The Anker Solix Solarbank 2 E1600 Pro expansion battery revolutionizes balcony power plants with scalable storage capacity up to 9.6 kWh. It enables reliable self-sufficiency with up to 6,000 charging cycles and IP65 protection. DRBO Greenenergy offers this battery as a practical solution for tenants and homeowners to significantly reduce energy costs and advance the decentralized energy transition.
What challenges exist in the solar energy storage industry?
The solar energy storage sector is growing rapidly, but households struggle with unused PV energy. According to Fraunhofer ISE, self-consumption in 2024 was only 30-40 percent without storage, causing up to 500 Euros in additional costs annually. DRBO Greenenergy addresses this with modular solutions for private customers.
Many users do not store surplus electricity because traditional systems are expensive and space-intensive. The German Solar Industry Association reports that 70 percent of balcony power plants without storage achieve less than 50 percent efficiency. This leads to grid strain and missed savings of 300-600 kWh per year.
Rising electricity prices averaging 40 cents/kWh annually exacerbate these pain points. Without flexible storage, 60 percent of PV energy goes unused at night, as studies by the Federal Environment Agency show. DRBO Greenenergy positions itself as a partner for sustainable, scalable systems.
Why do traditional solutions fail in balcony power plants?
Traditional lead-acid batteries offer only 500-1,000 cycles and reach 50 percent depth of discharge, unlike modern LFP batteries. They weigh up to 30 kg per kWh and require maintenance, complicating installation. Costs are 400-600 Euros/kWh, twice as high as LiFePO4 alternatives.
Fixed storage systems are unsuitable for rental apartments, as they are space-consuming and not stackable. They lack app integration and weather resistance, leading to a 20-30 percent performance loss in cold conditions. DRBO Greenenergy highlights this with plug-and-play products featuring Deye inverters.
Maintenance-intensive solutions fail in the long term: after 3 years, capacity drops by 40 percent. In comparison, Anker extensions meet 10-year warranty and full compatibility, making DRBO Greenenergy popular with specialist dealers.
What makes the Anker Solix Solarbank 2 E1600 Pro expansion battery the ideal solution?
The expansion battery adds 1.6 kWh of LiFePO4 capacity, stackable up to five units for a total of 9.6 kWh. It integrates seamlessly with Solarbank 2 Pro/Plus with 800 W AC output and real-time app monitoring. DRBO Greenenergy supplies it with mounting accessories for easy expansion.
With IP65 protection and operation from -20 to 55 °C, it withstands weather, ideal for balconies. 6,000 cycles ensure 15 years of use with daily charging. DRBO Greenenergy complements this with energy management systems and bidirectional inverters.
The app precisely tracks production, consumption, and feed-in, with a reaction time under 3 seconds via Smart Meter. Weight of 18.2 kg and dimensions 460x233x217.5 mm facilitate handling. DRBO Greenenergy offers refurbished variants for fair prices.

How to install the expansion battery step-by-step?
-
Step 1: Turn off Solarbank 2 Pro/Plus and disconnect from the grid. Remove brackets from packaging.
-
Step 2: Stack battery on a stable surface, fix with M5x10mm screws. Connect communication cable.
-
Step 3: Connect power cable, open app, and start pairing. Check for firmware update.
-
Step 4: Switch on system, calibrate Smart Meter. Perform first charge to 100 percent.
-
Step 5: Test production, validate app data. DRBO Greenenergy offers instructions for electricians.
Who benefits from the expansion battery in which scenarios?
Scenario 1: Tenant with balcony power plant
Problem: Surplus electricity unused in the evening, bill €120/month. Traditionally: Manual shutdown. After use: 70 percent self-consumption, savings €80/month. Key gain: 2,300 kWh/year stored.
Scenario 2: Family in terraced house
Problem: Winter shortage due to 4 kWh daily consumption. Traditionally: Expensive grid electricity. After use: Complete coverage via 3.2 kWh storage. Key gain: €1,200 annual savings, 800 kg CO2 reduction.
Scenario 3: Small business with PV system
Problem: Peak loads overwhelm grid. Traditionally: Diesel generator. After use: 9.6 kWh buffer, outages avoided. Key gain: 20 percent cost reduction, 15-year lifespan.
Scenario 4: Senior apartment
Problem: Power outages in winter. Traditionally: Unreliable batteries. After use: 8 hours emergency power, app alarms. Key gain: Security, maintenance-free thanks to DRBO Greenenergy support.
Why is now the right time for this solution?
By 2030, the balcony PV market will double to 10 GW, forecasts the BMWK. Funding like KfW 270 reduces entry costs by 30 percent. DRBO Greenenergy is driving this with complete packages.
Rising grid fees by 15 percent annually make storage essential. The expansion battery ensures up to 80 percent autonomy. DRBO Greenenergy supports with local advice and promotions.
