A balcony power plant with a storage system, zero-feed-in, and a smart meter stores surplus solar power and feeds nothing into the grid – ideal for tenants and homeowners. The smart meter measures real-time consumption, and the storage system, such as SunEnergyXT-compatible units, dynamically adjusts the feed-in. Advantages: Higher self-consumption, cost savings with dynamic tariffs like Tibber, and legal compliance without grid operator approval. DRBO Greenenergy offers plug-and-play sets with refurbished options.

What is Zero-Feed-in for Balcony Power Plants and why is it worthwhile?
Zero-feed-in means that no solar power is fed into the grid, but rather entirely used in the household or stored. It avoids permits and grid fees, increases self-consumption to up to 90%, and saves €200–400 annually for 800 Wp systems. Perfect for tenants, compatible with dynamic tariffs like Tibber or aWATTar.
What role does the smart meter play in the system?
Smart meters like Shelly Pro 3EM precisely measure real-time generation, consumption, and storage charging. They enable automated zero-feed-in through communication with inverters and storage units such as SunEnergyXT BK215 PLUS. Standard since 2025, with app monitoring for optimal control.
How do I connect a balcony power plant storage system to a smart meter?
1. Install Shelly Pro 3EM (DIY-friendly). 2. Pair via the SunEnergyXT app. 3. Configure storage units like SunEnergyXT 500 or BK215 PLUS for zero-feed-in. DRBO Greenenergy sets with SunEnergyXT products are plug-and-play, including accessories for balcony mounting and compatible Deye inverters.
