Technical data: Solar collector energy: 7V, 160MA Solar collector size: 11 * 11cm Brushless pump input: DC 4.5-10V Pump flow rate: 150-200L / H Lifespan:> 20,000 hours Delay: <3s Color: Black Net weight: 190 g Package includes: 1 * solar fountain 1 * small parts for assembly Restart: if the sunshine is off, it can restart within 3 seconds when the sunshine is back. Brief overview: The product is based on updating brushless solar-powered pump technology products, which overcomes the disadvantage of hard start, low efficiency, low stability of similar products and it can still be lighter than starting the same energy brush pump. Features: Use solar energy, no need for additional power supply, energy-saving and environmentally friendly. Polycrystalline silicon. High quality. Quick start. High efficiency. Stable performance. Easy to use and operate. Long lifespan. Note: Products from direct operation Solar powered water pump, no external batteries required, a high level of water depends entirely on the sun, when the daylight is weak, the water pump does not work continuously, as soon as the daylight becomes stronger, it continues to work automatically. Solar panels and controllers do not immerse you in water, although it has a weak waterproof structure, but it is not suitable for long-term immersion in water. The appearance of the solar panel may show a slight difference, but it does not affect its use. Please advise in kind.
