Offgridtec Balcony power station 1780w Blackframe Mini-PV Solaranlage inkl. hms-1600-4t und DTU-Lite-S

The balcony power plants from Offgridtec offer a practical solution to generate a portion of the electricity needed for households, significantly reducing overall electricity costs. The system includes two solar modules, a suitable micro-inverter with a DTU control unit, and an AC connection cable that connects the inverter to a power outlet. The modules are designed to 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 compatible Hoymiles micro-inverter to feed the generated electricity into the household electrical network. The inverter is ideally attached directly to the substructure of the solar module and connected to the module using a solar connector. The AC cable is connected via the battery terminal of the inverter and routed directly to the appropriate outlet. You can choose between a conventional Schuko outlet and a Wieland feed-in socket, which is included in the delivery. No special settings are required to use the generated solar power in the home's electrical network. If there is power from other sources in the house, this is preferentially used and supplemented with grid power if needed.

The balcony power plant complete system includes:

• 4x Trina Solar 445W Vertex S+ Dual-Glass N-Type TopCon Solar Module
• 1x Hoymiles HMS-1600-4T Micro-inverter
• 1x Hoymiles DTU-Lite-S WLAN Data Transmission Unit for HMT/HMS
  • To have the option to change settings in addition to monitoring, a DTU Pro-S is required instead of the DTU-Lite-S (not included)
• 1x Hoymiles HMS Connection Cable 3x1.5mm² Plug&Play 10m
• 4x Connection Cable MC4 to MC4 6mm² 2m

Trina Solar Vertex S+ 445W Solar Module

The Trina Solar Vertex S+ (MPN: TSM-NEG9R.28) is an efficient solar module with a power output of 445W, using monocrystalline TOPCon cells and dual glass technology. Thanks to the multi-busbar technology, it offers improved absorption, low series resistance, enhanced current collection, and reliability. It is certified for extreme wind and snow loads of 5400 - 4000 Pa and features high-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 Micro-Inverter

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

• MPPT voltage range: 16-60V
• Switch-on voltage: 22V
• Maximum input voltage: 65V
• Maximum input current: 4*14A
• Maximum input short-circuit current: 4*25A
• Nominal output power: 1600VA
• Nominal output current: 6.96A
• Nominal output voltage/range: 230V / 180-275V
• CEC peak efficiency: 96.70%
• Operating temperature range: -40°C - +65°C
• Dimensions (WxHxD): 331 x 218 x 40.6 mm
• Weight: 5.56kg

Balcony Power Plants in Germany

Currently, there is no law or regulation in Germany that governs the generation of solar power for pure self-consumption. The limit of a maximum of 600W AC PV output is a reserve value that can be fed into an existing socket circuit of a house without overloading it, according to the current VDE standards. For independent circuits without additional loads, nothing is specified. Every electrical installation should comply with VDE standards. However, the operation of a balcony power plant via the usual Schuko socket is fundamentally not prohibited. Registration with the Federal Network Agency is mandatory. However, there have been no known cases of fines for not registering balcony power plants, nor are there insurmountable problems with grid operators. Compliance with norms and obligations falls to the plant operator. There is already much technical and legal information available on reputable websites regarding this topic.
