More power – fewer limitations in the field.
Thanks to its high output power, the SP420 effectively converts sunlight into a stable energy source. It is the perfect panel for powering large power stations, camping equipment, and emergency systems. High efficiency means charging is faster and more predictable, even when sunlight duration is limited.
23.4% efficiency – genuinely faster charging.
The monocrystalline silicon cells used in the SP420 achieve a conversion efficiency of 23.4%. This means better utilisation of sunlight and shorter charging times for power stations. The panel also performs well in less-than-ideal conditions, providing a stable energy yield throughout the day.

IP67 resistance – designed for outdoor use.
The SP420 panel is protected with an ETFE layer, which shields the cells from UV radiation, scratches, and moisture. The IP67 rating means it is dust and splash-proof, making the panel suitable for demanding outdoor conditions — camping, mountains, or by the water.
Adjustable tilt angle – maximum energy yield.
Built-in kickstands allow for quick positioning of the panel at the optimal angle to the sun. This makes it easy to increase charging efficiency depending on the time of day and weather conditions. This is a practical solution that has a real impact on the amount of energy harvested.


Wide compatibility thanks to MC4 connectors.
Standard MC4 connectors ensure compatibility with FOSSiBOT portable power stations, including the F3600 model, and many other solar systems. The ability to connect several panels into one kit allows you to flexibly adjust the configuration to your power needs.
Foldable and mobile – ready for the road.
The foldable design and convenient handle make the FOSSiBOT SP420 easy to transport and quick to set up. It is the perfect panel for those travelling by motorhome, working in the field, or needing a reliable source of emergency power. Unfold, set up, and use — without permanent installation.
