12V Filtered Small Solar Submersible Fountain Pump — Brushless Suction Pump, 5W Solar Option & Optional Lithium Battery for Aquarium/Outdoor Cooling

Compact 12V filtered solar water fountain pump designed for aquarium circulation, outdoor cooling and small fountain use. Available with a sun‑shield tempered glass option that extends service life, boosts efficiency and helps ensure higher product quality. The unit supports a single 5W solar option; lithium battery capacity is optional. A brushless motor is used and can operate even without sunlight. The pump includes a waterproof box with a hanging hole — for outdoor installations be sure to hang it up or place it flat, upside down; the enclosure is waterproof and dustproof to protect the internal lithium battery. Solar panels are built to be waterproof but must not be placed behind glass; mount them outdoors in an unobstructed, elevated location. Position the solar panel at about 40 degrees to the horizontal so that at 12 noon it faces the sun’s rays — follow the recommended installation angle used for solar water heaters.
