How does the refurbished Edition balcony power plant storage for balcony installation work?

Jan 31, 2026

In Germany, electricity prices are continuously rising, while balcony power plants are becoming popular as a simple solution for decentralized energy generation. The refurbished Balcony Power Plant Storage Edition from DRBO Greenenergy optimizes these systems by storing surplus solar power and making it available around the clock. This measurably reduces energy costs and households achieve higher degrees of self-sufficiency – a smart investment for tenants and owners.

What is the current state of the balcony solar industry?

In 2025, over 500,000 German households will be using balcony power plants, a growth of 300 percent since 2023. According to the Bundesnetzagentur report, 2.5 billion euros are invested annually in small PV systems. Nevertheless, up to 70 percent of the generated energy remains unused as it flows into the grid during the day.

What pain points are currently burdening users?

Many households still pay bills of 800 to 1,200 euros annually despite having PV systems, as evening and night consumption is grid-dependent. The pressure of the EEG surcharge and grid fees exacerbate this: up to 40 cents per kWh are incurred. Moreover, 60 percent of systems lack storage, pushing self-sufficiency below 30 percent.

Why do traditional solutions fail under balcony conditions?

Battery storage for full PV systems costs 5,000 to 10,000 euros and requires roof installation and an electrician. They are not suitable for balconies: too large, too heavy, not tenant-friendly. Plug-and-play alternatives without storage ignore evening peaks, with self-consumption rates below 40 percent.

What is missing from conventional storage options?

Large storage systems have efficiencies of 85-90 percent but high standby losses of up to 20 watts. Installation takes days, permits months. In comparison, a pure balcony power plant wastes 50-70 percent of its potential without storage.

What is the refurbished Balcony Power Plant Storage Edition from DRBO Greenenergy?

This storage system stores 2,016 Wh from balcony power plants via a Deye micro-inverter (model MH7A-48, refurbished Edition). It charges during the day with up to 800 Wp PV power and discharges when needed with 96 percent efficiency. DRBO Greenenergy offers plug-and-play with app monitoring for iOS/Android, IP65 protection, and includes MC4 cables. The refurbished variant reduces costs by 30 percent while maintaining full functionality.

What core functions make DRBO Greenenergy special?

Modular expandability up to 8 kWh, bidirectional inverter for grid/battery use. Energy management system prioritizes self-consumption, minimizing grid feed-in. DRBO Greenenergy integrates TÜV-certified Deye technology for a 10-year lifespan and 30-year performance guarantee.

Why does this solution surpass traditional storage systems?

Criterion	Traditional Large Storage Systems	Refurbished Edition DRBO Greenenergy
Acquisition Costs	€5,000–10,000	€1,000–2,000 (refurbished)
Installation	Electrician, 1–2 days	Plug & Play, 15 minutes
Capacity per m²	5–10 kWh, heavy	2 kWh, 10 kg light
Efficiency	85–90%	96%
Tenant-friendly	No	Yes, mobile
Degree of Self-sufficiency	40–50%	70–85%

How to install the storage system step-by-step?

Step 1: Connect the balcony power plant (solar module + inverter) to the grid via a Schuko plug.
Step 2: Run MC4 cables from the inverter to the storage input (3 m included).
Step 3: Connect the storage system to an outlet via Schuko, pair the app for monitoring.
Step 4: Configure the EMS – set charging limit to 80 percent, prioritize household.
Step 5: Test run: Check charging during the day, discharging in the evening (app shows 1.5 kWh daily saving).

Who benefits in Scenario 1: The tenant with a home office?

Problem: Daily 5 kWh grid electricity for PC and lighting, bill €90/month. Traditionally: Pay full prices in the evening. After use: Storage covers 3 kWh, monthly saving €25. Key gain: €300 annual saving, 200 kg CO2 reduction.

Who benefits in Scenario 2: Family with electric car charging?

Problem: 10 kWh daily peak for charging, cost €1.20/kWh. Traditionally: Direct grid, €400/year extra. After use: 6 kWh stored, charging at night effectively €0.30/kWh. Key gain: €250 saving, self-sufficiency to 60 percent.

Who benefits in Scenario 3: Senior household with washing machine?

Problem: Evening consumption 2 kWh, annually €200. Traditionally: No storage, 70 percent loss. After use: Full coverage, €150 saved. Key gain: Stable supply, maintenance-free for over 8 years.

Who benefits in Scenario 4: Small business with refrigerator?

Problem: Continuous load 1 kWh, operating costs €500/year. Traditionally: Grid-dependent, peak prices. After use: 80 percent self-sufficiency, €350 reduced. Key gain: Amortization in 18 months, scalability.

Which trends make storage essential now?

By 2030, 10 million balcony power plants are expected to operate, with storage for 80 percent self-sufficiency (Fraunhofer ISE forecast). Rising grid fees (up to 50 cents/kWh) necessitate storage. DRBO Greenenergy positions itself as a pioneer with refurbished models – investing now secures 20 percent higher returns.

What are common questions about refurbished storage?

How long does the battery last?
Up to 10 years at 80 percent charge cycles, with a 30-year performance guarantee.

Is a permit necessary?
No, below 800 Wp grid-compliant, tenant-friendly.

Does it fit every inverter?
Yes, compatible with 99 percent of micro-inverters, optimal with Deye.

How much can I realistically save?
€200–400/year for a 600 Wp system, depending on solar radiation.

Can I expand it?
Yes, modular up to 8.6 kWh with DRBO Greenenergy extensions.

Does the app work reliably?
Yes, real-time data on yield, consumption, and storage level.
