Factory Power and VFD Retrofit Concept in Freetown

Freetown, Sierra Leone 路 Example configuration: EV series VFD for pump or fan control

Factory VFD retrofit concept for motor control in Freetown

Soft start Focus

Project Background

This concept page shows how a Freetown factory or workshop can use EV series variable frequency drives to improve motor control. It is relevant for pumps, fans, compressors, conveyors, and machinery that currently run at fixed speed or direct-on-line start.

The Problem

Factories that run motors directly from grid or generator power may face:

  • high starting current;
  • pressure or flow instability;
  • generator overload during motor startup;
  • mechanical stress on pumps and belts;
  • wasted energy when flow is controlled by valves or dampers.

VFD Solution

An EV series VFD can be selected based on the motor nameplate, load type, and control objective.

NeedVFD role
Reduce starting shockSoft start and controlled acceleration
Stabilize pressurePID control with sensor feedback where required
Match process demandSpeed control instead of fixed-speed operation
Improve generator compatibilityLower inrush current than direct start
Protect equipmentMotor protection and controlled shutdown

Information Needed

Before recommending a VFD, Sun Energy needs:

  1. Motor power in kW or HP.
  2. Input voltage and phase.
  3. Equipment type.
  4. Load behavior.
  5. Required control mode.
  6. Whether the site runs on grid, generator, or solar hybrid power.
