Specifications: Solar panel type: Polycrystalline silicon solar panel Solar panel: 7V / 1.12W Solar panel size: 110*110mm Pump power: 9V / 1.12W (for 1.5W solar panel) Max. Pump flow: 150L/H (for 1.12W solar panel) Max. Water height: 30-60cm Max. Pump lift: 150cm (for 1.12W solar panel) Pump size: 55*33*42mm Cable length: 3m Note: * The pump products direct-drive solar water pump, no external batteries, high degree of water depends entirely on the strength of the sun, when the sunlight is weak, the water pumps do not work continuously, once the sunlight is more strong continues to work. * Please put the pump into the water to work. or itis lifesspan will be shortened. * Do not submerge solar panels and controllers in water; otherwise it will be damaged and could not work.
