Pump voltage: 7V DC. Maximum drop height: 110cm Maximum spray height: 85cm Pump power: 1.5W Maximum flow rate: 190L/h Solar panel voltage: 7V Pump power: 1.5W Maximum flow rate: 190L/h Solar panel voltage: 7V Solar module: 1.5W Solar module size: Ø 160mm (monocrystalline silicon) The solar water pump uses high sensitivity Hall elements and low power, combined with creates efficient intelligent electronic circuits, and adopts the principles of fluid mechanics to design a screw design in the cavity casing. The impeller is designed to reduce the resistance of water flow, making the overall performance better than traditional structures. Efficiency of water pump solar water has increased by 20%. It also solves current problems related to starting difficulties, low efficiency and low power. Instability Pumps Brushless Solar Water Pump. This product is a brushless solar water pump. solar water direct drive, which does not require additional batteries. The water spray height is 60 to 100
