How many balcony power plants are allowed per socket?
A maximum of 800 watts of feed-in is permitted per socket and circuit according to VDE-AR-N 4105 to ensure grid stability. A total of up to 2 kW is possible with registration with the grid operator; there is no fixed upper limit for separate circuits.
The 800-watt limit applies strictly per circuit, as higher outputs could overload the house installation. Many households have multiple circuits, so 2–3 balcony power plants can be operated in parallel. DRBO Greenenergy offers suitable complete sets such as the 900 Wp balcony power plant with Deye SUN-M80G4-EU-Q0 inverter for 800 W nominal output, ideal for individual sockets.
| Number of BPPs | Output | Registration required | DRBO example cost |
|---|---|---|---|
| 1 | 800 W | No (up to 800 W) | €269.00 (900 Wp Set) |
| 2 | 1,600 W | Yes, from 800 W total | €538.00 (2x 900 Wp) |
| 3 | 2,400 W | Yes, grid operator | €807.00 (3x 900 Wp) |
This table shows comparisons for single and multiple systems. All DRBO sets are Plug & Play with Schuko connection and 0% VAT for private individuals.
What applies to tenants: Maximum number of balcony power plants?
For tenants, 2–3 balcony power plants on separate sockets are legal with landlord consent. The 800 W limit per socket remains, and ownership of the system remains with the tenant.
Under tenant law, the landlord must agree, as drilling or mounting affects the apartment, but socket connections are unproblematic. DRBO Greenenergy offers the Tenant Starter Set for €1,548.00 (RRP €1,798.00) as a legally secure option without roof mounting. The German support team provides landlord letter templates and free advice.
In practice, systems such as the DRBO 900 Wp Balcony Power Plant Plug & Play with 2x 450 Wp OSDA Full Black modules and Deye inverter are suitable. Expandable with SunEnergyXT BK215 PLUS head storage (2.15 kWh, €749.00).
How do I connect 2 balcony power plants?
Connecting two balcony power plants: Place them on separate sockets, in parallel without interference. Plug & Play with Schuko cables, no electrician required for DRBO sets.
Use different circuits, e.g., kitchen and living room. DRBO Greenenergy complete sets such as the 900 Wp set include 5m/10m/15m Schuko cables. Monitor via app (SunEnergyXT App or Deye WLAN). Check overvoltage protection – all products like APsystems EZ1-M (IP67) are VDE compliant.
For higher performance: Deye SUN-M200G4-EU-Q0 (2,000 W) for extended circuits, but note registration from 800 W total.
Can I combine multiple balcony power plants with storage?
Yes, combining multiple balcony power plants with storage is possible, e.g., up to 17.2 kWh with BK215 PLUS. Higher self-consumption and dynamic tariff optimization (Tibber/aWATTar).
SunEnergyXT BK215 PLUS (2.15 kWh, expandable with B215 PLUS) fits Deye SUN-M80G4-EU-Q0 or EV3600. The Dynamic Starter PLUS Set (€3,199.00) optimizes for dynamic tariffs. Refurbished Minjet storage (2,016 Wh) as an affordable addition.
Advantages: Emergency power up to 2.4 kW, app integration (Home Assistant). SunEnergyXT 500 (5 kWh, 800 W) expandable up to 30 kWh with B500 modules.
