, and modular expandability. DRBO Greenenergy delivers complete packages starting from 799 euros, with a 10-year warranty on storage.

Communication takes place via Zigbee or WLAN, with remote reading for grid operators. This enables 95 percent self-consumption and savings of 400-700 euros annually.

What advantages does the DRBO solution offer in comparison?

How to install the system step-by-step?

• Step 1: Mount modules and storage with DRBO brackets on the balcony (15 min., tool-free).

• Step 2: Connect inverters with Schuko plug and pair storage via app (5 min.).

• Step 3: Install bidirectional meter (if necessary, via grid operator, cost approx. 50 €) and CT sensor at the main meter.

• Step 4: Configure zero feed-in via DRBO app: connect WLAN, calibrate consumption (10 min.).

• Step 5: Register in MaStR, start and monitor – app shows real-time data.

Who benefits in which scenarios?

Scenario 1: Tenant with home office
Problem: High daily consumption (3 kWh), no storage, 50% feed-in. Traditionally: 200 € savings/year. With DRBO: Storage stores 2 kWh, zero feed-in – 550 € savings, 90% autonomy.

Scenario 2: Family with electric car
Problem: Evening consumption 5 kWh, grid strain. Traditionally: Charging time expensive. With DRBO: Storage discharges during the day, app controls – 700 €/year saved, charging time halved.

Scenario 3: Senior apartment
Problem: Constant consumption 2.5 kWh, bureaucratic hurdles. Traditionally: Complicated billing. With DRBO: Easy installation, remote monitoring – 400 € savings, no grid problems.

Scenario 4: Large family with washing machine
Problem: Peak consumption in the evening. Traditionally: 30% loss. With DRBO: Dynamic feed-in, storage buffers – 650 €/year, 95% self-consumption.

Why is now the decisive moment to get started?

By 2030, 2 million balcony power plants are expected to be operational, with subsidies of up to 500 €. DRBO Greenenergy positions itself as a pioneer with B2B expertise for private customers. Zero feed-in protects against grid fee increases (projected up to +20%). Act now for long-term independence.

FAQ

How exactly does zero feed-in work?
A CT sensor measures consumption, the inverter adjusts production – surplus goes into storage, nothing into the grid.

Do I always need a bidirectional meter?
No, but it is recommended for transparency; compatible with old meters according to Solar Package I.

Is the installation tenant-friendly?
Yes, plug & play without drilling, done in 30 minutes – no permit required up to 800 W.

Which app does DRBO Greenenergy use?
A user-friendly WLAN app with real-time data, consumption analysis, and remote control.

How realistic are the savings?
400-700 €/year with 2-4 kWh storage, depending on solar radiation and consumption.

Can I expand the system?
Yes, modular up to 5 kWh, compatible with additional modules.
