Threephase 440V Variable Frequency Drive and Solar and Wind Power Inverter (Model Threephase 440V01) Key benefits Optimizes motor control and renewable power conversion for threephase 440V systems. Provides precise motor speed control and soft start capability to reduce mechanical stress and improve process stability. Integrates with solar and wind power systems to improve conversion and allow controlled output to threephase motors and equipment. Supports multiple power ratings to match different motor sizes and applications. What this unit does Functions as a VFD variable frequency drive and frequency inverter for threephase motors. Acts as a motor speed controller for consistent rpm control, torque management, and start/stop sequencing. Works as a power inverter component in solar and wind installations to help convert variable renewable input into stable threephase output. Key specifications and compatibility Voltage: threephase 440V input and threephase 440V output. Available power variants: 0.75 kW, 4 kW, 11 kW options and a 4 kW 5HP 440V variant listed as 440V 5HP 4kw. Model identification: Threephase 440V01. Universal threephase compatibility for standard industrial motors and equipment rated for 440V threephase. Performance and functionality Adjustable frequency and speed range to match motor and process requirements. Soft start and controlled acceleration to limit inrush current and mechanical wear. Stable output suitable for continuous motor operation in industrial and renewable energy environments. Design and materials Built for installation in standard control panels or motor control enclosures. Electrical components and heat dissipation designed for sustained threephase 440V operation. Specific enclosure size and materials depend on selected power variant. Common applications Solar and wind power systems: condition variable renewable input and provide controlled threephase output for pumps, compressors, or local motors. Industrial motor control: regulate speed of conveyors, fans, and machine tools that require 440V threephase drives. Water and wastewater pumping: smooth start and speed control for pumps driven by threephase 440V motors. What to consider when selecting Match the drive power variant to the motor rated kW or HP (examples: 0.75 kW for small motors, 4 kW or 11 kW for larger loads; the 4 kW variant corresponds to a 5HP 440V option). Verify threephase 440V supply compatibility for both input and downstream equipment. Ensure enclosure space and cooling are adequate for the selected power rating. This VFD and inverter solution is intended for threephase 440V motor control and renewable power integration where precise speed regulation and stable threephase output are required.
