Veichi 2hp AC/DC Solar Surface Pump

Description

The Veichi 2hp solar surface pump is suitable for a variety of applications including agricultural irrigation, household water supply, and livestock watering. The Veichi 2hp solar surface pump works with both AC and DC power supply using multi-functions of AC and DC MPPT controllers.

FEATURES:

• Max flow: 48m
• Max head: 17m
• NSK bearing
• Efficient PMSM brushless motor (PMSM: Permanent Magnet Synchronous Motor)
•  Motor: IP68.
• Advanced fluid technology.
• Mechanical seal of silicon carbide/graphite composites ensures long service life and reliable operation.
• 180°C high-temperature resistant copper wire with Class F insulation.
• Cold-rolled silicon steel stator and rotor.
• 38SH NdFeB magnet with high-temperature resistance up to 150°C.
• Food-grade white mineral oil.
• Oil reservoir structure balances internal/external pressure, enabling pump submersion depth up to 120m.
• Premium angular contact bearings withstand high axial loads, are compatible with all hydraulic types, and offer extended service life.
• Real time working condition on LED screen: output power, output voltage, current, pump speed and error code.
• Auto frequency conversion: auto adjustment the speed/rpm according to solar power strength except for manual adjustment. Auto On/Off (with float switch ).
• Soft start:  impulse current-free to protect pump motor.
• No water hammer to protect the whole plumbing system.
• Multi-protections: protection against dry-run, over-voltage , over-current, high-temperature (reduce rpm when the inner temperature reaches 79°C), and output phase loss.

Solar Panel Connection

t’s recommended that the solar panel has a power rating 1.3 -1.5 times greater than the water pump’s power. Additionally, ensure the voltage of the solar array matches the voltage requirements of the water pump.
For example:
VEICHI DC Solar Water Pump
Power: 750W
Optimum input voltage: 90-120V
Maximum open circuit voltage: 160V
Recommended solar panel power ≥1.3*750w (power≥975w)
VMP(voltage at max) voltage >90v
VOC voltage <160v
Solar panels

• Power 330 watts
• VMP voltage 37.26v
• VOC voltage 45.64v

3 solar panels connected in series

• Power 330w*3=990w
• VMP voltage 37.26v*3=111.78v
• VOC voltage 45.64v*3=136.92v
