How:Mini Solar Fountain Swimming Pool Fountain-Waterfall Garden Decoration Outdoor Bird Bathtub Solar Floating For Water CourtyardProject Type: EternalProduct Size: 13cm/ 16cm/ 18cm Light Color With Light Battery Solar Panel: 7V/1W Monocrystalline Silicon Solar Panel Size: Diameter 130mm, 160mm, 180mm. Pump parameters: DC 4.5-12V maximum flow: 200L/h maximum head: 110cm Product net weight: 200, 250, 300gFeatures-Solar energy fountain is a landscape fountain device that uses solar energy to drive water pumps to pump water. This product uses high-efficiency solar panels and a new type of brushless water pump, which has the advantages of fast starting, high efficiency and strong stability. In addition, the product floats, no external power supply is required, easy installation and simple operation. It is widely used in garden decoration, bird bathing, aeration of water circulation in small pond, rock fountains and other places. Installation is simple and easy to use. As long as there is no direct sunlight, the pump can start working. This solar brushless water pump adopts high-sensitivity and low-power hall elements, combined with efficient and intelligent electronic drive, and adopts volute design in fluid mechanics for the impeller cavity to reduce the resistance of water flow, so that the overall performance is better than that of the traditional structure. The efficiency of the solar water pump is increased by 20%. It also solves the shortcomings of current brushless solar water pumps, which are difficult to start, have low efficiency, and poor stability. The water pump can be connected to different nozzles with different shapes to spray different types of water. Precautions:1 This product is a direct drive solar water pump without external battery. The height of the water jet depends entirely on the strength of the sun. When the sun is weak, the pump will not run continuously, but will automatically start repeatedly until the sun reaches a certain intensity, the pump will resume continuous operation. When using, please place the product in unobstructed sunlight. Shading will affect the normal operation of the pump.2 the pump must be completely submerged in water and must not be dehydrated for a long time. When the water pump is simply submerged in water, because there is air in the water pump, it is recommended to wait for the water pump to spray normally before inserting the nozzle.3 Please keep the water source clean and clean the pump regularly to prevent the pump from sucking foreign objects and cause the pump not to work normallyPlease understand that there may be 1-2cm error in manual measurement. Due to different monitor settings, color deviation may vary. Package Included:1 * Solar FountainDear buyers, welcome to our store. We guarantee the quality of our products. Welcome to visit.
