About VSRE48-004 - Crompton VFD - 1.5 kW / 2HP 3-Phase 380V Solar
The Crompton Greaves Emotron VSRE48-004 is a heavy-duty 1.5 kW (2 HP)
Solar Variable Frequency Drive (VFD) configured for a
3-phase 380V480V industrial grid backup or a high-voltage solar DC input. Because this 2 HP model shares the exact same high-voltage architecture as the 1 HP model, it remains on the
Frame Size 2 (VSR2) enclosure platform. [

Physical Dimensions & Weight
The physical dimensions match the standard Frame 2 chassis precisely: [
1]
- Height: 173 mm (6.81 inches)
- Width: 110 mm (4.33 inches)
- Depth / Length: 135 mm (5.31 inches)
- Total Weight: 1.5 kg (3.31 lbs) [1, 2, 3]
Mounting Dimensions (Center-to-Center Holes)
- Mounting Hole Height (H1): 163 mm (6.42 inches)
- Mounting Hole Width (W1): 100 mm (3.94 inches)
- Installation Screw Diameter (d): 4.5 mm (0.18 inches) [1]
Technical & Electrical Sizing
While the outer dimensions match the 1 HP version, the internal electronics are scaled up to support higher current demands: [
1]
- Power Rating: 1.5 kW / 2 HP
- Rated Output Current: 4.2 Amps (compared to 2.5A on the 1HP version)
- Maximum Solar DC Input Voltage: 800V DC
- Optimal MPPT Tracking Range: 450V to 600V DC
- Recommended Solar Array Power: 2.25 kWp (Kilowatt-peak) to ensure reliable pump start-up under varying cloud cover. [1, 2, 3, 4, 5]
Motor Performance Note
This drive is highly versatile and supports both standard 3-phase AC Induction Motors and high-efficiency
Permanent Magnet Synchronous Motors (PMSM). When driving a PMSM pump, the advanced software logic enables maximum torque output at exceptionally low starting currents. [
