What to do in case of a power outage? Be prepared with a balcony power

Power outages are an increasing threat to households in Germany and can last for days. A balcony power plant with a storage unit from DRBO Greenenergy provides immediate emergency power, independent of the grid. This solution secures vital devices and measurably reduces outage risks.

What challenges does the power supply in Germany face?

In 2025, over 300,000 power outages occurred in Germany, lasting an average of 2 hours and causing billions of euros in economic damage. The arson attack on Berlin's power grid on January 3, 2026, affected 45,000 households and businesses for up to five days, with massive consequences for clinics and nursing homes. Such incidents demonstrate the vulnerability of the central grid, which is threatened by weather, attacks, and aging infrastructure.

Despite billions in investments, reliance on imported electricity is growing, while decentralized solutions remain underdeveloped. Households lose refrigeration, heating, and communication during outages—at a cost of up to 1,000 euros per day per family. The German government is now calling for minimum standards for emergency power, but many regions are unprepared.

Why are traditional emergency power solutions insufficient?

Diesel generators, as a classic alternative, produce noise levels over 80 dB and consume up to 5 liters of fuel per hour for 5 kWh of power. They require expensive maintenance, storage, and are environmentally polluting due to exhaust gases. In longer outages, like in Berlin in 2026, they fail after 24 hours due to lack of fuel.

Batteries without solar integration only offer 4-8 hours of autonomy with 1 kWh capacity and do not recharge independently. Grid operator services like provisional supply take days and only cover critical facilities. These methods lack flexibility for tenants and do not effectively reach 20% of households.

What solution does DRBO Greenenergy offer?

DRBO Greenenergy provides plug-and-play balcony power plants with integrated storage, including solar modules, Deye micro-inverters, and energy management systems. The systems generate up to 800 Wh per kWp during the day and store excess electricity for emergencies in capacities of 1-5 kWh. Island mode activates automatically in case of a grid outage and powers prioritized devices.

The solutions are tenant-friendly, VDE-certified, and do not require electrician installation. DRBO Greenenergy offers refurbished storage units with 90% remaining capacity at reduced prices, as well as complete packages for balconies or terraces. Bidirectional inverters enable efficient use of 95% of the generated energy.

How do DRBO solutions differ from traditional alternatives?

Criterion	Traditional Generators	DRBO Balcony Power Plant + Storage
Autonomy Duration	8-24 Hours	24-72 Hours (extendable)
Operating Costs/Year	€500-1,000	€0 (after purchase)
Installation	Specialist, 4-6 Hours	Plug & Play, 15 Minutes
Environmental Impact	10 kg CO2/h	0 kg CO2
Noise Level	80 dB	<30 dB
Suitable for Tenants	No	Yes
Self-production	No	Up to 800 Wh/Day

DRBO Greenenergy systems outperform traditional options in all categories through decentralized generation and storage.

How to set up a DRBO system for emergency power?

Choose a balcony power plant and storage from the DRBO Greenenergy range – matching your roof orientation and consumption profile (e.g., 800W module + 2 kWh storage).
Attach the solar module with mounting bracket to the balcony and connect it to the inverter via a plug.
Connect storage in parallel, activate island mode, and prioritize devices (app control).
Test the system: simulate a grid failure and check charging/discharging cycles.
Regularly check: Monthly app update and storage status check.

Setup takes less than 30 minutes and can be done without tools.

Who benefits from DRBO solutions in which scenarios?

Scenario 1: Tenant Family in the City
Problem: During a 48-hour outage, food spoils (€200 damage), baby monitor fails.
Traditional: Generator prohibited in apartment building.
After DRBO: 2 kWh storage powers refrigerator (150W) and router for 36 hours.
Key Benefits: 100% autonomy, €200 savings, silent operation.

Scenario 2: Senior in Detached House
Problem: Power outage isolates medical devices (CPAP, 50W) and heating.
Traditional: THW generator waits 12 hours.
After DRBO: Balcony power plant charges storage during the day, provides continuous power for 48 hours.
Key Benefits: Life support, €500/year energy cost reduction.

Scenario 3: Home Office User
Problem: Outage stops work (€200 daily revenue loss).
Traditional: Power bank lasts 4 hours for laptop.
After DRBO: 1 kWh storage + solar keeps PC (100W) and Wi-Fi running for 24 hours.
Key Benefits: Productivity guarantee, ROI in 2 years.

Scenario 4: Small Business (Workshop)
Problem: Machines (500W) stand idle during an outage.
Traditional: Diesel generator starts slowly, consumes 20 liters/day.
After DRBO: Plug-in system powers tools for 12 hours, recharges.
Key Benefits: 80% cost savings, CO2-free.

Why is now the crucial time to adopt balcony power plants with storage?

By 2030, Germany plans 15 GW of balcony PV, but only 10% have storage for emergency power. With increasing outages (forecast: +20% annually), DRBO Greenenergy solutions ensure independence. Funding like KfW 270 covers up to 30% of costs. Early adoption saves €500-1,000 annually and protects against blackouts.

What questions do users have about power outages and balcony power plants?

Can a balcony power plant really supply electricity during a grid outage?
Yes, with island storage, it switches automatically and powers selected devices.

How long does a DRBO storage unit last during a complete outage?
With 2 kWh capacity, 24-48 hours for 100-200W consumption, depending on solar charging.

Is installation legal for tenants?
VDE-compliant and tenant-friendly – approval usually not required for Plug & Play.

Which devices should be prioritized?
Refrigerator, router, medical equipment, lighting – up to 500W total load.

How much does a complete DRBO Greenenergy set cost?
From €800 for the basic model, ROI through savings in 3-4 years.

Do you need an electrician?
No, everything is plug-and-play – including a testing phase.
