solar panel specifications: Rated voltage: 7V Rated power: 1.4W Material: Monocrystalline silicon, PET laminated Water pump specifications: Working voltage: DC 7V Working current: 150MA Maximum lift: 100CM Maximum flow: 180L/H Pump life:>20000 hours Water pump noise: Packing specification: Inner box size: 120*120mm Weight: 200g Specifications: The solar brushless water pump adopts Hall element with high sensitivity and low power consumption, and is driven by efficient and intelligent electronic circuit. The volute design in fluid mechanics is adopted for the impeller cavity to reduce the resistance of water flow, so that the comprehensive performance is 20% higher than that of the solar water pump with traditional structure. It also solves the shortcomings of the current brushless solar water pump, which is difficult to start, low efficiency and poor stability. The water pump can be connected to a variety of different shapes of the nozzle, spray different types of water. Product performance: Spray height: 30 -- 60cm, connect different nozzles, the height of the water spray will be different. When the solar panel receives sufficient sunlight, the water pump will start within 3 seconds. Method of use: 1) Assemble the product according to the schematic 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 sufficient light, the pump works normally. 3) When the water pump is just put into the water, there is air in it, which may affect the water spray effect. After the water pump sprays water normally, connect the nozzle Package Included: 1 set * solar fountain
