Balcony power plant with storage and zero export?

Article published at: Apr 7, 2026

A balcony power plant with storage and zero export enables maximum self-sufficiency by storing surplus solar power instead of feeding it into the grid. Modern systems automatically adjust power output to household consumption, significantly reducing energy costs and meeting regulatory requirements. DRBO Greenenergy offers efficient, easy-to-install complete solutions for private and commercial users.

What is a bidirectional meter?

A bidirectional meter measures both electricity drawn from the grid and electricity fed into it separately and in real time. It is a central component of modern solar systems with storage, as it provides precise data on energy flow.

These meters replace outdated models and enable precise communication with inverters and energy management systems. Especially in zero-export systems, the bidirectional meter ensures that no energy flows back into the public grid. DRBO Greenenergy relies on compatible solutions that guarantee seamless integration and high measurement accuracy.

How does Zero Export work?

Zero Export ensures that no surplus electricity is fed into the public grid. Instead, the energy is either consumed directly in the household or temporarily stored in a battery.

The system is based on real-time data from the bidirectional meter. The inverter dynamically adjusts the output and reduces electricity production as soon as self-consumption is covered. DRBO Greenenergy integrates intelligent control systems that make these adjustments in seconds, ensuring maximum efficiency.

How does the storage communicate with the meter?

Communication between the storage, inverter, and meter occurs via protocols such as Modbus RTU or RS485. These enable stable and fast real-time data transmission.

This connection allows the system to precisely control the energy flow. The storage is automatically charged when there is surplus energy and discharged when there is demand. DRBO Greenenergy uses modern interfaces to ensure seamless integration into existing energy systems.

What are the advantages of a balcony power plant with storage?

A balcony power plant with storage significantly increases self-consumption and reduces dependence on the electricity grid. Users benefit from lower electricity costs and greater energy independence.

Additionally, storing solar power allows for its use even in the evening hours. DRBO Greenenergy systems are modular, durable, and particularly easy to install. They are suitable for both tenants and homeowners and actively contribute to reducing CO₂ emissions.

Which inverter do I need for this?

For an efficient system, a compatible inverter that supports Zero Export and can communicate with the meter is required.

Suitable models have bidirectional functions and support modern communication protocols. DRBO Greenenergy recommends powerful and efficient inverter solutions that are specifically optimized for use with storage systems and enable high energy yield.

How do I install the system?

Installing a balcony power plant with storage is simple and in many cases does not require a professional installer. The components are connected to each other and plugged into the power grid via a socket.

After assembly, setup is done via an app, where the Zero Export mode is also activated. DRBO Greenenergy offers user-friendly complete systems with clear instructions and accessories, so that installation can be carried out quickly and safely.
