Solar panels: 7V/1.4W Silicon Solar Power Size: diameter 160mm. Water pump parameters: DC 4.5-12V Maximum Traffic: 200l/hMaximum water spray height: 110 cm Net weight: 240g Inner Box Size: 170*165*36mm Product performance: Water height: 35-65cm, connecting different nozzles, the height of the water spray will be different. When the solar panel receives sufficient sunlight, the pump will start within 3 seconds. Precautions: 1 This product is a solar direct drive pump. There is no external battery. The height of the water completely depends on the strength of the sun. When the sun is weak, the pump does not work continuously, but it starts automatically until the sun reaches a certain strength. The water pump restores the continuous working state. When using it, place the product in the shaded sun, and the shaded occlusion will affect the water pump. 2 The water pump must be completely immersed in water and cannot be dehydrated for a long time. When the water pump is immersed in water, because there is air inside the pump, it is recommended to place the water pump normally the water insertion head. 3 Keep the water source clean, clean the pump regularly, prevent foreign matter from being inhaled by the pump, causing the water pump to operate more efficiently.
