What is a balcony power plant with 8 modules and storage?
A balcony power plant with 8 modules and storage is an extended plug-and-play solar solution with 8 solar modules, micro inverters like the Deye SUN-M80G4-EU-Q0, and storage units like the SunEnergyXT BK215 PLUS. It maximizes self-consumption by storing surplus electricity and offers emergency power capability.
These systems differ from smaller installations by offering higher performance for larger households. With 8 modules, such as the OSDA 450 Wp Full Black from the DRBO Greenenergy 900 Wp Set (scalable), you can achieve peak outputs of up to 3.6 kWp. The SunEnergyXT BK215 PLUS storage unit (2.15 kWh, expandable up to 17.2 kWh) integrates seamlessly for up to 90% self-consumption.
Advantages include plug-and-play installation without an electrician, IP65 protection for outdoor use, and app monitoring via the SunEnergyXT App. DRBO Greenenergy, as an authorized SunEnergyXT dealer, offers configurable packages such as the BK215 PLUS Economy Pack with 4× 450 Wp modules, expandable to 8 modules.
What output does an 8-module system with storage provide?
An 8-module system with storage delivers a peak output of up to 3.6 kWp with 450 Wp modules, with 800 W feed-in via Deye SUN-M80G4-EU-Q0 and a storage capacity of 4–8 kWh for optimal self-consumption optimization.
With 8× OSDA 450 Wp modules (as in the DRBO 900 Wp Set), the total output is 3,600 Wp. The annual yield can be up to 3,800 kWh, depending on location and orientation. Recommended storage: SunEnergyXT BK215 PLUS (2.15 kWh per module, up to 8 modules for 17.2 kWh) or 500-series (5 kWh, expandable up to 30 kWh).
| System | Peak output | Annual yield (approx.) | Storage size | Costs (approx., DRBO) |
|---|---|---|---|---|
| 4 Modules | 1.8 kWp | 1,900 kWh | 4.3 kWh (2× BK215 PLUS) | €1,398 |
| 8 Modules | 3.6 kWp | 3,800 kWh | 8.6 kWh (4× BK215 PLUS) | €2,696 (Storage Tower Set) |
Perfect for dynamic tariff users like Tibber or aWATTar: The Dynamic Starter PLUS Set from DRBO Greenenergy automatically charges the storage at favorable prices.
What does the wiring diagram for 8 modules look like?
The wiring diagram for 8 modules includes 4× Deye SUN-M80G4-EU-Q0 micro-inverters (2 modules parallel each, 2 MPPT), connected to SunEnergyXT BK215 PLUS storage via a Schuko plug and Shelly Pro 3EM for zero feed-in.
Step-by-step: 1. Connect modules in pairs with MC4 cables (1 m included) to the MPPT inputs of the Deye inverters (Max. DC 2× 600 W, 33–55 V). 2. Connect inverter outputs (Schuko cable 5–15 m) in parallel to storage or socket. 3. Couple storage (BK215 PLUS) with EV3600 bidirectional inverter for charging/feeding in.
