About VSRE48-006 - Crompton VFD - 2.2 kW / 3HP 3-Phase 380V Solar
The Crompton Greaves Emotron VSRE48-006 is a high-performance 2.2 kW (3 HP)
Solar Variable Frequency Drive (VFD) engineered for 3-phase 380V480V solar pumping applications. Because the internal power transistors and cooling mechanics step up to support higher current delivery, this specific 3 HP variant transitions into a slightly wider and deeper frame blueprint compared to the 1 HP and 2 HP high-voltage variants.

Electrical Sizing Specifications
- Power Capacity: 2.2 kW / 3 HP
- Rated Output Current: 5.5 Amps (Handles the extra current load needed for heavy-duty 3 HP motors)
- Maximum Solar DC Input Voltage: 800V DC
- Optimal MPPT Tracking Range: 450V to 600V DC
- Maximum Input DC Current: 10 Amps
- Recommended Solar Array Power: 3.3 kWp (Kilowatt-peak) to offset environmental panel degradation and high-heat field losses. [1, 2, 3, 4, 5]
Operational Specialization
- Advanced Motor Profiling: Built with specialized motor parameter tracking to run high-torque AC induction pumps or high-efficiency Permanent Magnet Synchronous Motors (PMSM). [1, 2]
- Up to 99% Tracking Accuracy: Dynamically computes the maximum solar energy extraction using an advanced Maximum Power Point Tracking (MPPT) software block.
- Sensor-Free Safeguards: Automatically commands the pump to enter sleep mode during deep cloud cover and awakens it once voltage thresholds stabilize.
