Solar Fountain, DC Brushless Water Pump Solar Panel Specifications: Rated voltage: 7V Rated Power: 1.4W Material: Monocrystalline Silicone Epoxy Water Pump Specifications: Working voltage: DC 7V working current: 165MA Maximum head: 100CM Maximum flow: 180L/H Pump life: 20000 hours of pump noise: 45DB Package size: Outer box size: 450*350*355mm Inner box size: 170*165*43mm Weight: 250g Product performance: Spray height: 30-50cm, the height of spray water will be different when connecting different nozzles. When the solar panel receives enough sunlight, the water pump will start within 3 seconds. How to use: 1) Assemble the product according to the block diagram. 2) Place the solar panel in a suitable place to ensure that it is not blocked by other objects. When the solar panel receives enough light, the water pump works normally. 3) When the water pump is just put into the water, there is air in it, which may affect the spray effect. It is recommended to wait for the water pump to spray normally before connecting it to spray. Note: 1 This product is a direct drive solar water pump without external battery. The height of the spray water depends entirely on the strength of the sun, in the sun. When the light is weak, the pump will not work continuously, but it will automatically restart until the sunshine reaches a certain intensity, and the pump will start working continuously again. When using, please place the product away from sunlight. Shading will affect the normal operation of the pump . 2 The pump must be fully immersed in water and cannot be dehydrated for a long time. When the water pump is just immersed in water, because there is air in the water pump, it is recommended to wait until the water pump sprays normally before inserting the nozzle. 3 Please keep the water source clean and clean the water pump regularly to prevent foreign matter from being sucked into the water pump and preventing the water pump from working normally. This brushless solar water pump adopts high-sensitivity and low-power Hall elements, coupled with intelligent electronic circuit, and adopts the fluid mechanics volute design for the impeller cavity to reduce the resistance of the water flow, so the overall performance is better than the traditional Solar structured water pump efficiency is increased by 20%. It also solves the shortcomings of current brushless solar water pumps which are hard to start, low efficiency and low stability. This water pump can be connected to various nozzles of different shapes to spray different kinds of water. Quantity delivered: 1 piece
