Zero Export for Balcony Power Plants: What is it, how does it work?
Zero export initially sounds contradictory – after all, you want to feed electricity into the grid. But with balcony power plants, the goal is to use as much as possible yourself and feed as little as possible unused into the public grid.
Why Zero Export is Important
Without zero export, your balcony power plant always feeds in at full power (e.g., 800 watts). However, if you are only consuming 200 watts at that moment, 600 watts go into the grid uncompensated. With zero export, the feed-in is reduced to your current consumption.
What do I need for Zero Export?
You need a smart meter (measures your real-time consumption) and a compatible inverter or balcony battery that responds to the smart meter signals.
Smart Meter Options Compared
Shelly Pro 3EM: The most popular third-party smart meter. Measures all three phases, communicates via Wi-Fi, integrated into Home Assistant. Price: approx. €60–80.
Anker Smart Meter: The official smart meter for the Anker Solarbank series. Easy setup, best compatibility with Anker products. Price: approx. €40–80.
APsystems APmeter: Specifically for APsystems devices (EZHI, ECU-C). Three-phase, easy integration into the EMA app.
Setting up Zero Export with Anker Smart Meter
- Install the smart meter in the meter cabinet
- Integrate the smart meter into the Anker App
- Activate zero export in the app
- Done – the Solarbank regulates automatically
Conclusion
Zero export is one of the most effective methods to maximize self-consumption. With a smart meter and a compatible balcony battery, you get the most out of your solar system.
