Smart feed-in for balcony power plants automatically controls battery charging and discharging cycles with app-based regulation. A battery such as the SunEnergyXT BK215 PLUS buffers surplus electricity, while control devices like the Shelly Pro 3EM maximize self-consumption – feeding into the grid or household load with a bidirectional meter. Goal: Reduce costs, achieve zero feed-in.

What is smart feed-in for balcony power plants?
Smart feed-in is the automated regulation of solar surplus into storage, household, or grid via app, to increase self-consumption to over 80%. It reduces electricity bills with dynamic tariffs like Tibber and avoids grid fees through zero feed-in. Relevant from 2026 due to mandatory bidirectional meters for 800 W.
Which hardware components do you need for smart feed-in?
For smart feed-in, you need LiFePO4 batteries like the SunEnergyXT BK215 PLUS (2.15 kWh, expandable up to 17.2 kWh) or the 500 series (5 kWh, 800 W or 2,400 W), compatible with micro inverters like the Deye SUN-M80G4-EU-Q0. Control devices like the Shelly Pro 3EM ensure zero feed-in, and the SunEnergyXT App provides smart regulation.
| Storage Type | Capacity | Price (from) | Cycles |
|---|---|---|---|
| SunEnergyXT BK215 PLUS | 2.15 kWh | €749 | >10,000 |
| SunEnergyXT 500 | 5 kWh | €1,299 | >10,000 |
| SunEnergyXT B500 Extension | 5 kWh | €999 | >10,000 |
| Refurbished Minjet | 2.016 kWh | not specified | not specified |
How do you set up a balcony power plant with battery for smart feed-in?
Install plug-and-play batteries like the SunEnergyXT BK215 PLUS with a Schuko plug, connect the Shelly Pro 3EM as a bidirectional meter. Set up rules for self-consumption in the SunEnergyXT App (iOS/Android), integrate Home Assistant for local API control. No electrician needed, VDE-compliant for tenants.
Why does smart feed-in optimize self-consumption so effectively?
The SunEnergyXT App predicts consumption via 4 MPPT trackers, stores surplus during the day in LiFePO4 cells (EVE Premium), and discharges into household loads in the evening. With the Shelly Pro 3EM, zero feed-in achieves >85% self-consumption, compared to 30% without storage – savings of up to €180/year with the Dynamic Starter Set.
Can a balcony power plant with battery utilize dynamic tariffs like Tibber?
Yes, the SunEnergyXT Dynamic Starter PLUS Set (€3,199) with 4 MPPT and API integrates Tibber/aWATTar, automatically charging at low prices. Expandable up to 30 kWh with B500 modules, optimized for volatile tariffs. Tenants benefit from refurbished sets with 0% financing via OpenBank.
