Product Introduction The product is based on updated the brushless solar pump technology products, Overcoming the shortcomings which the solar brushless pump hard start, low efficiency, poor stability and even easier to start than the same power brush pumpProduct specification Solar panel power consumption 9V 360mA Brushless pump power consumption 12V 210mA Maximum flow 300L/H Maximum head 150CM Product performance Start: The water pump will not working without sunlight, it will restart within three seconds once the sunlight re-appears. Useful life period > 20000Hours Working hours in sunny: 8: 00 AM~5: 00PM Note         Products for direct-drive solar-powered water 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, once sunlight is stronger it will automatically continuous work. Do not submerge solar panels and controllers into water even though it has weak waterproof structure, but not suitable for prolonged immersion in water
