About VSRE48-009 - Crompton VFD - 3.7 kW / 5HP 3-Phase 380V Solar
The Crompton Greaves Emotron VSRE48-009 is a heavy-duty 3.7 kW (5 HP)
Solar Variable Frequency Drive (VFD) engineered to operate high-capacity, high-head water pumping networks. This model utilizes the slightly optimized
Frame Size 2 (VSR2) enclosure chassis variant, keeping it highly compact while significantly boosting its internal electronic current capacity to drive robust 5 HP three-phase motors. [

Electrical Sizing Specifications
- Power Capacity: 3.7 kW / 5 HP
- Rated Output Current: 9.5 Amps (Handles higher sustained mechanical loads for deep well irrigation)
- Maximum Input DC Current: 18 Amps
- Maximum Solar DC Input Voltage: 800V DC
- Optimal MPPT Voltage Window: 450V to 600V DC

Core Operational Features
- Hybrid Energy Source Optimization: Capable of prioritizing direct solar DC power during peak daylight hours while automatically leaning on a secondary 3-Phase 380V480V AC grid backup or generator loop during severe cloud cover or nighttime cycles. [1]
- 99% Solar Tracking Efficiency: Integrates an advanced, self-adaptive Maximum Power Point Tracking (MPPT) engine to extract peak water volume out of the solar panels even in low-radiance weather. [1, 2]
- Advanced Motor Profiling: Full firmware integration to easily pair with standard AC Induction Motors (IM) or high-torque, energy-efficient Permanent Magnet Synchronous Motors (PMSM). [1]
- Comprehensive Protective Suite: Built-in safeguards including pump dry-run mitigation, tank overflow control integration, output phase loss, over-current trip, and lightning protection. [1, 2]
