Solar panels: 7V / 1.4W silicon solar silicon size: 160 mm diameter. Water pump parameters: DC 4.5-12V Maximum flow: 200L/h Maximum range: 110cm Net weight: 240g Inner carton size: 170*165*36mm Product features: Water height of the water: 35-65cm, connection of different nozzles, the height of the water jet is different. When the solar panel receives sufficient sunlight, the pump starts within 3 seconds. Precautions: 1 This product is a directly driven solar pump. There is no external battery. The height of the water depends entirely on the power of the sun. When the sun is low in the sky, the pump does not run continuously, but starts automatically until the sun reaches a certain power. The water pump restores the state of continuous operation. When using the product in shaded sun, the adjustment and shaded occlusion will affect the water pump. 2 The water pump should be completely submerged in water and must not be dehydrated for a long time. When the water pump is submerged in water because there is air in the pump, it is recommended to place the water pump on the water inlet head normally. 3 Keep the water source clean, clean the pump regularly, prevent foreign objects from being sucked into the pump, the water pump works after
