Balcony power plant with storage unit communicates with new electricity meter: two-way meter controls feed-in

Article published at: Mar 13, 2026

Balcony power plants with storage are gaining popularity as they maximize self-consumption and reduce electricity costs. Modern systems communicate intelligently with the new bidirectional meter to precisely control grid feed-in. This creates an efficient energy management system for balconies, terraces, or gardens.

Market Trends for Balcony Power Plants with Storage

The market for balcony power plants with integrated storage is growing by over 40 percent annually in Germany. According to industry analyses, over two million systems were already registered in 2025, many of them with smart meter communication. User profiles show that tenants and homeowners primarily prefer plug-and-play solutions with a zero-export function.

At DRBO Greenenergy, we pursue a clear goal: to drive the decentralized energy transition forward together with our customers. We supply numerous hardware stores, specialist dealers, and installation companies with high-quality solar and energy storage solutions and support private customers in their implementation.

Bidirectional inverters enable precise control of grid feed-in and storage charging. The trend is towards systems with app monitoring and real-time data from the bidirectional meter. Energy communities are increasing, where several households share electricity.

How a Balcony Power Plant with Storage and Meter Works

A balcony power plant with storage generates solar power during the day, which is either consumed directly or stored in the battery. The micro-inverter converts DC to AC and communicates with the bidirectional meter. This measures consumption and potential feed-in separately.

Communication takes place via protocols such as Modbus, WiFi, or LAN. The Energy Management System (EMS) receives real-time data from the smart meter gateway and dynamically adjusts power. With zero export, no electricity flows into the grid – excess goes into storage.

Zero export prevents unwanted grid feed-in through power regulation. If the system produces more than is consumed, the inverter automatically throttles down. Smart meters with backstop are standard and comply with VDE norms.
