In Germany, balcony power plants are booming as a simple way to utilize clean solar energy, but many systems give away up to 70 percent of the energy produced due to insufficient storage. According to the Federal Network Agency, over 500,000 balcony power plants were registered in 2025, accounting for approximately 10 percent of private electricity consumption. The Anker Solarbank 2 E1600 Pro solves this with 1.6 kWh capacity, expandable to 9.6 kWh, and an integrated inverter to increase self-consumption to up to 97 percent.
What challenges exist in the balcony power plant industry?
The boom in balcony power plants shows clear figures: In 2025, they reached an installed capacity of over 2.5 gigawatts, as reported by Fraunhofer ISE. Nevertheless, self-consumption in systems without storage often remains below 50 percent, as solar power is generated during the day but consumed in the evening. This leads to high grid feed-in and missed savings of up to 300 euros annually per system.
Tenants and homeowners struggle with lack of space and complicated installations. Many systems require electricians, incurring costs of 200 to 500 euros. Additionally, flexibility is lacking: different module orientations reduce yield by 20 to 30 percent without optimized trackers.
DRBO Greenenergy addresses these problems with practical solutions such as plug-and-play storage units and bidirectional inverters specifically designed for balconies.
Why do traditional solutions fail for balcony power plants?
Traditional storage systems without integrated inverters require separate devices, driving costs up to over 1,000 euros and doubling space requirements. Without multi-MPPT trackers, systems with varying module orientations lose up to 25 percent efficiency, compared to modern systems with four trackers.
Simple batteries without app control leave users in the dark: no real-time data means unused capacities. DRBO Greenenergy offers alternatives here with high-quality Deye inverters and energy management systems that measurably increase self-consumption.
In addition, older models lack modularity: expansions are expensive and complicated, while new systems scale seamlessly.
What makes the Anker Solarbank 2 E1600 Pro the ideal solution?
The Anker Solarbank 2 E1600 Pro combines a 1.6 kWh LiFePO4 storage unit with an 800 W inverter and four MPPT trackers for up to 2,400 watts of PV input. It stores surplus electricity and feeds it back into the grid when needed, with 6,000 charge cycles for a 15-year lifespan.
App control enables real-time monitoring and dynamic feeding, compatible with up to four 500 W modules. The plug-and-play installation takes less than 30 minutes, without an electrician. DRBO Greenenergy complements this with complete packages including mounting accessories for balconies.
The blackout function delivers up to 1,000 watts directly via a power outlet, even off-grid.

| Self-consumption | 40-50% | Up to 97% with app control |
| Lifespan | 3,000 cycles | 6,000 cycles, 10 years warranty |
| Additional costs | +500 Euros for inverter | All-in-one, no extras |
DRBO Greenenergy offers refurbished versions at fair prices, including accessories.
How to install the Anker Solarbank 2 E1600 Pro step-by-step?
-
Step 1: Connect PV modules with MC4 cables to the four inputs, max. 600 W per tracker.
-
Step 2: Plug the AC connector into a household socket and download the app (Anker SOLIX) to connect to Wi-Fi.
-
Step 3: Install Smart Meter optionally for precise feed-in control – reaction time under 3 seconds.
-
Step 4: Dock expansion batteries if necessary, check capacity.
-
Step 5: Register the system with the grid operator (simplified by app data).
DRBO Greenenergy provides instructions and support for a smooth start.
Who benefits from the solution in which scenarios?
Scenario 1: Tenant with a south-facing balcony
Problem: 1.5 kW surplus during the day, 80 percent grid consumption in the evening. Traditionally: 50 euros monthly costs.
After deployment: Stores 1.2 kWh daily, covers evening consumption. Effect: 35 euros savings per month. Key gain: 420 euros/year, no feed-in losses.
Scenario 2: Family with north/south modules
Problem: Uneven orientation halves the yield. Traditionally: Only 800 W usable.
After deployment: 4 trackers compensate, full 2,400 W. Effect: 2,200 kWh/year instead of 1,200. Key gain: 250 euros savings, scalable.
Scenario 3: Terraced house needing blackout protection
Problem: Power outages cost 100 euros per day. Traditionally: No reserve.
After deployment: 1,000 W emergency power directly available. Effect: Devices powered for 8 hours. Key gain: Security, 150 euros avoidance costs.
Scenario 4: Expansion for large consumers
Problem: 3 kWh daily demand, storage too small. Traditionally: New purchase necessary.
After deployment: Expanded to 9.6 kWh. Effect: 95 percent self-sufficiency. Key gain: 600 euros/year, DRBO Greenenergy packages starting from 800 euros.
Why is entering storage solutions now crucial?
The EEG amendment 2026 limits feed-in to 2 kW, making storage mandatory for full utilization. BDEW forecasts electricity prices to reach 40 cents/kWh by 2027. DRBO Greenenergy is driving the energy transition forward with solutions for tenants to factories – act now for amortization in 2-3 years.
