VB181A11Product Description:The solar brushless pump low-power high-sensitivity Hall elements， with intelligent and efficient electronic circuits drive， and uses fluid mechanics volute design for the impeller chamber to reduce the flow resistance， so that the overall performance than the conventional structure solar pump efficiency up to 20%. Also solves the brushless solar pump starts hard， low efficiency， poor stability shortcomings.The pump can be connected to a variety of different shapes of nozzle， spray different water types.Solar panels Specifications:Rated voltage: 7V Rated Power: 1.5W Material: monocrystalline silicon， PET laminationPump Specifications:Operating Voltage: DC 7-12V Operating Current: 150MA maximum lift: 100CMMaximum flow: 180L / H pumps life:> 20，000 hours Pump noise: <45DBPerformance:Water height: 30--60cm， connect different nozzles， spray height will be different.When the solar panel receives plenty of sunlight， the pump will start in 3 seconds.How to use:1) Press schematic assembled products.2) The solar panel is placed in the right place， to ensure that the light is not shielded by other objects. When the solar panel receives plenty of light， the pump will work properly.3) When the pump just into the water， there are air， water may affect results. After the recommendations of normal water pump， then connect the nozzle.NOTES:After a product is the solar direct drive pump， no external batteries， a high degree of water depends entirely on the strength of the sun， when the sunlight is weak， water pumps will not work continuously， but will automatically start again until the sun reaches a certain intensity Pump resume continuous operation. Please use the product when placed in an unobstructed sunlight， shadow shelter will affect normal operation of the pump. Need storage or storage with LED lights， please choose this company's other models.2 The pump must be completely immersed in water， not long dehydration work. When the pump just immersed in water， since the water pump after the air inside， recommendations normal water pump nozzle is inserted.3 Keep the water clean， regular cleaning pumps， pump suction to prevent foreign matter is caused by the pump is not working properly.Package Includes:1set brushless solar fountain pump
