Setting up a balcony power plant with Zero Export, a new two-way meter, and storage: 1. Register the two-way meter with the grid operator. 2. Install Shelly Pro 3EM for zero-feed-in and pair it with the SunEnergyXT app (e.g., BK215 PLUS + EV3600) via Wi-Fi. 3. The storage communicates dynamically – no surplus to the grid. 4. Activate the app (Home Assistant/Tibber). Plug-and-play from DRBO Greenenergy, no electrician needed!

What exactly is Zero Export for balcony power plants?
Zero Export is a function that reduces the feed-in of electricity from a balcony power plant into the grid to zero. The microinverter (e.g., SunEnergyXT 500-series or EV3600) dynamically adjusts its output via CT sensors of the Shelly Pro 3EM and app communication. Advantages for renters: No feed-in over 800 W, compatible with new two-way meters, and ideal for dynamic tariffs like Tibber or aWATTar. DRBO Greenenergy offers SunEnergyXT BK215 PLUS with Zero-Export compatibility, also refurbished.
The Zero Export function ensures that surplus solar power flows directly into the storage unit (e.g., SunEnergyXT BK215 PLUS with 2.15 kWh) instead of going into the grid. This avoids curtailment and maximizes self-consumption. At DRBO Greenenergy, systems like the BK215 PLUS with EV3600 are bidirectionally compatible, allowing both charging and feeding. The SunEnergyXT app (iOS & Android) and Home Assistant integration enable real-time monitoring. For renters without a roof, complete packages like the Renters Starter Set for €1,548.00 are suitable.
Which new two-way meter do you need for balcony power plants?
For balcony power plants, a modern two-way meter that separately measures generation and consumption is suitable – mandatory since 2024 for systems over 600 W. It is compatible with Shelly Pro 3EM for real-time data transfer to the storage and Zero Export. Installation by the grid operator, free of charge.
| Model | Cost | Installation | Zero-Export suitability |
|---|---|---|---|
| Standard two-way meter | free (grid operator) | by grid operator | good with Shelly Pro 3EM |
| Smart meter | free | grid operator | excellent, real-time data |
| Miditronic MID | approx. €100–200 | electrician | high, CT-compatible |
| Isabellenhütte | €150–250 | grid operator | very good for balcony PV |
| Shelly-compatible | €0 (integration) | DIY | optimal for SunEnergyXT |
The two-way meter precisely measures grid consumption and generation. With the Shelly Pro 3EM from DRBO Greenenergy, it is seamlessly integrated into Zero Export systems. This ensures zero feed-in and legally compliant use. DRBO Greenenergy recommends a free consultation to check compatibility.
How does the storage communicate with the balcony power plant inverter?
The storage communicates via Wi-Fi/Modbus with the inverter (e.g., SunEnergyXT EV3600 + BK215 PLUS). Shelly Pro 3EM reads meter data, dynamically adjusts power. Steps: app pairing, mount CT clamp, activate Zero Export mode – IP65 winter-proof.

In the SunEnergyXT system (available at DRBO Greenenergy), communication takes place locally via API with a 1-second reaction time. The SunEnergyXT app pairs BK215 PLUS (2.15 kWh) and EV3600 bidirectionally. Home Assistant integration extends control. With the SunEnergyXT 500 series with 4 MPPT trackers and 5.024 Wh LiFePO4 battery (EVE cells), the main storage unit adjusts the output power (800 W or 2,400 W) to household consumption. DRBO Greenenergy offers configurable packages with 0% VAT for private individuals and a German support team (Trustpilot 4.6/5).
