Operating Voltage: DC 48VRated Power: 400 Watts (approx. 0.5 Horsepower)Maximum Head (Lift Height): 60 MetersMaximum Flow Rate: 3 cubic meters per hour (3 m3/h or 50 Liters per minute)Outlet Size: 25 mm (1 inch)Impeller Type: Plastic / Centrifugal structureSolar Panel Matching: This 48V system works best when directly paired with solar panels providing a stable DC supply. Typically, two 250W–350W panels wired in series or configurations matching a 60V–90V open-circuit range are ideal.Polarity: Pay close attention to the positive (+) and negative (-) terminals printed on the label. Reversing polarity can damage the DC motor components.Dry Run Warning: The safety label highlights "FORBID WORKING EMPTY." Running the pump dry outside of water will quickly cause overheating and permanently damage the internal plastic impellers and seals.
