Solar panel: 7V/1.5W monocrystalline silicon solar panel size: 160mm in diameter. Water pump parameters: DC 4.5-12V V. Maximum flow: 200L/h Maximum lift: 110cm Product performance: Water spraying height: 35-65 cm, different nozzles are connected, and the water spraying height be different. When the solar panel receives enough sunlight, the water pump start within 3 seconds. This product is a direct-driven solar water pump, and there is no additional storage battery. The height of spraying water depends entirely on the intensity of sunlight. When the sunlight is weak, the water pump not work continuously, but automatically start repeatedly until the sunlight reaches a certain intensity, and the water pump resume its continuous working state. The water pump must be completely immersed in the water, and it is not allowed to be dehydrated for a long time. When the water pump is just immersed in the water, because there is air in the water pump, it is recommended to insert the nozzle after the water pump sprays water normally. Please keep the water Precautions: source clean and clean the water pump regularly to prevent foreign bodies from being sucked into the water pump and the water pump from not working normally.
