Product information

Description

The Technaxx 5121 solar panel is a black monocrystalline module designed for small-scale home energy generation. With a rated panel power of 410 W and an inverter feed-in capacity up to 800 W, the system supports feeding electricity into a 230 V household grid and achieves an estimated annual yield of about 850 kWh. The panel uses half-cell design (108 cells, 12x9), comes with MC4 connectors and weighs 45 kg, making it suitable for mounting on flat roofs, terraces, balconies, fences and other locations where compact solar modules are required.

Advantages

The panel and accompanying microinverter are lightweight and compact, allowing easy installation and connection. The microinverter offers MPP tracking and three bypass diodes for improved current efficiency, while real-time production data, alarms and energy acquisition are available through the S-Miles app. The system is optimized to cover household base load during daytime and supports straightforward feed-in to a 230 V grid.

Suitable for

  • Supplementing household electricity during daytime
  • Small rooftop, terrace or balcony installations
  • Mounting on fences or other compact structures
  • Off-grid auxiliary generation with grid-feed capability

How to use

Mount the panel on a suitable flat surface such as a flat roof, terrace, balcony or fence using appropriate racking or fixing hardware. Connect the module to the included microinverter and then connect the microinverter to the 230 V household grid following local electrical codes. Use the MC4 connectors for safe PV cable connections. After commissioning, monitor real-time production, alarms and energy data via the S-Miles app to verify correct operation.

Usage recommendations

Install panels with an unobstructed view of the sun and an appropriate tilt for your location. Ensure electrical connections and inverter integration are performed by a qualified installer and comply with local regulations. Regularly inspect connectors and the module surface for dirt or shading to maintain optimal output.
