Description Specifications: Solar Panel Power: 7V, 160MA Solar Panel 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: 190g The package includes: 1 * solar fountain 1 * small parts for assembly Restart: when sunshine is off, can restart within 3 seconds when sunshine is back. Brief Overview: The product is based on upgrading solar brushless pump technology products, which overcomes the disadvantage of hard start, low efficiency, low stability of similar products, and it can start even easier than the same power brush pump. Features: Use solar energy, do not need additional power supply, energy-saving and environmentally friendly. Polycrystalline silicon. High quality. Quick Start. High efficiency. Consistent performance. Easy to use and operate. Long lifetime. Note: Products of direct operation Solar powered water pump, it does not need external batteries, a high level of water depends entirely on the sun, when daylight is weak, the water pump will not work steadily, once daylight becomes stronger, it would keep working automatically . Solar panels and controllers do not immerse in water, although it has weak waterproof structure, but it is not suitable for long-term water immersion. The appearance of the solar panel may show slight difference, but it does not affect the usage. Please in kind prevail.
