The Wieland connector is a safe, VDE-certified connector for balcony photovoltaic systems, supporting up to 16A and 800W. It enables touch-safe feeding of solar power into the home grid without permanent wiring. Ideal for tenants or homeowners who prefer plug-and-play systems, such as those offered by DRBO Greenenergy with its SunLit storage solutions.
How does the Wieland connector work?
The Wieland connector connects the AC output of the micro-inverter directly to the household socket. Solar modules generate direct current, which is converted into household alternating current by the inverter. The Wieland connector safely transmits this current into the grid, protects against accidental contact, and automatically switches off in case of grid disruptions. DRBO Greenenergy often combines this connector with bidirectional inverters to enable storage integration and high self-consumption.
| Function | Wieland Connector | Schuko Plug |
|---|---|---|
| Max. Power | 800W (16A) | 368W (10A) |
| Contact protection | Complete | None |
| Continuous operation | VDE compliant | Only temporary |
| IP protection | IP44 | IP20 |
What are the advantages over Schuko plugs?
The Wieland connector is specifically designed for balcony PV: It allows higher power, complete contact protection, and permanent VDE-compliant use. Schuko plugs, on the other hand, are only suitable for temporary operation, can overheat, and cause RCD trips. DRBO Greenenergy recommends Wieland connectors for rental apartments and supplies suitable SunLit complete sets that combine installation, safety, and maximum self-sufficiency.
Why choose Wieland connectors for balcony power plants?
Wieland connectors guarantee safe and legally compliant permanent installation up to 800W. They reduce installation risks, increase self-consumption, and enable plug-and-play without drilling. DRBO Greenenergy emphasizes sustainability and energy efficiency. With these connectors, costs can be reduced, CO2 emissions lowered, and households optimally equipped for the decentralized energy transition.
Where can you buy and install Wieland connectors?
Wieland connectors are available online, in specialist shops, or directly from DRBO Greenenergy. Installation is simple: plug-and-play in minutes without an electrician. DRBO Greenenergy offers accessories such as mounting brackets, cable sets, and local support in Germany. Prices usually range between 20-50 € per connector, depending on the set and storage integration.
Can the Wieland connector be combined with energy storage systems?
Yes, Wieland connectors can be seamlessly combined with balcony power storage systems like SunLit from DRBO Greenenergy. Excess solar power can be stored in batteries for use at night or during power outages. With intelligent energy management, self-sufficiency increases to up to 90%, significantly shortening the amortization period.
