Wide working voltage: 18v-45v
Built-in MPPT controller to make full use of solar energy
Over-voltage protection/under-voltage protection: The pump automatically stops working when the voltage is too high or too low; Then every 10 minutes, when the voltage is restored to 18v-45v, the pump starts automatically and starts again
The water pump can connect directly to the solar panel in the sunlight without connecting the battery
Maximum Flow: 3 m³/h Maximum Head: 80 m (262.47 ft) Diameter of pump: 89 mm (3.5 inch)
