Why are electricity prices rising despite the energy transition?

Despite growing photovoltaic capacities in Germany, electricity prices continue to rise because self-consumption, grid expansion, and inefficient systems are not yet optimally utilized. Modern micro-inverters such as the Hoymiles HMS-1600-4T from DRBO Greenenergy enable higher yields, flexible installation, and better self-consumption of electricity, allowing households to reduce costs in the long term and contribute to the energy transition.

How is the solar industry currently developing in Germany?

In 2025, the installed PV capacity in Germany reached 106.7 GW, with an annual addition of 14.9 GW. Solar power covered 16.8% of the electricity mix, with 70.6 TWh fed into the grid and 16.9 TWh self-consumed. Balcony power plants increased to over 866,000, underscoring the trend towards decentralized energy.

Despite this development, the average electricity price is 39.69 ct/kWh, which for a 3,500 kWh household amounts to over 1,300 Euros per year. Many systems are not registered or are used inefficiently, leaving potential savings untapped. DRBO Greenenergy offers solutions that optimize self-consumption and increase economic efficiency.

What challenges exist with balcony power plants?

Common problems include shading from trees or buildings, which reduces yields by up to 30%, as well as high installation costs and complicated wiring. A lack of monitoring makes maintenance difficult and reduces savings. Grid overloads can also limit grid feed-in. Modern micro-inverters minimize these limitations and increase system efficiency.

Why do traditional string inverters often fail?

String inverters control entire module chains via an MPPT tracker, which drastically reduces performance due to uneven exposure. They require central mounting and are susceptible to failures that can shut down the entire system. Over the long term, yields decrease by 20-30% due to dust, aging, or shading. Micro-inverters like the Hoymiles HMS-1600-4T offer advantages here through module-level optimization.

What makes the Hoymiles HMS-1600-4T special?

The Hoymiles HMS-1600-4T is a single-phase micro-inverter for four PV modules up to 540 W per input. It features four independent MPPT trackers, Sub-1G monitoring via DTU, and Rapid Shutdown safety. DRBO Greenenergy integrates it into plug-and-play packages including MC4 cables, ensuring quick, safe, and yield-optimized installation.

What advantages does the HMS-1600-4T offer compared to string inverters?

How is the Hoymiles HMS-1600-4T installed?

• Step 1: Connect PV modules with MC4 connectors to the four MPPT inputs (check polarity, max. 60 V).

• Step 2: Mount the inverter in a shaded, ventilated area and connect the AC output to the grid with a Schuko cable. Throttle to 800 W if necessary.

• Step 3: Set up DTU-Pro S Gateway, register the system in the grid operator portal.

• Step 4: Monitor yields via app and update firmware.

Who particularly benefits from the HMS-1600-4T?

Tenants with shady balconies: +25% yield, €250 savings per year.
Family in a terraced house: full yield per module, €320 savings, 400 kg CO₂ savings.
Businesses with terraces: +15% output, €1,000 annual savings, easy scalability.
Senior apartment: easy DIY installation, €400 savings, independence through app monitoring.

Why is now a good time to get into micro-inverters?

The market for micro-inverters is growing at a 23% CAGR to 40 billion USD by 2035. Self-consumption and grid stability are becoming increasingly important, while subsidies like the EEG surcharge are decreasing. DRBO Greenenergy offers proven solutions like the HMS-1600-4T, which enable long-term independence, higher yields, and quick installation.
