This product is a solar powered direct drive water pump without an additional battery, and the height of the water spray depends entirely on the strength of the sunlight. When the sunlight is weak, the water pump will not work continuously and will automatically start repeatedly until the sunlight reaches a certain intensity, and it will automatically resume continuous operation. When the solar panel receives sufficient sunlight, the water pump will start within 3 seconds. This solar water pump adopts Hall elements with high sensitivity and low power consumption, and is driven by efficient and intelligent electronic circuit, and adopts the volute design in fluid mechanics for the impeller cavity to reduce the resistance of water flow, so that the comprehensive performance is better than that of the traditional structure. The efficiency of the solar water pump is increased by 20%. The water pump can be connected with nozzles of different shapes to spray different types of water. Water spray height: 30-60cm, when connecting different nozzles, the water spray height will be different. Rated voltage of water pump:DC 7V Rated power of water pump:1.0W Maximum lift:110cm Maximum flow rate:190L/H Maximum spray height:30-60cm (the spray height may vary depending on the connection of different nozzles) Solar panel voltage:7V Solar panel power:1.5W Different batches may result in different product appearances, printed text, and colors, which do not affect usage Colour:Black Material:plastic Size:Solar panel size:160mm in diameter Package Contents: 1 * Solar panel(with Water Pump) 6 * Nozzle Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
