Pump voltage: 7 V DC. Maximum drop height: 110 cm Maximum spray height: 85 cm Pump power: 1.5 W 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 highly sensitive and low-power Hall elements, combined with efficient intelligent electronic circuits, and adopts fluid mechanics principles to design a screw design inside the hollow casing. The impeller is designed to reduce water flow resistance, improving overall performance compared to conventional structures. The efficiency of the solar water pump is increased by 20%. It also solves the current problems of difficult starting, low efficiency and low power. Brushless Solar Water Pump Instability Pumps. This product is a brushless solar water pump. Direct solar water drive, no additional batteries required. The height of the water jet is between 60 and 100 degrees, 80 cm
