This solar-operated pump, panel, and battery backup kit comes with everything needed to set up a DIY outdoor fountain. It features a flow rate of 132 gallons of water per hour and a lift of up to 56" high when 1/2" tubing is connected. When the power button is on, the pump will run via solar power when the panels are in direct sunlight. When the sun goes down the battery pack will operate for up to 4 hours on a full charge. To use the battery pack on this continual use mode, simply press the [Power] button until the [on] indicator light illuminates. This will run the pump using the battery pack until it runs out of power.
