Perfect combination of solar panel, battery storage with adjustable output voltage, submersible pump, and LED ring for effect lighting. A beautifully illuminated fountain for the garden pond or decorative light design for a water feature. The solar panel generates enough energy in sunny summer weather to operate the pump with light while simultaneously charging the battery. This way, you can enjoy a charmingly illuminated water feature in the garden pond even in the evening. Additionally, there is the option to activate the pump with light via a switch on the battery box in the evening, allowing you to enjoy this light spectacle for several hours in the dark. An integrated regulator in the battery box allows the voltage and thus the pump's performance to be adjusted between 12 and 24 V. Plug-and-play system with a brushless pump featuring dry run and overload protection, as well as LED lighting. Various fountains can be created using the included 4 riser pipes and 2 different sprinklers (3-tier fountain and water bell).
