12V Filtered Small Solar Water Fountain Pump — Brushless Submersible Circulating Pump (Single 5W Solar, Optional Lithium Battery)

Compact 12V filtered solar water pump for small fountains, fish tanks and outdoor circulating/cooling applications. The unit uses a brushless, suction submersible motor that can run without direct sunlight (powered by the internal battery when needed). An available option adds sun-shield tempered glass models for longer service life, higher efficiency and improved product quality.

This configuration includes a single 5W solar lithium battery submersible pump; lithium battery capacity is optional. The product is supplied with a waterproof, dustproof battery box that has a hanging hole — for outdoor installations hang the box or install it flatwise upside down to protect the internal lithium battery.

Solar panels are designed to be waterproof but should not be used through glass; install panels in an unobstructed, elevated outdoor location. For best performance position the solar panel at a 40 degrees angle to the horizontal so that at 12 noon the panel faces the sun’s rays (refer to the recommended installation angle used for solar water heaters).
