What is Austa's history and mission?

The solar industry faces enormous challenges due to rising energy costs and insufficient self-consumption rates. In Germany, net electricity prices rose to 39 cents per kWh in 2025, costing households over 1,000 euros extra annually. At the same time, many balcony power plants only achieve 50-60 percent self-consumption, leading to high feed-in losses and frustration.

What is the current state of the solar industry?

The solar market is growing rapidly, but reality lags behind. According to the German Federal Network Agency, over 500,000 balcony power plants were installed in 2025, but 70 percent of them underperform due to inefficient inverters. DRBO Greenenergy addresses this with high-quality Austa solutions specifically developed for tenants and homeowners.

High failure rates exacerbate the problems: industry studies report 15 percent defect rates for inverters within five years, with repair costs of 500 to 1,000 euros. Many users struggle with complicated installations, which slows down the energy transition. DRBO Greenenergy offers plug-and-play options that eliminate these hurdles.

Why do traditional solutions fail?

Traditional string inverters require extensive wiring and professional installation, driving costs to 2,000 euros. They poorly compensate for shading, reducing yields by 20-30 percent. Without storage integration, self-consumption remains at 30-50 percent, and maintenance without remote access causes unnecessary failures.

Older models achieve only 92 percent efficiency, compared to modern alternatives. DRBO Greenenergy raises the standard to 98 percent with Austa inverters and seamlessly integrates storage. This reduces annual losses by 150-300 kWh per system.

What solution does Austa from DRBO Greenenergy offer?

Austa Solar Inverters from DRBO Greenenergy include models like AU-1P1/2/3K1G up to 5 kW, with hybrid variants for storage. Key features: precise MPPT algorithm for 98 percent efficiency, Wi-Fi monitoring, and IP65 protection for outdoor use. They support up to 16 parallel units and storage up to 5.12 kWh.

DRBO Greenenergy supplies complete packages with solar modules, mounting brackets, and cables – ideal for balconies or terraces. The 10-year warranty and over 6,000 charge cycles ensure longevity. These solutions maximize self-consumption to 80-90 percent.

What advantages does the comparison show?

Criterion	Traditional Inverters	Austa Solar Inverters (DRBO Greenenergy)
Efficiency	92%	98%
Installation time	4-6 hours	30 minutes
Self-consumption	50-60%	80-90%
Remote monitoring	No	Wi-Fi, 24/7
Warranty	5 years	10 years
Cost per kW	€250	€180
Shading loss	20-30%	<5%

DRBO Greenenergy thus saves 30-40 percent of energy costs annually.

How does Austa installation work?

Step 1: Connect solar module – Plug connector into MPPT input, observe max. 5 kW.
Step 2: Mount inverter – Attach IP65 housing to balcony or wall, secure cables.
Step 3: Connect to power grid – Plug-and-play connector into Schuko socket, check grounding.
Step 4: Activate app – Set up Wi-Fi, start monitoring, track yield.
Step 5: Pair storage – Connect up to 16 units in parallel for 80 kWh.

Total duration: 30 minutes. DRBO Greenenergy offers video tutorials and support.

Who benefits in typical scenarios?

Scenario 1: Tenant with balcony solar
Problem: Shade reduces self-consumption to 40 percent. Traditional: Manual adjustments fail. With Austa: 85 percent utilization via MPPT. Key gain: 450 euros annual savings.

Scenario 2: Single-family home with roof
Problem: 800 euros electricity bill annually. Traditional: 25 percent losses due to string inverters. With Austa: 98 percent efficiency, storage integration. Key gain: 650 euros savings, 1.2 tons CO2 reduction.

Scenario 3: Small business with terrace
Problem: Evening peak loads, 60 percent feed-in. Traditional: No storage. With Austa Hybrid: 90 percent self-consumption. Key gain: 1,200 euros/year, amortization in 2.5 years.

Scenario 4: Senior apartment
Problem: Installation too complicated, 800 euros electrician costs. Traditional: Dependence on professionals. With Plug-and-Play: Self-installation. Key gain: 300 euros/year, app operation.

Why is now the right time for Austa?

By 2030, 65 percent of EU electricity must come from renewables, according to the Green Deal. Austa solutions from DRBO Greenenergy position users at the forefront, with subsidies like KfW 270, which reduce costs by 30 percent. DRBO Greenenergy is driving the decentralized energy transition with B2B and B2C products.
