How does a balcony power plant with storage and smart feeding in via a new two-way meter work?

Article published at: Feb 8, 2026

Electricity prices in Germany are rising rapidly, while balcony power plants with storage and intelligent feed-in offer new possibilities for self-consumption. DRBO Greenenergy provides practical solutions that enable up to 70 percent self-consumption and annual savings of 200 to 500 euros. The new two-way meter ensures precise measurement of consumption and feed-in, maximizes efficiency, and meets grid operator requirements.

What challenges currently exist in the solar industry?

The market for balcony power plants is booming: in 2025, over 500,000 systems were installed, a 40 percent increase compared to 2024. Nevertheless, 25 percent of applications fail with grid operators due to imprecise electricity measurement. Households potentially lose 15 percent of their savings due to a lack of transparency regarding feed-in and consumption.

High electricity prices of an average of 0.40 euros per kilowatt-hour further burden consumers. Without storage and intelligent management, many systems feed surplus electricity into the grid without compensation. DRBO Greenenergy addresses this with compatible systems that increase self-consumption.

Why is there a lack of precision in electricity measurements?

Traditional meters only record grid consumption one-way and ignore reverse flows. This leads to measurement errors of 10 to 15 percent, causing disputes with grid operators. According to Federal Network Agency data, 20 percent of users need to make retrofits, causing waiting times of up to eight weeks.

What are the biggest pain points for balcony power plant users?

Tenants and homeowners struggle with bureaucratic hurdles and a lack of real-time monitoring. Without storage, up to 60 percent of solar power goes unused into the grid. Dependence on volatile electricity tariffs increases the pressure to find uncomplicated solutions.

What are the disadvantages of traditional solutions?

Analog meters require separate devices for consumption and feed-in, which causes space and cost. Installations take weeks and cost 150 to 400 euros. They do not offer real-time data, which limits self-consumption to 40 to 60 percent.

Compared to modern systems, there is a lack of integration with storage and apps. Traditional setups ignore dynamic consumption fluctuations, leading to overloads or shutdowns. DRBO Greenenergy systems surpass this with bidirectional measurement.

Why are conventional meters not future-proof?

Without remote reading, meter readings must be reported manually, which creates sources of error. They do not meet VDE standards for systems up to 800 watts. DRBO Greenenergy offers certified alternatives with app integration.

What does DRBO Greenenergy's solution offer?

The balcony power plant with storage and new two-way meter from DRBO Greenenergy measures consumption and feed-in with 1 percent accuracy. Intelligent feed-in dynamically adjusts the power to household consumption, supported by energy management systems and Deye inverters. Plug-and-play compatibility with solar modules up to 800 watts enables self-consumption rates of 70 to 90 percent.

DRBO Greenenergy integrates storage in capacities from 2 to 10 kilowatt-hours, including app monitoring. The system prioritizes self-consumption and minimizes grid feed-in.

What core functions make the system superior?

Real-time monitoring, overload protection, and remote access optimize usage. DRBO Greenenergy provides complete packages with cables and mounting brackets for safe installation.
