Offgridtec's balcony power plants offer a practical solution for generating part of the electricity required for the household yourself, thereby significantly reducing the costs for total electricity consumption. The system comprises four solar modules, a suitable micro inverter including a DTU control unit, and an AC connection cable that connects the inverter to a power outlet. The modules are designed so that they can be installed directly next to each other.
How does a balcony power plant work?
The Offgridtec balcony power plant is a space-saving solar system consisting of a solar module and a suitable Hoymiles micro inverter to feed the generated electricity into the in-house power grid. Ideally, the inverter is attached directly to the substructure of the solar module and connected to the module with the solar connector. The AC cable is connected via the inverter's battery connection and routed directly to the appropriate socket. You can choose between a conventional Schuko socket and a Wieland feed-in socket, which is included in the scope of delivery. No special settings are required to use the solar power generated in the home's power grid. If power is available from other sources in the home, this is used preferentially and supplemented by grid power if necessary.
The complete balcony power plant system includes:
- 4x Trina Solar 450W Vertex S+ dual-glass N-type TopCon solar module
- 1x Hoymiles HMS-1600-4T microinverter module inverter
- 1x Hoymiles DTU-Lite-S WiFi data transmission unit for HMT / HMS
- In order to be able to change settings in addition to monitoring, a DTU Pro-S is required instead of the DTU-Lite-S (not included in the scope of delivery).
- 1x Hoymiles HMS connection cable 3x1.5mm² Plug&Play 10m
- 4x 3m 6mm² MC-4 connection cable plug/socket extension
Trina Solar 450W Vertex S+ Dual Glass N-Type TopCon
The Trina Solar Vertex S+ (MPN: TSM-450 NEG9R.28) is an effective solar module with an output of 450W that uses monocrystalline TOPCon cells and dual-glass technology. Thanks to multi-busbar technology, it offers improved absorption, low series resistance, improved current dissipation, and reliability. It is certified for extreme wind and snow loads of 5400 - 4000 Pa and features highly transparent, 1.6 mm thick glass with anti-reflective coating. The frame is made of a 30 mm wide, anodized aluminum alloy.

Hoymiles HMS-1600-4T module inverter
The HMS-1600-4T (MPN: HMS-1600-4T) from Hoymiles is the perfect micro inverter for your balcony power plant. This compact, lightweight device (weighing only 5.56 kg) is suitable for solar power production with up to four solar panels, each with an output of 320 W to 540 W+. Just like all other micro inverters from Hoymiles, it is suitable for long operating hours and a wide range of PV module applications, as its start voltage is very low (only 22V) and the DC input range of the operating voltage (16-60V) is extremely wide.

Balcony power plants in Germany
There is currently no law or regulation in Germany governing the generation of solar power for purely personal use. The maximum limit of 600W AC PV power is a reserve value which, according to the current VDE standard, can be fed into an existing socket circuit in a house without overloading it. There are no specifications for independent circuits without additional load. All electrical installations should be carried out in accordance with VDE standards. However, the operation of a balcony power plant via a standard Schuko socket is not prohibited. Registration with the Federal Network Agency is mandatory. However, there are no known cases of fines for failure to register balcony power plants, nor are there any insurmountable problems with grid operators. Compliance with and implementation of standards and obligations is the responsibility of the plant operator. A wealth of technical and legal information on this subject can be found on relevant websites.

Auf welchem Weg lässt sich der Wechselrichter auf die maximal zugelassene 600W drosseln?
Jedoch ist bei der Anmeldung bei Netzbetreiber nicht entscheidend was Sie einstellen können, sondern was die Nennangabe des Inverter besagt.
Anmelden können Sie grundsätzlich jede Anlagen-Größe bzw. Inverter. (Privat bis 20kW)
Momentan liegt die Grenze, bis zu der man ein Balkonkraftwerk vereinfacht anmelden und selbst anschließen kann, bei einer Einspeiseleistung von 600 Watt. Dieser Wert bezieht sich auf die Ausgangsleistung des Wechselrichters der Mini-PV-Anlage. In Europa gilt seit 2016 eine Richtlinie namens "Regulation for Generators" (RFG), in der für elektrische Erzeugungsanlagen eine Bagatellgrenze von 800 Watt festgelegt ist. Das bedeutet, dass bis zu dieser Grenze die private Stromerzeugung als “nicht relevant” angesehen wird. Um den Zugang zu erneuerbaren Energien zu erleichtern, schlägt der VDE vor, diese Richtlinie zu übernehmen und die Bagatellgrenze bis 800 Watt Einspeiseleistung auch in Deutschland einzuführen.
600W bzw. demnächst 800W ist nur eine Bagatellgrenze für „Balkonkraftanlagen“, die über eine bestehende Schuko Steckdose angeschlossen werden.
Über 600W bzw. 800W muss eine Balkonkraftanlage an einem separaten Stromkreis mit entsprechender Einspeisesteckdose bzw. direktem Anschluss zum Hausanschluss mit Sicherung, installiert werden und dies nur von einer Elektrofachkraft. Viele Netzbetreiber akzeptieren bereits jetzt schon die vereinfachte Anmeldung bis 800W, ohne hinzuziehen einer EF.
