## Long 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
