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 the total electricity consumption. The system includes two solar modules, a suitable micro inverter and an AC connection cable that connects the inverter to a socket. The modules are designed so that they can be installed directly next to each other.

PV yield forecast for your location

The complete system contains:

  • 2x Trina Solar Vertex S TSM-DE09.08 425W solar panel monocrystalline (Black Frame)
  • 1x Hoymiles HM-600 microinverter
  • 1x 5m connection cable Betteri BC01 socket to Schuko socket

Trina Solar Vertex S 425W solar panel

The Trina Solar Vertex S is a 425W solar panel with monocrystalline cells and high-density cell connection technology. Compared to the first generation Trina Vertex S 400W, the upgraded 425W solar panel can generate more energy at a lower cost, demonstrating the exceptional value of the system. Its multi-busbar technology provides more absorption, low series resistance, improved current dissipation and increased reliability.

The Trina Solar Vertex S is certified for use with wind and snow loads of 4000 - 6000 Pa (test loads). The highly transparent and heat-tempered glass is 3.2mm thick and has an anti-reflective coating. The frame features 30mm anodized aluminum alloy.


  • Multi-busbar technology
  • High efficiency of 21.3%
  • Manufacturer product guarantee: 15 years
  • Improved power generation
  • Including connection cable
  • Excellent low light performance (IAM)
  • Easy handling
  • Flexible installation solutions for system use

Multi-busbar technology

Busbars are located on each PV module. These are busbars that are permanently printed on each solar cell. They absorb the generated direct current and lead it to the busbars. By using more busbars, Trina Solar reduces shading, shortens transport routes and lowers resistance in the modules.

Hoymiles HM-600 module inverter

The Hoymiles HM-600 is the perfect microinverter for your balcony power plant and is suitable for solar power production with a solar panel up to a peak power of 500 watts. Just like all other Hoymiles microinverters, it is suitable for long hours of operation and wide PV module application because its startup is very low (only 22V) and the DC input range of operating voltage (16-60V) is extremely wide. The Hoymiles micro-inverter converts the solar power generated by your photovoltaic system in an AC grid-compliant manner and feeds it directly into the supply grid. The unique configuration means that each PV module is controlled by an individual Maximum Peak Power Point Tracker (MPPT). This ensures that the maximum available power from each individual module is fed into the grid, regardless of the power of the other PV modules in the system. So if individual PV modules in the array are affected by shading, pollution, alignment, or mismatch, the HM-600 still ensures peak performance for its associated PV module. The result is the maximum possible energy production of your PV system.

  • Recommended module power: up to 380W
  • Max input voltage: 60V
  • Max input current: 2*11.5A
  • Rated output power: 600VA
  • Operating voltage range: 16~60V
  • Dimensions (WxHxD): 250 x 170 x 28mm
  • Weight. 3kg

socket connection

The balcony power station includes a 5m AC extension cable with a Betteri BC01 plug, matching the HM-600 inverter, on one end and an angled Schuko plug on the other end of the cable. This enables quick and uncomplicated connection to the Schuko sockets (plug type F) that are common in Germany.
