Polycrystalline Silicon Solar Fountain Water Pump Cycle Quick Overview: The product is based on updatig the brushless solar pump technology products, overcoming the shortcomings of hard start, low efficiency, poor stability of similar products and even easier to start than the same power brush pump. Features: Make use of solar energy, need no extra power, energy-saving and environmentally friendly. Polycrystalline Silicon. High Quality. Quick start. High efficiency. Stable performance. Easy usage and operation. Long service life. Specification: Solar panel power: 7V, 1.4W, 160MA Solar panel size: 11*11cm Brushless pump input: DC 4.5-10V Max flow quantity of pump: 170L/H Delivery head: 75cm Maximum delivery head: 70cm Cable lenght: about 320cm Life time: ≥ 20000hours Working time: 8:00am - 5: 00pm(on sunny day) Delay: ≤3s Color: Black Net weight: 162g Package size: 11.5*11.4*5.3cm Package weight: 195g Restart: if sunshine is off, can restart within 3 Seconds when sunshine is back. 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 continue to 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. The numbers on the back of the solar panel are product model, which will be various in different batches. Due to the cutting ways in different batches, solar panels are randomly sent in 2 patterns. ((doesn't affect the performance of product)) Please in kind prevail. Package Includes: 1 * Solar fountain 1 * Small parts for mounting 1 * User manual
