About VSR23-9p5 - Crompton VFD - 2.2 kW / 3HP 1-Phase 220V Solar
The Crompton Greaves Emotron VSR23-9P5 is a 2.2 kW (3 HP)
Solar Variable Frequency Drive (VFD) configured for a
220V single-phase grid input or direct solar array DC voltage. Because it is built on the exact same
Frame Size 2 (VSS2) hardware housing platform as the previous 2.2 kW and 1.5 kW models, its physical sizing remains completely unchanged. [

Technical & Electrical Differences (VSR11 vs. VSR23)
While the outer physical dimensions match the 110V version (VSR11-9P5) precisely, the internal electrical configuration of this 220V model changes how you set up your solar array:
- Grid/Generator AC Input Voltage: 220V to 240V AC Single-Phase (as opposed to 110V on the VSR11).
- Maximum Solar DC Input Voltage: Up to 400V DC (Allows you to wire more solar panels together in a single serial string).
- Recommended MPPT Voltage Range: 250V to 350V DC (The sweet spot where the drive extracts peak daily water output).
- Recommended Solar Array Power: 3.3 kWp (Kilowatt-peak) to comfortably handle motor start-up surges.
- Max Output Current: 9.5 Amps to drive standard 3-phase 220V AC water pump motors. [1, 2, 5]
