Description

MODEL: Tonanco 4HS8-400-18.5T

Tonanco 4HS8-400-18.5T is a solar power 4 inch submersible borehole pump with stainless steel impeller and high speed frequency of 6000rpm. The distinct advantage of this series is the AC/DC Hybrid functionality.

Descriptions & Constructions

• These pumps are widely recognized in the industry for their 6000 RPM high-speed permanent magnet motors, which allow them to be smaller, lighter, and more efficient than traditional 2850 RPM pumps.

Key Features

• High-Speed Operation (6000 RPM): The permanent magnet brushless motor runs at double the speed of standard pumps, delivering higher head and flow in a smaller form factor.

• AC/DC Hybrid Power:

  • DC Mode: Connects directly to solar panels (PV array) for off-grid operation.

  • AC Mode: Compatible with single-phase or three-phase AC (generator/grid) for backup during night or cloudy days.

• Advanced MPPT Controller: The external controller uses Maximum Power Point Tracking (MPPT) to adjust the pump speed based on sunlight intensity, achieving >98% solar utilization.

• Protection Functions:
  a) Dry-run protection (well water shortage).
  b) Over-current / Over-load.
  c) Over-voltage / Under-voltage protection.
  d) Phase loss protection.
