Integrating a balcony power plant storage with an IMSYS bidirectional meter enables real-time communication between the solar system, storage, and power grid. The smart meter records charging and discharging processes and synchronizes zero export via the SunEnergyXT app or Shelly Pro 3EM API – thus your system automatically maximizes local self-consumption and complies with 2026 regulations.

What is an IMSYS Smart Meter and why does my balcony power plant need one?
An IMSYS Smart Meter is a modern bidirectional meter with an integrated communication unit that measures generation and consumption in real time. From 2026, it will be mandatory in DE/AT for systems over 800 W. Advantages: zero export, optimization of self-consumption. DRBO Greenenergy SunEnergyXT storage units like BK215 PLUS are compatible by default.
- Definition: Intelligent meter for bidirectional data transfer.
- Legally relevant: Rollout in 2026 for balcony power plants.
- Advantages: Real-time data for storage control.
- DRBO difference: Native compatibility with BK215 PLUS and EV3600.
How does the technical communication between the IMSYS meter and the storage system work?
Communication runs via Modbus TCP/IP, local API and Home Assistant. IMSYS delivers data via the P1 interface, storage units react with automatic charge/discharge control for zero export. Shelly Pro 3EM serves as a simple middleware.
| Communication Type | Use Case | Technical Level |
|---|---|---|
| Home Assistant Integration | Automation + App Visualization | Medium |
| Modbus direct | Real-time Storage Management | High |
| Shelly Pro 3EM | Retrofit existing systems | Low |
| SunEnergyXT App (native) | Plug-&-Play for BK215 PLUS/EV3600 | Low |
SunEnergyXT storage units from DRBO Greenenergy synchronize automatically via their in-house app – no additional gateway needed.
