The combination of a balcony power plant, storage, and intelligent communication with a bi-directional meter is increasingly becoming the standard for modern self-sufficient power supply. More and more households in Germany, Austria, and Switzerland are using mini solar systems to meet their own electricity needs and gain more independence from energy providers.
A crucial advantage of these systems is the ability to temporarily store surplus energy with a suitable energy storage unit, instead of feeding it unused into the grid. By using a bi-directional meter and smart communication interfaces, self-consumption is optimally controlled and documented.
Market trends and current data
According to current industry analyses by Statista and the German Solar Energy Society (DGS), the number of balcony power plants installed in Germany will already exceed one million in 2025. The overall market is growing by double digits annually, especially in the plug-and-play systems segment. The trend is clearly shifting from pure PV modules to complete systems with integrated storage and connection to smart home systems.
Systems with up to 2000 watts of power and battery storage between 1 and 3 kWh are particularly in demand to cover a household's typical evening needs. Integration into energy management systems such as Home Assistant or Shelly Cloud also plays a growing role.
According to forecasts by Fraunhofer ISE, from 2026 onwards, the majority of balcony power plants will be combined with intelligent metering systems. These systems will communicate bi-directionally with the grid and enable load management at the device level.
At DRBO Greenenergy we pursue the clear goal of driving the decentralized energy transition together with our customers. Our product range includes balcony power plants, solar modules, storage solutions, and microinverters. Our balcony power storage units, equipped with powerful Deye inverters and plug-and-play components, are particularly popular. We supply DIY stores, specialist retailers, and private customers – for maximum energy efficiency and easy handling.

Technological Background
Communication between the balcony power plant, storage, and bi-directional meter occurs via various protocols. Modern systems support MQTT, Modbus RTU, or WiFi-based transmissions. This allows data such as feed-in power, storage status, and grid feedback dynamics to be visualized in real time.
Bi-directional meters are the heart of the system. They measure both electricity drawn from the grid and solar power fed in. Well-known models such as the EMH eHZ-H00 or the eBZ DD3 are often used in combination with storage solutions and cloud-compatible apps.
An example: The EcoFlow PowerStream works with an intelligent power meter that transmits both charge level data and consumption statistics to the app. This ensures the household is optimally supplied with solar power without risking grid feedback.
Application Examples and ROI
Household A uses an 800W system with a 1.6 kWh Anker Solarbank. In combination with a bi-directional meter, the annual electricity consumption from the grid decreased by approximately 35%.
Household B has installed a Deye system with communication-enabled storage in a city apartment. Thanks to automatic load control via the Deye app, 300-400 kWh of self-consumption are achieved annually.
The return on investment, depending on electricity price and consumption, is usually between 5 and 7 years. Systems with communication interfaces amortize faster because they optimize energy flows more precisely.
Buying Guide
Anyone looking to invest in a balcony power plant with storage and a communication interface should ensure device compatibility. Key factors are: inverter type, battery technology, communication protocol, number of PV modules, and throttling to 600 or 800 watts.
Recommended manufacturers with stable software and support structures include Anker, Deye, EcoFlow, and Zendure. Before purchasing, it should be checked whether the meter used can measure bi-directionally. If not, an official bi-directional meter can be requested from the grid operator.
Future Developments
From 2027 onwards, plug-and-play solar systems are expected to automatically communicate with grid operators via smart meter gateways. This will not only measure energy flow but also make it actively controllable. This integration is an important step towards an intelligent energy transition at the household level.
Furthermore, balcony power plants will be more strongly integrated into local energy communities in the future. Electricity exchange, peer-to-peer trading, and dynamic tariffs will become realistic future scenarios.
Frequently Asked Questions
Can a balcony power plant with storage be operated without a bi-directional meter?
Yes, technically possible, but for precise energy management and legally compliant feed-in, a bi-directional meter is recommended.
How do balcony power plants and storage communicate with each other?
Via standard protocols such as WiFi, Modbus, or MQTT. This is how inverters, storage, and smart meters exchange data.
What are the advantages of a communication-enabled system?
Optimization of self-consumption, real-time monitoring, longer battery life, and controllable consumer profiles.
