Application

Tips: What occurs if the water pressure or flow rate is too low?
The small water turbine generator cannot maintain stable voltage if the flow is too low, which may lead to efficiency loss or operational failure. If the flow exceeds 20 L/min, the system may become overloaded. Maintaining the flow within this range ensures optimal performance.
